You mentioned you had a repair shop near you. One of the things you might ask them about is how much it would cost just to test your power supply. (I suppose you should be ready with some model info so they know which power supply you are using?)
For the ATX power supplies used in a PC (and I'm guessing now also used in Intel Macs ??) there are inexpensive test devices available these days. You plug the power supply into them instead of the motherboard and see what the go/no-go idiot lights have to say. Unfortunately I doubt you've got that alternative available to you with the PSU for a PPC Mac. The resources at this repair place you mentioned might be your best bet provided they don't price gouge you. -irrational john -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
