Q: How do I install a power supply on an OptiPlex 755 mini tower?

Hello, I bought a new Dell power supply a few weeks ago after I got the blinking amber light of doom I had managed to replace the power supply a few years ago, however in my haste to remove the old supply I forgot to take pictures of where all the cables go and now I am completely lost. I have tried plugging it up but I keep getting a message of "drive one not found Serial ATA and SATA1. It's got a lot of cords that I don't remember on the old power supply labeled from P1 through P9. If anyone could give me a simple explanation of how to plug these cords up I would really appreciate it because I don't want to have to buy a new computer. Thank you very much

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Will any ATX Power Supply fit in the 990 MiniTower?
The system comes with 265 watts but I'd like to install a more powerful supply so I can upgrade the video card to whatever I want.
On NewEgg, the sizes of the various power supplies seem to be slightly different dimensions than the Dell Optiplex 990 supply. 
Plus, Dell doesn't leave any margin for error in replacing with the exact same dimensions as the original equipment. They have all this aluminum and such preventing even a few millimeters difference in size with the replacement.
I prefer a Corsair Gold 80 Plus.

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 wouldn’t fit in the mini case – 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 wasn’t enough to power my machine and to order a 210W power supply correctly sized for my chassis. Gee, thanks! First of all, they don’t 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...

I'm troubleshooting a clients computer that does not get a display on power up.  The user was turning the computer off and back on until the video finally displayed. 
Steps Taken:
Since the computer was powering on and I did not hear any beep codes and the logs only showed unexpected shutdown (powering on and off).  I enabled remote desktop and had the user call me the next time it happened.  Sure enough I could remote in the the computer but they had no display.  Remote restart typically not resolve it.  If I remotely shutdown and the user powers back on it typically did resolve the issue.
This is a dual monitor configuration - 1 DVI (primary) and 1-VGA (secondary)  There are no adapters in place.  The original on-board was using a display port to DVI adapter.Windows 7 Pro
This configuration has worked fine for about 3 years.  This all began about 2 months ago.
Any ideas or known issues with 9020.

I own a Optiplex 760 Mini Tower. 
I found out that I have a 0G214D Motherboard. Unfortunately I still can not find out if this means I can upgrade to a Quad core. Can you please tell me if this is the case and which CPU is the most powerful Quadcore I can use? And if not wich of the Dual cores I should use. BTW, i use an Nvidia  GTX750ti using 60W.
Thank you and all the best

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.

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.

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.

A:Power supply bigger than the tower - frustrated by HP PSU tower

If the power supply will physically fit your case, it should work fine with your computer. Will the extra 10mm interfere internally with anything inside the PC?

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.

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 120mb 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.

Hi ,
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 .
Hoping to hear from you soon .

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

I would like to upgrade the graphics card in my Optiplex 990, can anyone please let me know if there are any recommended PCI / PCI express cards that are known to be compatible with the slot power rating of the system board.
The PSU is not an issue as I upgraded the shipped 240W PSU for a Corsair HX650 with modular cabling so I have got enough juice for the card. Its the motherboard slot rating and any other factors that will impact on choice of upgrade card that I am not sure about. I tried to locate some documentation on the support section of the site but kept getting error messages (servers screwed up on weekend?)
If there is a technical document that gives the ratings for the PCI slots and what can be shoved into them I would be grateful for a link?

A:Optiplex 990 Mini Tower - Options To Upgrade Graphics With PCI Card?

You need to get a PCI Express x16 video card not a PCI.  If you have upgraded to a 650 watt corsair, then you should not have any limitations when you install a PCIe X16 video card.  It should configure to provide 75 watts and additional watts can be provided through the PCIe power cables on the power supply.

I have two Optiplex 755's that I have upgraded with 8gb RAM, faster processors (from suggestions on this site) and SSD drives.  I have Win 7 64 bit on one and win 10 64 bit on the other.  They both have BIOS revision 22A and the latest chipset drivers that I can find here.  They both  seem to be running just fine, with no bangs in Device manager.  I wanted to upgrade the video card to one that would support 4K resolution on my new Samsung TV.  I found what I think is the lowest power card made that will do this, the XFX card using the Radon RX460 graphics processor.  I installed it and got a code 43.  I can not find the specifications for the 755  mini tower power supply.  This card needs 400 watts.  
if, as I suspect, the PS is too wimpy, and cannot be changed out because it is proprietary, does anyone know of a graphics card that will work and still support 4K resolutions?
Thanks, Steve

A:Optiplex 755 Mini tower throws code 43 for new graphics card

Be careful - many of the newest generation of Radeon and GeForce cards require a system with a UEFI firmware your system does not have.
The power supply in the 755 minitower will not be anywhere near 400W -- but the lack of UEFI will render the power requirements a moot point.

I have a 5040 mini tower i7-6700. Manual in Specifications/External Connectors section there is a Parallel feature "25-pin connector (optional)".   I was hoping that mean I could plug a cable onto the motherboard  with a 25 pin parallel connector.  Have done that before with other motherboards.  But looking at the mobo, I see only two unused connectors.  One is labelled USB - INT.  The other label is unclear. 
Does the motherboard have onboard parallel support?  I would prefer not to install a parallel port card in the PCI slot.

A:OptiPlex 5040 Mini Tower optional Parallel support?

The documentation must be incorrect. I do not see anywhere on the motherboard to plug in a 25 pin parallel port cable. The internal parts page doesn't even mention 25 pin connector?

I'll try to be as terse as I can to help:
0. [Assumption here is that next step is to create the Optiplex 7010 Mini Tower Resource disk or USB key from ISO file]
1. Had multiple BSOD's.  Minidumps showed from all over the place.  Reinstalled Win7Pro.  BSOD's stopped, but...
2. Device manager shows missing "Universal Serial Bus (USB) Controller" driver:

3. The dell drivers and downloads page driver search utility identifies some drivers (including a chipset), I've installed them all (including BIOS to A24), but the above device *still* shows up missing.
4. When I use the Intel driver downloads, I got an immediate BSOD when it tries to scan the system (but not the first time).  Minidump looks like this:  (I'll gladly upload minidump itself if needed).  Note: I suspect that this is a possible red herring, because Intel drivers come with the caveat that they are *before* customizations by dell are made.  In any case, as near as I can tell nothing was installed by the Intel driver. Minidump:

Any help would be greatly appreciated as both I and my family are incredibly frustrated with this and I'm afraid that the frequent BSOD's will come back!

Got a store-bought Gateway SX-2800 model which is a mini-tower. Upgrading the video card, and as a result I am also upgrading the power supply.

Being a mini-tower, will it definitely need a specialized power supply, or will a standard PSU work?

If it needs a specialized PSU where do you suggest getting them and how - would I take the dimensions of my PSU and then talk to a manufacturer? Or would buying a new case along with a standard PSU be cheaper?

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

Your spare 500W power supply likely DOES NOT HAVE sufficient 3.3v/5v power and therefore will not work.  If you do not use the performance copper heatsink it will work but the fan will be running all the time.   The Copper heatpipe heatsink is the same as the GX620 heatsink. HEATSINK D9729  SHROUD J9761

I have recently bought a New tower( a super tower) a new power supply, 500 volt ATX 2.0. I have tried two motherboards and I can't even get to BIOS. Would this possibly be the CPU? Keep in mind that I tried the bare minimum took out everything except the video card and the power to the motherboard. Any suggestions would greatly be appreciated. Unfortunately I can't remember the exact type of motherboard, as I am away from home at the moment.

Ok so I just recently got a Dell optiplex GX 755 PC that has- 
*Intel core 2 quad processor 2.4 GHz
*8GB ram
*320GB hard drive (kinda small i know, i'm looking to upgrade that as well)
I'm posting this here to see if anyone knows mainly what graphics card i could get that would make my PC gaming friendly. It doesn't have to be the most amazing stellar quality card out there since iv had (some) people tell me that you cant upgrade these PCs much. But just some good quality advice on the subject and maybe a recommendation on what card brand to get as well as the specs for it. Also a recommendation for a video card would be greatly appreciated as well. Sorry for my ignorance on on the subject, i am new to the PC world. I ended up having to get this computer in a pinch because I am a small time graphics design artist and my laptop died, and I had orders coming in. I'm not looking for a quick fix to the problem so even if anyone has a solution that may take a bit or quite a few steps to get underway, the help is still greatly welcomed! I am hoping if its at all possible to make a good situation out of this and maybe build this PC to fit my needs. Thank you to anyone who can help :)

A:Graphics card & video card for a Dell Optiplex GX 755 (not the mini tower!)

There are no stellar or even really good low profile fanless 25W cards.  ASUS EAH 5450 has been used in Desktop and SFF.  USFF Cant use anything because it does NOT have slots.
