I hate to say this, but that is not fixing the power supply but replacing the power supply with a new unit. i was hoping to fix it as mine blew and was hoping to revive it, but not luck on this end by the look of it. :(

Thanks for the clear instructions to replace the power supply. I got my part on eBay for $29 (other online stores are charging $100-200+ for it) to doctor up an old G4, and it works like a charm now.

Thank you so very much for these instructions. On my 733 G4 the blue front panel had to be removed to allow the DVD drive to exit from the front of the machine. I also had to remove the fan to allow the wires to exit with the power supply.

Yet another G4 QuickSilver saved from the electronics recycler! In tandem with an eBay-listed refurbisher of my defunct PSU, it was brought back to life. Instructions were very clear.

Is it normal that after installing a replacement power supply for the PowerMac Quicksilver 733MHZ one of the fans is still running? Not sure which one, but once everything is shut down completely, I just pull the plug to avoid that fan from running for ever. Any feedback is appreciated. That unit still runs under OSX 10.4.11 and Classic.
