Can a OEM dell power supply be reused

[Amaides]

Hi, I have an oem dell power supply that I want to reuse in a new build instead of buying a new one. I was wondering if this is a good idea. It is 750w. I have a link to a picture of the specs below.

That power supply will be fine dell are known to use good OEMs for their power supplies and it's topology seems that it's from a modern system the only problem you might run into is some proprietary plugs but it will work

I agree that you should be fine with it if not that old and from what i can tell no proprietary plugs,

onector:
• 1x 24-pin Main
• 1x 8-Pin CPU Power
• 2x 6-Pin PCIe x16
• 6x SATA
• 3x Molex
• 1x Floppy

from an Amazon sale.Keep in mind that it has 6pin pcie connectors,no 8pin, when shopping for a gpu.

 

[obsidian86]

You can get 6 to 8 pin pcie connectors if you have to

 

[Vic 40]

If two 6pin to one 8pin i'll agree,but personally am not really one who likes adapters.

On the left is a 6 pin pcie connector on the right is an 8 pin the 8 pin is just a normal 6 pin connector with an extra 2 pins stuck on

I know but with four +12V rails on that psu is it likely that each pcie connector is powered by it's own rail and i wouldn't want to overload one rail by making it into an 8 pin connector with it's possibly added powerdraw.

Any reallly good psu could power four pcie connectors and they chose to just use two 6pin so i wouldn't push this psu too far.

Yes. That is how these PSU are typically set up. With that in mind, an 18-amp rail would be able to provide roughly 216-watts at 12-volts. More than enough for an 8-pin PCIe connector.

 

[Vic 40]

That is per rail i agree,but if they we're confident they could have chosen to use at least two 8 pin connectors which they didn't,why i wouldn't want to risk it. I mean risk making a 6pin into an 8pin connector.

 

[Susquehannock]

What risk? Both type connectors utilize three 12-volt wires. Think about how a typical 6+2=8 PCIe connectors are set up. Simply unclip the two grounds for 6-pin usage. A lot is made of the 75w vs 150w standards. That lies in the PSU itself, and how it is set up, not the connectors.

 

[Vic 40]

May well be but it's not your risk but the one of the OP your playing with.

 

[Susquehannock]

Physics is physics. That aside. Can say from experience that 18-amp 12-volt rails can handle 8-pin connectors. Have re-purposed many Dell workstation as gaming systems, many with 1060 cards. Plus a couple T3500 with 525w feeding power hungry RX 480. Including the one I am typing this with. Flawless for nearly a year now.

Physically Dell PSUs are a little taller than aftermarket. About 1/2". So be careful. Aftermarket fits Dell, but if you don't have a space between your PSU and the MB you might have a problem. Also Dell make their wiring harnesses to fit the layout of the computers they produce. The leads will only be long enough to reach where Dell put things. So the MB leads might be too short for instance. A PSU that size from Dell is probably from a dual CPU machine and could have an extra 8pin CPU connector instead of an 8pin PCIe. Good PSUs but not designed to be interchangeable, even between Dells.
