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.

Been looking at these: http://forums.macrumors.com/showthread.php?t=261623 Great job researching, Dan- you don't need me to send you directions. The diagram on Macrumors is what I used with my DA (similar to a Quicksilver). I happened to have some old BW panel switches and the setup delivers as promised, firewire is active and bootable. I don't have an ADC monitor so I can't vouch for that aspect of it but I can see no reason why it shouldn't work. I did this conversion 2 years ago and it is still running strong with daily use, powering 3 ATA hard drives in a RAID 0 array (Sonnet card) + 2 DVRs in a pc mid-tower case. The PSU I used is 525 W, quieter and cooler running than the Mac PSU. --~--~-~--~~~---~--~~ 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.

Dead Gigabit Power Supplies - what to do?
I just confirmed that two of my G4 Gigabits have failed power supplies. I made sure that the CPU cards were bolted down properly, so that there was no grounding failure, and I tried the suspect PS's in a working Gigabit. One of them works if it's kept plugged in for a while before turning on the machine. The other one simply won't start the machine at all. From what I've read, it's not really safe for me to try to fix them myself unless I'm experienced. I called a local Apple authorized store for laughs, and their repair quote did make me laugh. For their price, I could buy a decent G5. Is there any source for inexpensive replacements? The last time I checked eBay, the prices were not encouraging. I know that there's a way to convert a generic PC PS to do the job, but I think it will be too time consuming. (I imagine various little time-wasting fussy things even just to get it to fit it in place, for instance. I realize that some of you love this kind of challenge, but I've had too many of them, and have other things that need to get done, including fixing a Pismo.) I'm just hoping to find a place that will fix it or can sell me a reasonably-priced replacement that I can install easily, plug it in, and have it work. Or find a Gigabit with a working PS and something else wrong with it, so I can mix and match. I'm looking at the Swap List, too, but I'm hoping that someone knows of something else, because I might not find anything there. --~--~-~--~~~---~--~~ 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.
