There's some very good information in this thread, thanks Jamesbeat for starting the topic 😀

I mentioned previously that I'd also considered this - now I've bought a second Dell motherboard, but I don't have a second dell power supply.

The ATX connector fell off:

This required some careful desoldering with the solder sucker, it seems there's timing / technique involved in getting the grounds to clear out properly:

I checked the ATX pinout with the pins on the ISA connector, which has everything but 3.3v - these all matched up:

So I soldered the connector in - note that the Dell ATX connector has pin 19 of the connector missing.
This is one of the 5v pins on the standard ATX connector, giving me only 3/4 of the 5v lines. I intend to rectify this later using a donor ATX connector, which is on its way from China right now:

With the connector in place, it looks like a standard Intel AL440LX except for that extra connector:

This also required soldering on the front panel connectors, because I don't have the custom Dell cable to spare for this board, getting the grounds cleared out on these was just as bad:

Multimeter, big solder sucker & TS100 with big tip, all the tools required:

Impressive. Who knew that repositioning the PSU connector to a different spot was all it took to make those Dell motherboards work with ATX power supplies? 😮

That's a one of a kind screen I made, the first thing I made long before I had a 3d printer to make things up in CAD. 😀 It uses some plastic right angle plastic that I cut & glued into a frame.
It's an N070ICG with a VGA/DVI/HDMI driver board, along with a USB power input to get 12v.

Go ahead and shift the connector over. This will work great if you don't want to wait for adapter cable.

Cheers,

If anybody needs a PSU from a XPS710 I am happy to send it to somebody. I am done with this shit motherboard and I just wanted the tower to pimp up a medion pentium d.

Hey mate. Hope you dont mind me replying to such an old post.
I am trying to restore a Dell Dimension XPS R450 with a blown PSU. Going to look to move the 20 pin connector along like you did and use a regular PSU.

Did you need to do anything with the auxillary power connector or was the board fine without it?

Not OP, but I know the answer.

You can ignore the aux power connector. In Dell machines its there to supply 12V and other voltages that are 3.3 V which is not accessible through the main power connector. If you move over the connector to have a standard ATX pinout, you'll get 12V 3.3 V from the power connector directly.

I'd desolder it while I'm moving the other one.

Be sure to resolder the ATX connector in the correct position (lock facing the same way it was facing initially, just slide it)

Good luck.

EDIT: sorry for brainfart. In Dell machines the aux connector is 3 pins ground and 3 pins for 3.3 V. My recommendation is still the same: I'd remove the connector. If you leave it there and you later get a PSU with an AT style AUX cable and plug it in, you might damage your equipment since the AUX connector from PSUs supplies 5 V and 3.3 V.

Thanks a lot for the reply!

Looking forward to getting it running. It is totally stock with V550 16mb and an aureal vortex 2 from turtle beach.

Soldering besides it seems a fairly easy modification too so that is ideal.

Correction to my post above: in Dell machines the aux connector is 3 pins for ground and 3 pins for 3.3 V.

My recommendation is still the same: remove the connector.

Apologies for brainfart.

thanks again. I plan to print a warning to place inside the machine to note the modification should the machine ever leave my hands 😀

I'm working on my XPS T500. I'm confident in my soldering skills enough to mod my motherboard, but I'm not clear on the ATX wiring. Is my motherboard a candidate for this mod to use standard ATX power supplies?

Amateur computer nerd. Please send help.

If it has those unpopulated pads next to it seems like it can be modded!
