    My trusty 'ol G4 Dual 450 just died out on me -- it does not power on. I replaced the PRAM battery (went to Radio Shack) and reset hardware PMU. I even tried switching out power cable. No luck. Is it my power supply? Does anybody know where I can pick one up for reasonable price? Can I use a pc power supply?

    Please help.

    Did you replace anything else? Try the RAM, you might of bumped that on accident.

    You might also try the total power down trick--unplug it from the wall, remove the battery, push the power button to fully discharge everything, then let it sit for a while (as in a few hours). Put it all back together and try again--this has resurrected several apparently dead Macs for me.

    As for power supplies, PC ones can be hacked (changing the wiring around a bit) to work in those, I believe--a quick Google search should turn up how-tos. If you're not comfortable with clipping and moving around a few wires, though, you'll need to find a used one, and that's not too easy.

    Maybe somebody even sells pre-wired ATX-G4 adapters, though I've never seen one.
