[QUOTE="hughvane, post: 743744, member: 56231"] Open up your G5 and sniff - yes, sniff - around in the region of where the power cord plugs in. If you detect a burnt smell, then in all likelihood the power supply unit is history. To my knowledge, there is no internal fuse protection. If you know how to test a psu, ie. power in vs power out, with a multimeter, you may find that your present psu is okay. A m-meter will also show you if the psu is dead. Alternatively, an electronics technician could test the psu for you. For guidance on removing (and by inference) replacing a G5 psu: [url=http://www.sharpeningbeneath.com/g5guide/]Powermac G5 Take-Apart Guide[/url] Where to get another refurbished (and verified) psu?
