I'm sure you're finding out that it is nearly impossible to repair or replace a Mac PSU economically. If you change you mind about using a pc power supply you'll find it's not that difficult, I can email directions and wiring diagrams if you like. ATX form PSUs are the same physical dimensions as the Mac PSU, they fit in place easily. The wiring conversion is done by swapping a few wires in a 24-wire extension cable (which is needed to reach from the Mac PSU location to the Mac mobo connection). Instead of a +28V wire you jumper a +12V, meaning that you can't startup from a Mac monitor or boot from firewire. If those actions are important to you there is a way to boost the +12V to +25V but it truly does involve more "time-wasting fussy things" than most normal people are willing to put up with; you might be better off looking for a used G4 and swapping parts from your dead machines. --~--~---------~--~----~------------~-------~--~----~ 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.
