I'm trying to find the pinout for this HP AlphaStation power supply, Part# 30-50662-01, Power Supply Unit (375-WATT). I've been looking online for the manual without any luck. I was hoping somebody might have some leads on this. I don't have the computer itself to trace all the connections. I have this spare unit which I like to use at work for the extra power; +3.3V, 40A. I did find out there's is usually a Power enable pin - similar to the ATX power supplies which is switched on by a softstart button on the case. I tried looking on Bitsavers, but I'm not familiar with all of the various model#'s to narrow down the search. If there was a service manual available, then it might have some wiring diagram in there I could use to figure out the pin connections - there's about 4 dozen of these on here - arranged in a molex style block on the back side of the power supply (no cables), 2 groups of 24 pins each, inside a blue plastic shroud.
