p3 connector on compaq AT power supply

so this older Compaq power supply which died looks like an At with the two 6 pin connectors but there is also another 6 pin that goes into the motherboard, connector is labled p3. wondering if this is something to support the power switch on the front.

unlike the other AT power supplys i have, this one doesnt have the cable coming off as a switch.

ok hope that makes sense

What is this extra connector for?

what colors are the wires on the p3 connector? there are three wires right?, it could very well be the switch.

3 orange, next too 3 black.

the thing about compaq is thier older systems came with PSUs that where wired diferent than the industry standard so that they onlyworked for the oem systems with thier own boards. i have heard of several peoples comps catching fire when theyinstalled new PSUs into old compaqs so be carefull

I have about a dozen of the deskpro's myself. some have psu->switch some dont. and basically when one dies... I scrap the comp for parts.. disassemble the psu for the wires and fans.. and into the trash the rest goes, and I dont look back. because there's no garauntee you can find one that will work. thank you Compaq for another pile of proprietary crap

as thorilan said, be careful replacing stuff.
