Dell Optiplex 755 Desktop power supply replacement.

Q: Dell Optiplex 755 Desktop power supply replacement.

Hello,
I have a Dell Optiplex 755 that has a stock 280 watt psu, I would like to upgrade this to a 550 watt psu. I know the computer uses a smaller form factor psu and because of that I am having a hard time finding a replacement. Is there anyone who has done this, if so what was the model that fit?
I would love to hear any success stories.
Thank you in advance.

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.

The tower on the left is easy to do, the Desktop you need to shoehorn an aux power supply inside by removing the Optical drive. For the SFF and USFF this is completely Impossible. The other issue is that Full size video cards will not fit into that case so the point is moot.

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.

Hello!
I have an Optiplex 790 DT (i5 - 2nd gen. with 3.1 GHZ) and the gpu power supply on the motherboard is restricted to 35 W. My question is, if I could install a rather modern GPU (GTX 1050, RX 480, etc.), if I hook it up via a 6 pin power connector from my PSU (600 W)? Will that work or cause issues?Thank you for your help!

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.

Thanks,

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...

Hey folks,
Anyone know a good replacement power supply for the Dell Inspiron 546 mini tower (not slim tower)?  It says it is a 300W but from a lot of forum posts/reviews a lot of the replacements don't have long enough cables.  Anyone got any suggestions?

Wasn't sure if this is the right category but I guess it's ultimately a question of hardware...

In case you don't want to read the whole background, my ultimate question is, Which power supply should I look to get to replace the dead one in the old unit?

I just moved into an off-campus house at college and the last homeowners left behind a lot of stuff, including what appears to be a functional Dell desktop PC. At least 10 years old, judging by the available ports on the MB and the other hardware inside. The unit is dead on its own, but I tried connecting the 20-pin part of my desktop's power supply to the old unit and the motherboard seemed to power up (light went on, CPU fan started).

The hard drive and CD-ROM drive didn't seem to power on, but I found what seemed to be a safety button (see first image) which I am guessing prevents those devices from powering on if the case is open. Can anyone confirm this for me? I want to know if anything else in this unit is dead, but it seems like everything was in great shape (not much dust, etc). I don't really want to pump more than like $50 bucks into this thing, as my goal was to use this PC as either a dedicated Linux machine or to host a web site (not expecting much traffic at all, and with FiOS Quantum 75/75 we have more than enough bandwidth).

If the computer is plugged into a power strip, ensure the power strip is plugged into an electrical outlet and is turned on. Also, bypass power protection devices, power strips, and power extension cables to verify the computer turns on properly.

Hi Everyone,
I apologise if this has been asked previously, but i wasn't 100% clear in the other answers to this,
I have a Dell Inspiron 3847 desktop (not slim), purchased in Jan 2015. It has an intel core i5 4460 cpu and an INVIDIA Geforce GT 705 graphic card, 16gig DDR3 ram,
It has always run very quite, but just recently (within the last couple of weeks) i have noticed it making more sound then normal, it's soft but a constant high pitched sound which appears to be coming from the stock 300w psu,
If i wanted to change the psu, what make and model would be compatable?, sorry, but i am not really savy with voltages and figures etc, that is why i have asked purely for a make and model number that has been used in this model before, and would work,
From what i have read on this forum, a few people seem to have had issues with the stock psu after a period of time. Any recommendations would be greatfully appreciated, especially from users of the Inspiron that have upgraded their psu,

Thanks Again,
Mr Anthony

After ordering a few power supplies(H235P-00) for some 760's I have, I got a message that Dell has no more of them and that they are EOL.
After searching around, I cannot find a compatible replacement part and cannot find any more information. I have over 40 of these PC's and it seems that the power supplies are at that age where they are close to failing. I have lost 3 in the past 2 months and I need to make a plan to keep these PC's running. Budget cuts are making it nearly impossible for me to purchase new hardware.


Does anyone have any insight into the status of this PSU?
Is there a compatible replacement that I can use that is not listed as compatible?
Does Dell plan to source this PSU out to 3rd party manufacturers so that we can get compatible PSU's in the future?

I's appreciate any help you could give.

I'm going to install a new motherboard in a damaged Dell Optiplex 740 and I was wondering if I install the mobo in the same way the damaged one was and not changed anything else, will I still have to reinstall Windows or will it boot and run as it did with the old mobo?

A:Dell Optiplex 740 Mobo replacement

If you use an exact replacement Dell motherboard it will work OK. If you use a different motherboard then you have a "different" PC and the Dell OEM OS is no longer legally valid. It is only valid for the PC it was delivered with, or an exact replacement (but you will probably have to activate it with Microsoft).

Another issue, Dells, generally, do not support (fit) non-Dell motherboards (or motherboards for other Dell models). The motherboard mounting holes can be different and the back panel I/O panel on many cases is solid and not an insert like a standard ATX case.

Just about nothing but the original is going to fit that case -- if you really need the upgrade you may do better by looking for a used minitower 9x0 OptiPlex and starting with that.
You can probably go a couple of generations newer than a 960 and come in at or around $100 for a complete used system.

So this is a last ditch attempt at repairing a faulty machine, as I like to exhaust all possibilities before giving up.
The machine in the title will not power up. It has a healthy power supply, which I have tested with the button on the back and also by bridging the green PS switch on pin to a ground pin. The fan on it spins and all 12 volt outputs are functional. However, there is no life beyond that, no light on the power button or any lights on the motherboard. I should add that when connected to the mains, the LED by the button on the PSU is NOT lit, until you push the little test button, but goes off again when you let go.
It has been tested multiple ways, right down to the simple test with nothing connected other than the PSU connectors. There is power flowing through the motherboard, as the fans spin up to maximum and the SATA output cable is live and powered up the DVD drive without an issue. I'm just wondering if this board has simply had it, as I cannot see any other possibilities. I've also cleared the CMOS and replaced the battery to no avail.
Sometimes in the past I've known of circuit boards suffering with 'dry joint', where the solder joints break away from the PCB. Putting said board in an oven for a short period of time (at low temperature) rectified this. Just wondering if this is worth trying or shall I just cut my losses and ditch the board.

You can run any retail ATX power supply in the 410. I would recommend getting a modular PSU so that you only connect the wires that you need and put the others away until they are needed. This will help with not getting a clutter of wires that block the air flow.

Recently the fan on my 600 W Cooler Master Power supply started to make increasingly loud noises. Upon investigation I found that the fan was locking up and then fighting to spin. I tried dusting down the system but had no luck in getting the fan to function properly. So yesterday I went out and purchased a new 650 W Antec Power Supply to replace it. I powered down my system, shut off the power supply, and removed the power cable. With an ESD strap tethered I documented the connections, removed the cables, and replaced the Cooler Master with the new Antec PSU. I then powered the box back up heard it post, figured it was fine and put my monitor back on it.

This is where my problems begins.

My system configuration is as follows:

motherboard: nforce 6801 sli
vid card: 8800 GTS
RAM: 4 GB DDR2
HD: two 76GB raptors in a RAID 0 for my OS
HD: two 500GB 7500k drives in a RAID 0 for storage
PSU: 650 W Antec
OS: Windows XP

When I power the box up all fans are active, the hard drives spin up, the mother board posts normally, and displays the "FF" status on the motherboards LED indicator signaling a normal boot process. The BIOS runs and I see it detect my two RAID stripes and it indicates that they are healthy. It gets to the boot from CD check and goes to a blank screen. It does not progress any further.

I am not of the opinion that the old PSU somehow damaged some system components as the actual power output was fine and my system functio... Read more

A:Power Supply Replacement Help

The only thing I can think of is you maybe unseated something a bit when reconnecting stuff. With the power off of course go through and reseat all the power connections, data cables, and add-on cards.

Any reason you didn't just replace the fan in the PSU rather than the entire PSU? Maybe put the old one back in temporarly just to see if it works still.

I have a ThinkCentre M81 which has been regularly shutting down without warning and then re-booting.A technician saw that the power supply does not appear to be the correct type and suggested that I replace it.The M81 manual indicates that the model is equipped with a 280w power supply.  The Lenovo website lists a 240w power supply as the replacement model for the M81.Will using the 240w power supply cause the same problems?Why doesn't Lenovo offer the 280w power supply that it indicates comes with the machine originally.Thanks.

Hi All,
It’s a sad day… my DELL Optiplex 9020 Micro died last night.
The E93839 motherboard started smoking near the CPU, and then died.
Can anyone direct me to where I can purchase a replacement mother board please?... I have searched online (including eBay) but it seems the Micro motherboard is pretty rare.
Any help is very much appreciated.
Cheers
Matt

Dell Optiplex GX270 with P4, 2.8-GHz, socket-478 processor.

I have a Dell Optiplex GX270 sytem with a bad board (several swollen, bleeding, and bursted caps). I went to Pricewatch.com and did a search for Dell Optiplex GX270 motherboard and came up with boards in this link:

http://www.pricewatch.com/search?q=dell+optiplex+gx270+motherboard

They are all for Optiplex GX270; but, some seem to have different other numbers associated with the GX270 and I am now not sure if I can use just any one of these or if I should choose a certain one of the group,

Example: One says GX270 (FG015), another says GX270 (X1105), and another GX270 (U9268), another GX270 (DG279 and finally GX270 SFF(T7294).

Do these other numbers make any difference? I don't see any nombers that resemble those on the bad board I have here.

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.
Thanks.

So I can't turn on my Optiplex 755 through the regular power button.  I have to hold the power supply test button on the back, and then press the on button.  The computer then stays on, but I don't get any video output.  No BIOS beeps or anything.  Not sure what's going on.  The service tag is
<ADMIN NOTE: Service tag removed per privacy policy>

A:Optiplex 755 only turns on through power supply button, no video output.
