Power Mac G5: how to repair a broken PSU?
Give it to a friend who knows a lot about electronics and hope he
can fix it!
I just wanted to report back: he fixed it!
A fuse was blown, possible due to a peek of overvoltage. Anyway, he
used his
very expensive multimeter and found out what was wrong, ordered the
parts,
replaced them, and I then put it back into my Power Mac alloy case.
I had the system board connected, just in case the PSU would blow
up again if
there were no load on it. I heard the “click” again, which hadn't
worked
before, so I was hoping for the best, but still fearing the worst.
So I
continued to put all back to it's place, all the fans, air flow
deviders and
the processor with its huge heat sink.
I cannot tell you how reliefed and happy I was as I heard the chime
after
turning it on again. As there was no hard drive installed yet I
went straight
into Open Firmware and saw the picture of black text on a bright white
background on the screen – so everything seemed okay, from system
board with
memory and processor down to the video card!
It's now running Mac OS X 10.5.8 again as well as my favorite Linux
of them
all: Gentoo, in its all 64-bit flavor! I love it: 16 GB of RAM!!!!
Anyway, all expenses were the parts plus shipping for about <15.00
€uro. Much
better than an also used PSU for around $200.00 or so, excluding
shipping
costs!
Thanks to you all for your help!

Thanks for your update, I too have a PM G5 and did not know they have
any fuses, I'm sure going to find it in cae I have the same problem
some day.
