Dell OptiPlex GX280 mini-tower power supply problem

Q: Dell OptiPlex GX280 mini-tower power supply problem

I have a Dell OptiPlex GX280 mini-tower (smallest one thereis), and the original 160W power supply died a few months ago without warning. I ordered a new power supply, but accidentally ordered the wrong size (210W for one of the larger towers). I used it in the meantime until I could get the proper size (although the 210W supply wouldnít fit in the mini case Ė I left it out of the case and ran the wires through the power plug hole). The computer booted up just fine with this 210W power supply. I finally got around to ordering the 160W smaller correct size, but that power supply would not boot up the computer (just got an amber flashing light). Thinking it was just faulty, I sent it back and requested a replacement. The replacement did not work either. I ordered a third replacement, and the third did not work either! So now I am back to using the 210W power supply (No. HP-U2106F3) which does not fit in the computer housing. I know these Dell OptiPlex machines are notorious for having power supply and capacitor issues. But the question is, why will the computer power on using the 210W power supply? I contacted Dell and they were of no help whatsoever. The guy told me that 160W wasnít enough to power my machine and to order a 210W power supply correctly sized for my chassis. Gee, thanks! First of all, they donít make 210W that fit in the mini towers, and second of all, why did it used to work just fine??? Oh, and no I have not upgraded anything (i.e., video card, etc.) which could have caused the need for extra juice. Thanks in advance for any assistance!

Hi TechSpot Forums!

I own a Dell Optiplex GX280 Mini-Tower PC, and am seriously considering buying a graphics card for it.

My question to you is, which would best be compatible with my specs?

System Specs:

Dell Inc. OptiPlex GX280
Windows XP Professional Service Pack 3
3.00 gigahertz Intel Pentium 4
2552 Megabytes Usable Installed Memory
500.10 GB HDD

Current Video Card:

Name: Intel(R) 82915G/GV/910GL Express Chipset Family
Manufacturer: Intel Corporation
DAC Type: Internal
Approx. Total Memory: 128.00 MB
Current Display Mode: 1400 x 1050 (32 bit) (60GHz)

Does installing a graphics card mean you can achieve higher resolutions on your LCD monitor? That is partly the reason I will be purchasing one.

Thanks for any info or suggestions,

I need a better power supply so I can add a better video card. The power supply that comes with my SDT is really small and long and only 210W. They don't make official power supplies with more watts.

I've heard that the 1u server power supplies are the same size and should work with my SDT if it is ATX12V compliant. My question is will the power supply from a Dell PowerEdge 850 work in my Optiplex SDT? The part number for the PowerEdge's power supply is T3504.

Is there anything I need to take into account (connectors etc.)?

I'm new at this and would greatly appreciate any help.

A:Dell Optiplex 745 Mini Tower Upgrade

Hi Asfand_Munib,
Before installing a new processor, please update the BIOS to latest version from Here.
Note : Please save and close all running programs and documents and disconnect all external peripherals (printer, flash drives, external hard drives, etc) and connect the computer to a surge protector before updating the bios.
If all the lights are green and you are not receiving any beep codes from the system then it means that the processor has been installed correctly. Please check if the keyboard lights (Capslock, Numlock, etc) respond when you press the corresponding keys. Please verify the connections on rear of the system and check if they are connected firmly. Also, check if you are able to hear any windows jingle sounds after some time when you power on the system. Please share the exact model of Optiplex 745 you are using as it comes in 4 form factors viz Ultra Small Form Factor (USFF), Desktop (DT), Small Form Factor (SFF), and Mini-Tower (MT). A picture is attached below.

Please reply with the information. Will take it further from there.

I cannot get an OptiPlex 755 Mini Tower to power on. It had been running fairly continuously in an office environment on a APC battery backup/surge protector until it failed Monday morning. Then there was some orange light that was flashing or continuous. When the computer was turned off, it would not come on again. Sorry for the vagueness, but this is second-hand information. I found a fair amount of dust inside, but I've seen far worse on computers
When I push the power button I get no change: no light in the power button, no diagnostic lights, no sounds, no fan movement. When I connect it to power the "AUX LED" light on the motherboard comes on a solid yellow/amber so the PSU is putting out something.
Is this likely to be a PSU problem? Is there some way to pin it down other than buying a replacement PSU?
Thanks for any help,
Joe M

Hi everyone:

I was curious if anyone else experienced this issue? I have a Dell OptiPlex 7010 desktop/mini tower that I bought off the official Dell site. I configured that mini tower to have an SSD drive as the main drive, which I like very much, except one very annoying issue. Sometimes out of the blue Windows 7 will hang up, I can't click anything and the mouse starts spinning in a circle. This continues on for about half a minute and then it always comes back to life. Suddenly I start getting all my previous clicks moving windows, opening things, etc, all at once. This happened at least a dozen of times by now and I started to notice that when this happens the HDD/SSD LED on the case glows solid, which made me suspect that there's something going on with the drive itself.

Does anyone know what's going on and how to fix this?

PS. I tried contacting Dell support about this issue but they are pretty useless. I spent several hours in a chat with a guy once that eventually simply hung up on me. Then I emailed someone at Dell, for which the guy replied with instructions to run their hard drive diagnostic tool, which I did, that did not show any errors. (Note that I don't have a hard drive, it's a solid state drive.) I replied to the guy only to never hear from him again.... So I think I'm pretty much done with the Dell support

My refurbished dell optiplex GX280 worked fine until a month or so ago when I moved it to another room in my home. When I powered up, the power light was blinking amber. I tried all of the options that did not require buying new parts du to financial reasons, so it's sat since then.

I just decided to look at it again and powered it on. Everything seemed to start OK but no dispay. The diagnostic lights indicated faulty memory. I then located and removed the faulty DIMMM, and it started right up.

About ten minutes later the computer shut off by itself back to the blinking amber power light. :evil:

Any info would be appreciated Thank you. :grinthumb

There is a design problem with the OptiPlex 7040 Mini Tower case that leads to excessive noise. The plastic grid panel on the front of the case rattles loudly, especially when the system is operating under a heavy computational workload. I'm not certain if the vibration originates from a fan or from the hard drive, but it's clearly causing resonance in that plastic front grid panel. I'm certain that the front panel is what's making the noise. The noise goes away completely if I press my finger against the front panel (and resumes immediately when I remove my finger). My current workaround to the problem is to prop up the front of the case with a piece of bubble wrap. Dell's engineers should consider altering this case design to address the vibration problems.

I've had an intermittent problem with a Dell Optiplex GX280 P4 3.2GHZ.

Was able to install both WinXP and Ubuntu 8.10, however after updates Ubuntu crashed and would not reload. WinXP intermittently got the blue screen of death.
Ubuntu would not reinstall.
Ran Memtest, and the RAM appears to be ok.
Replaced the Hard Drive, same problems, Ubuntu still refused to install.
The computer shop said it was probably the mobo or the processor (duh)
I won an Acer Veriton 2800 in a scholarship and surprise, surprise, it has a compatible P4 3.2GHZ processor, so I might switch the processors and see what happens, if it's still buggered, I'll assume the mobo is at fault. -I don't get the Acer till next week.
If that is the case, I'll probably buy a new motherboard and rebuild the comp into an ATX case I have lying around.
Will update the processor at a later stage

Any ideas on diagnosis? Anything I might have missed, or not thought to check? Cheers

A:Diagnosing a problem; mobo or processor on a Dell Optiplex GX280


If Windows XP is throwing off a BSoD then what error is it reporting? I haven't done this in awhile but I recall you need to go into the setting and make it so that upon BSoD the PC doesn't restart until you say to so you can see the error. Also, check the dump files. You'll need to Google the rest of that.

Good Luck,

Do you mean "heat sink" rather than "power supply"?
You didn't say which form factor 740 you have, mini-tower, desktop or small form, but go here and look at the motherboard diagram for whichever model you have to find the location of the fan connector on the board.
Make sure the PC is powered off, unplugged and you press/hold the power button for ~15 sec before you do anything inside the case.

There is no point to X64 cpu in this model.  The GX620 is the same and has a 3.5 gig ram limit based on a chipset limitation not on 64 bit OS or not. You have a Hyper thread single core P4.
Zero advantage to EMT64 cpu on this model.
Intel didn't implement 64 bit until the 600 series on socket 775
The GX280 is too old.  The GX620 can go all the way to windows 10 but it too cannot take advantage of more than 3.50 gigs of ram regardless of the physical amount installed.

It can if you remove the floppy drive and mount the hard drive in that spot. You'll need to use an IDE cable with two connectors and use it for the CD/DVD and the new hard drive. I don't recall if there was a SATA connection on the motherboard, if so that would be the way to go.

A:Optiplex 760 Mini Tower Quadcore
Q9650 is max.  Bios update should be done BEFORE trying to change cpu.

 750 TI only fits in the TOWER and Only After Cutting the Bracket off and ONLY with Short cards with 1 fan aka 8.4 inches max.

There are no single slot cards.   If one was put in they hacked the bracket in half or removed bracket altogether.  If you remove the bracket on EVGA models you can use tin snips to CUT OFF half the bracket.  The cooling vents are blocked so you might also have to drill holes in the case to let air out.  Long Cards with 2 fans DO NOT FIT and WILL NOT EVER FIT into the Tower or any other size.

Only Short cards with Short fans Fit.

Well first off I upgraded the RAM on this machine. I have upgraded the RAM on other machines lots of times. I grounded myself before I did any work on this computer. I took out the old RAM and put in two sticks of 2 gigs of RAM.

After I hooked it up again I got the "jet engine" noise. I saw the amber light on the power button and then it got LOUD real fast. I waited to see if it will go away but it didn't. I had to pull the power plug to turn it off.

I then opened it up again and made sure their wasn't any loose connections. There was not. I hooked it up again and hoping it will give me something beeps or anything but nothing. No power, no fan noise, no hard drive noise and no beeps. I checked all the cables outside and made sure nothing was loose but everything is okay. Not sure what to do now.

I hope the mobo is not fried. Would it be the power supply? The only other thing I can think of is maybe I need to put in a new cpu, a new heatsink and of course thermal paste. By the way this was a hand me down computer from my mother-in-law company. So I would say it is about 4 years old.

I was reading about the Dell Optiplex GX280 and learned that they have bad quality capacitors on the motherboard. Maybe it has blown capacitors on the motherboard.

Has anyone run into this same situation and how did you solve it? Probably spend the money on a hand built computer. I think.

I hope you guys can help me out here.

I found one on eBay and received it yesterday.

But the socket on the motherboard has more pin holes than the processor has pins. On the motherboard the socket is marked (Foxconn C-3598). If I plug in the CPU into the socket, there is extra holes along the side and the bottom.

Does (or will) this processor fit and work in this socket?

Hey guys!
Is it possible to install Windows 7 on this machine?
My dad found a Optiplex GX280 lying around somewhere.
He brought it back home and I was pretty impressed by it's specs.
Windows XP Professional Service Pack 3 (Build 2600)

Memory (RAM) 503 MB

Intel(R) Pentium(R) 4 CPU 2.80GHz

2773.4 MHz

Am not so sure about a graphics card,
I opened it up and it seemed like something was missing.
It doesn't really matter now.

I will use this computer as a secondary in my home,
Am going to set it for my dad,
So he won't use mines anymore.

Am having second thoughts about installing Windows 7 on this machine because of it's low RAM and it's older chipset.

If I do install Win7 on this machine,
Am going to remove all the eye candy from it so it won't rely as much on it's graphics.

I also posted this almost exact post here:
Dell Optiplex GX 280
(Since the author of that post also talked about the same machine)

The reason I want to install Windows 7 on this computer is because of HomeGroup.
I have a lot of files on my main computer that I might need in the future.
So in a long shot, I just want to sync up both computer in my network.

Should I go for it?

16 GB available hard disk space (32-bit) or 20 GB (64-bit).
DirectX 9 graphics device with WDDM 1.0 or higher driver.

Windows 7 System Requirements

Like you said, the RAM would be the an issue.
I would bump it up to at least 1GB..

Drivers for Windows 7 might also be an issue, Check with Dell Support Page for the model an see if they have any drivers for Windows 7.

You need a graphics card/device that supports at least DirectX9 in additon WDDM (Started when Vista came out)

Research before installing!!

If you have the Windows XP disk than I would maybe try it out (I say maybe because if it was me I would just accept XP but that does not mean it can't be done.)

If anything goes wrong or you can't find drivers that Windows 7 will accept than you can always re-install XP. (If you have the disk)

Although HomeGroup is a cool feature you can share a folder or even a drive in XP, or buy a network storage unit. That way any computers in your network can have access to files and folders

In the end all the specs are there if you bump the RAM to 1GB, just don't expect it to be fast.

Hope this Helps, and Happy Holidays!

I got a Dell Optiplex GX280 tower, P4 3.2Ghz DDR2. When I start it up there is a long beep followed by 5 short beeps. I know the beeps mean something, but I don't exaclty know. I've tried changing the RAM, to no avail. Could it be video, because there is no signal to the screen?

I recently bought a gently used Dell Optiplex GX280. It came with Ubuntu which was removed when I installed Windows 7 Professional x86. The install had its rough moments but I was finally able to complete it successfully. The problem is that I can't seem to get the sound to work; my computer keeps saying "No audio output device is installed". I am using a pair of speakers plugged into the audio jack in the back of the computer.

I tried going to the Dell website but they just said that my computer is not compatible with Windows 7. I tried the XP driver once straight from the download and a second time running it in XP compatibility mode, but neither worked.

Then I looked on Google and checked some forums. A few people had successfully used the Windows Vista driver in Vista compatibility mode, but that didn't work for me either.

Every time I try installing a driver I get the error message "Installation failed! The audio driver files do not support your computer hardware." I'm not sure what to do next, besides eschew the computer and buy a harmonica to make my own music (not polite when you're tone deaf like me ). Please help!

One extra piece of information: I haven't connected the Dell to the internet yet. All these downloads have been done on my Acer laptop running Vista, then the zipped folders are transferred via flash drive to the Windows 7 Dell. I don't think this should be a problem, though, since I have done all this successfully befo... Read more

A:Audio Driver for Dell Optiplex GX280

Hi Nekton,

If there are no drivers for win7, you may be out of luck. However, before we give up on you lets try a few things.

1. Providing that the vista drivers you downloaded were for exactly the same hardware device, it may be possible to force the install using the legacy hardware function.
Open up device manager, right click and select install legacy hardware, the choose your vista drivers.
This is originally designed for installing hardware that is not plug and play; but may work for you.

2. If still no good, it might be possible to alter the ini file and name of the vista drivers so that win7 does not recognise them as blocked drivers. Here's the steps from a previous post Leadtek Winfast TV2000XP RM Drivers ? with my TV card.

3. Lastly (and more ugly) is an external usb sound card. I bought one with headphones attached from Sony for around A$40 (actually mine was usb headphones; but I found I could unplug the headphones and attach any speakers to it.

I bought this PC used on ebay last week and it only boots for between 3 and 8 seconds and gives an error msg that says:

"Alert! Previous attempts at booting this system have failed at checkpoint [Ithr]. For help in resolving this problem, please note this checkpoint and contact Dell Technical Support."

Sometimes when you start it the CPU fan sounds like its going way too fast, Ive read this is because the PC hasn't booted enough to control the fan speed yet.

Ive also read that this model of PC has been plagued with problems regarding expanding or leaking capacitors and when I looked at the mobo with a flashlight, sure enough there is 1 capacitor behind the cpu that looks exactly like what a leaking capacitor looks like in the photos Ive seen on the net. But, the photos I have seen of PCs that have failed due to this problem always seem to have about 6 or more failed capacitors that are bloated and leaking.

And I just find it hard to believe that an ebay top seller pc store with 100% positive feedback would ship me a pc without turning it on first so I have a slim hope that it may be something else. Ive tried running it with no drives attached and also with 1 ram stick instead of the 2 it came with (tried them both one at a time) still same thing. And I removed the little battery for 10 minutes to reset the bios, no change.

I have my ACT and MCSE certifications. I've been workings on pc's for over 17 years. But now I've ran into 2 problems that I haven't figured out how to fix yet and this is with Dell computers that have USB ports only and no ps/2 ports.
First, When I install Windows XP Sp2 on a Dell computer while using a usb mouse and keyboard. After the install is complete and configured and I have removed all the question marks in the device manager by installing the appropriate drivers. Everything works fine. But if I turn off the pc and unplug it to move the pc to a new location. I turn it back on and Windows try to find the usb keyboard and mouse but it doesn't completes because I have to click yes for it to search for the HID compliance device driver. But I can't click anything because the mouse and keyboard is not working until the plug/play install completes. I've updated the chipset from the dell support site and that doesn't work. I updated the chipset from intel which are the newest drivers and that still doesn't work. I go into the BIOS and the USB setting is enabled or if there is a legacy option for USB I enable that one too. Help!
Second, on a Optiplex GX280 after installing Windows XP Sp2 on the pc. I go into the device manager to configure all the devices with the appropriate drivers that has question marks except for the vga. The pc works and is running fine. Now as soon as I install the video driver software that installs a chipset as well the pc works fine untill I reboo... Read more

For both computers it sounds like a driver is causing problems. Have you tried just using the drivers that came with the computers on the Drivers & Utilities Disk?

Thank you for writing to us ! 
To understand the cause of this issue I would ask you to try these steps and advise the result ,
*Disconnect the system from wall socket ,then press and hold the power button for about 15 - 20 secs .Then connect the system to wall socket and try to turn on the system .Here we are trying to release static charge from the system .
*Then disconnect all the peripheral components from the system and try to turn on the system .
*If the above step fails then remove all the memory modules from the system and try to turn on the system with only 1 memory module at a time .
If there are any more queries do reply to this post with system service tag sent via private message .

Hello, my Optiplex 7040 just arrived this week.  I bought a Kingston 120mb SATA ssd in a 2280 stick, so I'm trying to see if I can use this for my main boot drive (Windows 10) and then move the 500gb 3.5 Sata drive over to a storage drive.When I install the 120gb 2280 stick into the M.2 slot, and load the bios...   *It shows up under General / System Information / PCI information / Slot5_M.2 & also under Device Information / SATA-4   *When I look under System Configuration / Drives, it also shows up under SATA-4 here as well.  However, it's showing up as a 0gb Drive under 'type'!
So when I boot from a USB drive to try and reinstall Windows on this M.2 stick, it's not showing up at all.
When I connect the M2 SATA drive and load Windows on the existing 3.5 SATA drive that came with the 7040, the M2 2280 stick shows up in 'device manager' under the hard drives.  The serial # there corresponds to a Toshiba-form hdd; unfortunately, I can't do anything with it in Windows 10.
SATA operation is set to AHCI, and I am booting into legacy with the USB.Any thoughts?  I'm wondering if maybe I have a dead memory stick.  There's no real way I can test it on another computer to see what happens.

For Windows 10 you should have a UEFI Boot with SecureBoot Enabled. The USB should be made using the GPT partition scheme for UEFI BIOS. I hope you mean 120 GB and not 120 MB....

I've read all over here, and over the internet for problems like mine. Except, there aren't any. The ones I do see see are problems involving a flashing amber light. Hah, funny. I USED to have that problem, then the light stopped going altogether.

I plug it into the wall, and nothing happens. No light. I opened it up. The little light in the motherboard was off. I looked everywhere, but the problems usually don't go this far! It's refurbished, but my PC's mother board dates all the way back to '03. I checked all the cappacitators: Flat and clean of any brown gunk. My fan has always been loud as hell, so I think that either the motherboard died on me, or the fan broke and took out the PC along with it! I know my power strip works. I have my modem plugged into it, and there's been no changes about what's been plugged into that for a year. It was working last night, then I try to turn it on, and the amber light flashes.

I noticed that the ports had one of the safety things pulled out so that the metal teeth were showing, but it'd been like that for a while. I was told to make sure none of them were touching, with some were, so I used pliers and separated them nicely. Recently I plugged something into it (twice, out of habit) and it warned me on my monitor that it shorted out. The second time was the last time I had it on. Is that the problem, or what?

A:Optiplex GX280 power fail, and not the normal kind

The power supply has died, but you may have issues with that '03 motherboard too. That "Port" is a USB port and if the pins were touching at all, they may have eventually shorted out the power supply. If the motherboard is that old, the power supply may be as old, right?

From Yesterday morning, I'm facing a problem with my Dell Optiplex GX280. I have googled all possible solution for the problem, but nothing helped me.

Actually my problem is when I turn on my PC first time it got boots normally once logged in the problem starts, The desktop gets freeze. I unable do anything like (CTRL+ATL+DEL to open Task Manager) only way is to make a hard shutdown. But when i try to start the machine immedeatily for the second time the power light stays orange and the CPU fan present over the heat sink runs very fast with loud noise. And nothing comes in the screen.

This is happening today also. So what could be the problem. MB shouldnt be a problem because sometimes its booting and up for 2-3 mins. So is this the problem with heat sink or CPU fan?

Please help me. Thanks in advance

hi, I am going to upgrade my graphic card to ATI 5770 so I need a new power supply which has power about 550--600 watt. But the most frustrating problem is that I failed to find a proper power supply with the correct dimension.
I have an HP pavilion e9300 which uses a very wired power supply tower-150mm(W) 86(H) 140(D). But so far all the PSUs I found is the standard size --150mm(W) 86(H) 150(D) which cannot fit in my setup.

So could any PC God give me some suggestion, please??
Is any PSU with the size of my tower or can I just simply install a bigger PSU which can still successfully power up the comptuer?

Thx in adance.

I have a Dell Optiplex Gx280 and it won't start, an amber light is flashing in the power button. I have read the manual and it states the following:

If the power light is blinking amber ?

The computer is receiving electrical power, but an internal power problem might exist.

Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
Ensure that the processor power cable is securely connected to the system board.

I did both things but it still does'nt power up.

I opened the comptuer and the stand by power light is on, (the one in the system board). I don't know if this is ok.

What else can i do?

I just got an Optiplex gx280. The reason that I got it was because after turning it on, the fan would start to speed up to the point of it sounding like a mini jet engine. I took a look at it and the hard drive is fine, so is the RAM, & the capacitors. I think that the problem is that there is no thermal putty between the fan & the processor. Also the computer won't boot. When I turn it on this is what it does:
It starts running
The fan starts speeding up (Still no boot screen, or anything else)
The fan tops speed
A couple seconds later the computer shuts off and an amber light starts flashing (Not the one on the Mother Board)
Does anybody know how to fix this?

Dear Users

Many persons have problem with GX280 system when you witch turn on ,the orange light display and no display and fan is loud or no boot system.
some peoples thought this is ram problem or mother board problem .
So here is simple solution i have same problem and i read an article and solved the problem.
This idea will you help all of you.
When the situation as describe up , just do it simple because its problem reason of processor heat up problem.

1- Just open case and see Processor fan
2- open fan clip and split fan from mother board the heat sink attached with fan.
3- now you will see the processor

now you need to take step i will show later time with pics
inside of processor have a clip that hold the processor so open the clip .
a plate is up of processor ,it's steel plate .
you can also on processor plate have chemical layer
when you open plate up of processor ( Note : remove this plate from mother board and close processor inside clip )
and directly keep fan with heath sink on top of processor and clip to close it.
Because reason of this plate processor got heat up and don't properly touch with heat sink.
just turn on your computer it will never make problem and even never fan make noise loud.

Hi, Currently I'm using a dual core 6850 and I'm thinking about buying a quad core. I have a PSU of 500 W as spare.

Can i replace the CPU to a Quad Core without changing the cooling system?

A:replace dual core CPU by quad core what about heatsink? in Mini Tower 755 Optiplex

These are the specs of the spare PSU. Aren't they better than the original Dell PSU?
That power supply is ATX and not EPS12V
Better is not the issue.  Dell power supplys are 80 percent efficient not 70 percent ATX.  The -5v rail is an issue as well as this may cause a motherboard fire or damage your system.  Its a dead giveaway that this is a power supply from 1990 to 2000.
What current is on which rails is not trivial. There is a single 12V RAIL on that unit and its max is 17A
EPS 12V units have multiple rails of 12V @ 18 amps each.  MAX Power on the 12V rails is 264w not 204w
That unit has a lot more on the 5V and 3.3V rails at the expense of the 12V rails and CPU 4 pin connector. So no that spare unit is not likely to work well if at all.

Recommended update or replacement is EVGA 750B1

It is a PCI Express 2.0 x16 card and my Optiplex has a slot for that kind of cards, even if it is a PCI Express 1.0 x16 it should be downgradable.

Hi out there to Vistax64. I am a recent XP to Vista user. I have a Vostro 200 mini tower (specs below) that has been running XP pro for the last few years - couldn't stand the GUI anymore lol - so I installed Vista HP and am very happy with the new interface and features. After tweaking some, the desktop appears from cold start in 30 seconds or so and almost everthing runs as snappy as it did before with XP. But the task manager is showing an average use in physical memory of 1.17 gigs, CPU usage is higher, and some, not all, internet pages scroll slowly e.g. Yahoo news pages, Hearts of Space etc. where as they were fine before. Everthing else on the internet, including this site, works well - though a few installs like Starry Night Enthusiast and a John Deere farm game are slower.

My question is this: Would installing a seperate video card give me better all-around performance or would another gig of ram do the trick? And what brand/type of video card do you folks recommend?

Intel Core2 Duo E4500 @ 2.3ghz
2 Gig of Kingston RAM

A:Video Card For Dell Vostro 200 Mini Tower

Windows will allot 50% of your ram by default, for when you need them programs. Remember, rams fastr than hard drive, and why have all that ram and not use it.

For your power supply, a nvidia 430/440 or an ati/amd 6450, maybe get away with a 6550... Seasonics are quality.

The slowdown is probably because Vista is a bit more of a beast than xp, and graphics can be a bit more hefty.

We purchased two M800 Full size tower machines.  We need to add additional drives, but the PSU only allows for one additional SATA Connector.  The PSU is using a 10+4 pin connectors and I cannot find a PSU or adapter to adapt a 24 pin PSU.  What options do I have?  Is there such an adapter?

i have a Dell Vostro Mini Tower with the following specs:Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
4GB RAMIntel(R) HD GraphicsI have ran a System Requirements check and it says I have 2048MB of Video RAM.  i would like to upgrade this to 4GB if possible.  would anyone be able to recommend a card that is compatible with my computer?I understand the wattage of my power supply matters also, would anyone know what this is?Thanks in advance

A:Upgrading Video Card on Dell Vostro 270 Mini Tower

The 2GB you are referring to is how much system ram is being given to the onboard Intel GPU video to use. You cannot increase that to 4GB. But you can add a discrete PCIe x16 video card. The Vostro 470 has a 300w power supply. So that will limit you as to which video card you can use. The two video cards that we shipped on this model were =
YG17P Nvidia GeForce 640GT 1GB67V2J Nvidia GeForce 620GT 1GB
Or you could remove our power supply and install a higher wattage power supply and then get a better video card.

I have a Dell Vostro 230 Mini Tower, and it currently has the Intel Pentium E6500 processor. I would like to upgrade to something better, because my current processor does not meet the minimum requirements of some games I would like to play. I was wondering which processors I could upgrade to? I know that the new processor has to fit the socket on the motherboard, but I don't know how to find out what socket my current motherboard has, or even what motherboard it is.
I would also like to know, if I don't upgrade the processor, but instead get a new motherboard, can I get any motherboard, and plug it in, and will it come with a new processor, or will it have to fit my current processor? Does upgrading the motherboard make much difference to the CPU speeds if I don't actually upgrade the processor?
I am running Windows & SP3, DirectX 11, with 4GB RAM, and i also have an ATI Radeon 5670 HD Graphics Card, and a 300W power supply. 
Would I need to get a new power supply if I upgraded the motherboard or processor?

A:M70e Tower-memory, graphics & power supply upgrade

If you don't wish to buy memory from Lenovo, both Kingston and Crucial have 'System Specific' memory for your system that are guarranteed to work. Memory timings must be match what the BIOS expects for the system to recognize it, and generic memory often doesn't work.   
Use your Hardware Maintenance Manual for instructions on how to upgrade the memory. After making any memory change, run 2 passes of MemTest86 to ensure all is well.    A few older system types (eg. some models of M58), required a BIOS update to support 4 GB modules.   I'm not familiar with the M70, but it's probably similar to the other models.   If you take the cover off and measure the existing supply, then you'll know if it is a ATX or TFX standard. )
The Mini-Tower uses a standar ATX power supply, and the SFF a standard TFX pwer supply. A power connector adapter (ATX to Lenovo) is required for M92 and forward. For the SFF, the maximum aftermarket TFX is 400w, with 350w being more common -- not a huge increase over stock. For the Mini-tower, I have had an 650w aftermarket Corsair in mine (I recommend one that is semi-modular and shorter, as space is limited inside the case.

I was wondering what replacement options there are for this unit. I've asceratined from checking posts that not being able to boot up and a flashing orange power light indicate the possibility of death and this, accompanied by a fortnight of power surge warnings on the isb hub convince me time's up It's a second machine but I'd really like to maintain access to the programs I've loaded. The posts indicate the the quality of components in this machine is pretty ordinary so a non-Dell solution would be good.

Like so many others on the web, I recently got the flashing amber lights of death on my pc. It would take longer and longer to power up until now, it won't power up at all. I did plenty of googling and found that these computers have a reputation for having bad capacitors. I opened my power supply up and sure enough, 2 or 3 of my capacitors are bulging and/or leaking.

I won't dare try to replace the capacitors but I am willing to give a new power supply installation a try. I don't want to walk into Best Buy or a repair shop blindly and I've seen some articles of power supplies that need to be modified in order to fit. I don't want that but I don't think I want to get a replacement from dell either.

Is there a website I can go to check compatibility? The power supply installed now is a Dell cx305N-00. I can post all the specs if necessary.

Also, am I biting off more than I can chew with replacing it myself or should I just suck it up and let a repair shop handle the power supply and installation?

FWIW, I haven't upgraded or installed anything new on the computer and other than some NickJr games, we're not into gaming so I know I don't need a power supply with heavy duty wattage.

I have been searching for some time for a mini atx power supply

At the mounting face it is 5"X3.5"
One screw hole is offset along the small side rather than the long side like atx.
I have a microatx in it right now,but would like to get one that mounts properly
and close up that gap.
Need something that is 400 wat+ and doesn't cost an arm and a leg.
Anyone seen these anywhere?
The case is out of production,doesn't have a model number and isn't
listed at the moneual site any more.
I don't have the old supply any more.

A couple of years ago, I installed W7 on my optiplex took some searching and asking questions, but I finally found the right drivers, updates, etc.for everything to work properly, but I succeeded. The primary issue for me was being able to watch movies in formats like mp4, matroska...I use Zoom Player, Windows Media Player or Quicktime. Anyway, I had given this computer to someone and recently got it back, at which time I did a clean install of W7. Everything works fine except for my media players, and I don't remember how I solved this before. Would love some help on this. Thanks

I recently purchased a refurbished Optiplex 7010 MT. Core i7 3.40GHz 4GB RAM, 250GB HDD, DVDRW, 7P Minor side issue: I have already ordered the memory to upgrade it to 32GB RAM based on the advice of the store that sold it to me and Crucial.  Unfortunately, if I read the dell-optiplex-7010-manual-en.pdf right.  It can take 8gb RAM but only two of them for a total of 16gb.   Is it possible to utilize all four 8gb DIMM?   If not, the importance of the speed of the graphics has become even more important.
I need to upgrade the power supply and video card to run Adobe software -- Photoshop, etc. Based on prior experience, I need the fastest possible graphics option.    I'm thrifty but not stingy ... if I can get a racehorse for a bit more then I will.
The video card that I'm thinking about buying is the GEForce GT 640 recommended by Dell. Is there a specific version since the specifications also say "(OHGA3/M209N)"? I would prefer to be able to use a card with more memory but still PCIe 3.0 which appears to be much faster than the PCIe 2.0. If there is a better card out there, please let me know.
The power supply is standard. Since this is April 2016, the Dell recommended Corsair 650TX appears to be hard to get at best, Is there another power supply that would work?
Thank you for your help. Much appreciated!
