Hello,

I have a Compaq DP4000 which I would like to use the PSU from. When I plug the PSU into my DTK Dual-PII mobo I cannot get it to boot. If I plug a normal (new) ATX PSU into the board it works fine.

I know the Compaq PSU works, but I think the wiring is completely different. I'd like to redo the wiring to the ATX header so I can have it function on the DTX mobo but I'm stuck trying to figure this one out.

I pulled the ATX header specs off a Compaq PDF for this model and compared it to the ATX v2.1 standard and some things don't match up.

Also, I don't know whether this PSU would be considered an "EN" or "EP" and there is a different chart for each. A shot of each one is included below, and a push in the right direction would be invaluable.

Thanks!
