These are the same symptoms my G5 had when it blew the power supply after less than 1 week of use new-from-box. I was able to diagnose this with a multi-meter and a pin-out diagram for the power. I lost about half my lines, I can't remember if it was the 3v, 5v or 12v primarily, but my fans ran, and the lights lighted; but like yours, no chime, no nothing. Mine is a dual 2.3, and for this era G5 there was a "known issue" and an "extended warranty" (after a lawsuit). Mine was 1 week outside the extended warranty group, but I took it to an Apple Store Genius Bar that was packed after the grand opening near Christmas holiday shopping season, and I started to get a little noisy when they said they wouldn't warranty it, and they knuckled under and replaced the power supply, logicboard and both CPUs (this is their standard procedure) which would have cost nearly $900 at their prices, for free. Unfortunately, after the repair they forgot to calibrate the fans, so I had to return it again. I was without the G5 for 1 month, and it cost me over $100 in gas, parking, and tolls; plus about 10 hours of my time to get the "free" repair. If you need a power supply, they are expensive and relatively hard to find, might not be worth getting? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
