I was given a Mac quicksilver G4 with the power supply dead , it blew the 8 AMP fuse. I’ll be sure that the caps probably need to be replaced but usually the fuse doesn’t blow unless there is a short. I’m thinking that one of the switch mode transistors went bad. Does anybody have any experience with these, it is the Samsung power supply, the long one with two fans in back? Mike Rosen Sent from: My extremely complicated, hand held electronic device.

The PS itself seems fine, but it's been a while since I looked at it -- other projects have gotten in the way. Will need to double-check it of course.

I have two IIci's with Astec supplies. I recapped both and I guess I didn't clean them enough because both do this funky on/off thing like the power-on-circuit is oscillating. I'd just love to bypass it and use a toggle switch and be done with it.
If you look up the people doing ATX power supply conversions there is information with those people on how to bypass the soft ware stuff. Are you sure the power supply itself doesn't need to be re-capped?
In my case I only did the motherboard, but tested the output voltages.
