If it "boots" the rest of the stuff without the 12-pin cable, could be motherboard after all, and nothing to dow ith PSU.
Do like goobergump has suggested, take out the CMOS Battery for like 30 seconds and then put it back on, and re-try.
This sounds weird

Alright, that's a better option then. If you get your friend's PSU to fire up your rig, we could then say you need to RMA that PSU.
If not, I say you killed the Motherboard somehow.
I wish you good luck with your issue and I will stay tuned to this thread to help as much as I can.
