much easyer way to add ATX PS to iMac - 02/05/06 09:17 AM
Well I was bored so I took the old power supply from my sawtooth and rewired it for my Trayload iMac. I found a way to bypass the power inverter to power on the system. Add a switch to the ATX power supply Green wire and Ground (Black) and connect the brown wire to a +5v (Red) wire. It fires right up. I don't know if it works 100% due to no VGA adapter (one is on order) but the chime sound works when you power it on.
