On the mobo power-connector from the PSU, there is 1 wire which is green, this is the PSU "turn-on" switch. There should be a black wire next to it which u can use to complete the circuit. All black wires a grounds so in theory, any would do but I would use the one next to the green, 3rd or 5th from the end.
