PC ATX power supply in a G4 case?

Message #1 - Posted 2004/04/12 - Barton Oleksy

I have a G4 case with a Yikes motherboard, but no power supply at the moment. I thought I had seen a web site that suggests cutting one particular wire on a (cheap!) PC ATX power supply makes it work (the connectors fit perfectly - I tried that much at least, with the power off!). Can anyone confirm that? Is anyone doing it? I can get a 'real' Mac power supply from someone else's G4 parts system for $40, but I already have a spare ATX power supply here that I don't mind clipping a wire or two on.

Also checked to see if the ATX power supply physically fits in the case, and it seems to fit very nicely as well, with at least a couple of screw holes lining up to keep it snug & secure.

Thanks for any and all responses!

Note that they're using a Sawtooth motherboard.

Is anyone doing it?

Not me. Personally, I'd just go with the $40 Mac PSU.

How different is that from a Yikes board, do you know? At least as far as the power lead... I understand that the Yikes board in some ways is closer in architecture to the B&W G3 boards. True?

Sure, so would I, but I actually hadn't found any Mac PS's for this for that little...where wasn't I looking (where I should have been)?? Thanks!
