My G5 just shuts down and restarts itself. And often freezes up.
Does this sound like a faulty power supply to you folks?
When my G5's power supply died, it was dead, no more restarts. You can
smell a bad power supply, it smells like burnt electronics. You can
get a pinout diagram and test the power with a multimeter set on
voltage. It's bad if any line that should have voltage doesn't. The
pinout is here if you want to test:

G5s are known to have issues with intermittent shutdowns and restarts.
You might look at this for some ideas:

Resetting the SMU might be a good idea:
