Could you give us some pics of the board?
Iirc many of the Intel boards of the time kinda had several "model numbers", one started with PDA or something?

And don't quote me on this, but afaicr Gateway did not use a proprietary power connector (please correct me if I'm wrong). Or at least not in that era.

Should work with any standard ATX and uATX power supply. I have a Gateway Slot 1 WS440 board that uses standard ATX pinouts. If it used a proprietary power supply it would likely be keyed differently anyhow.

[EDIT]

Intel boards manufactured for OEMs started with "AA" I believe.

Here is a picture of the board.

Unfortunately, that's not the case with the Dell PCs from around 1996 to 2000. They use the same plug but have a different pinout.

Gateway's Slot 1 boards use normal PSUs, so for their (later) Socket 370 boards to use proprietary PSUs would be strange...

Looks like an Intel D815EEA or similar.

Funny/annoying thing was Dell and Gateway both used almost identical Slot 1 motherboards, Gateway went with the ATX standard, Dell didn't.
I'd be 99% confident its standard ATX, wouldn't make sense for gateway to have to stock different PSU's

Gateway is using a standard ATX your safe

Thanks guys, just wanted to make sure.

Just a small update, the motherboard works fine with the standard power supply.

Thanks for the update. I recently pulled one from a working system but had to discard the case and psu. To think stoopid moneys are being asked for these nowadays.
