I know that the Powermac G4 PSU's have issues, so I want to change it to an ATX PSU. I have looked online, and I am confused! I can't find a simple diagram! I know that you cut off the motherboard wires from the old psu and solder them onto the new ATX psu, but do they match up easy, or do you have some wires left unused or end up soldering 2 into one socket? I really don't want a fire, so could someone please help me!!!
