All you need to do to power up the PSU was to "Ground" the wire. Meaning, connecting the "Green" wire to any of the 6 "Ground" wires from the same ATX connector and the PSU would power up like it was connected to a mobo! That was easy, wasn't it? OK, so that's the end of this guide! Hahaha! Joking! But, that means the extra PSU will be at the "ON" state no matter what state your PC is at, "ON" or "OFF". How about if you want to be able to switch it off?
