Hi
I have an old DEC Pentium machine that I'm trying to restore. It has a proprietory PSU for the low profile case and I have managed to find one with the right dimensions but its AT and the motherboard is ATX. So the first question is if anyone knows of a way to convert AT to ATX? as I guessing it can't be done. I have the old psu but it was corroded and the board was a mess. So I'm thinking if I get a smaller psu and transplant the innards into the old psu housing once I clean it up. It seems reasonable as long as I keep the board mounted/insulated properly away from the metal housing. Just wondering if anyone has done anything like that and if there's any reason why this may be dabgerous/stupid etc?

cheers
Chris

Look into SFF power supplies, extract the innards and place in the DEC's power supply shell.

Especially HP SFF, the internal PSU is only about 50mm x 50mm and short height. Only room it had is 80mm fan.

Or rectangular PSU

A Pico PSU would do here most likely. You could likely even fit the required AC/DC adapter (laptop PSU) into the old ATX PSU housing.

If you wanted it to look more like the stock PSU then you could probably also fit the PICO into the old ATX housing and use extension cables for 20-pin and molex/floppy.
