[G4] Acard AEC-6280M Boot

[Eric Wood]

I once did something similar with an old AT power supply. It had the  
old clicking power button that actually stayed pressed in when it was  
on, meaning it was completing a circuit, I'd wager. Apple's and other  
ATX power supplies do use some external control, whether in the  
motherboard or in a separate little card like in the B&W G3 and G4  
towers to control powering on and off.

So to put it shortly, I'd recommend finding an old power supply like  
that one. I think you're right in guessing that the new ones need a  
motherboard connection.
