I don't know the exact numbers, but I think the power required to boot a
G5 tower is pretty huge, much more than normal use.
It may be high but it isn't THAT high

No, just resetting it doesn't. If there is something wrong in the PMU
it might.
After further research on PMU reason code -122, it came to light
that *external* power considerations might be causing an issue. So I
unplugged the G5 from my power strip, and hooked it directly into
the wall in a different outlet. I was then able to boot from
whatever media I like, with whatever disk in the drive I like. I was
also able to rip and transcode a DVD without any problems. So the
problem seems to be either a) the circuit is overloaded (it has 2
other PCs on it) or b) my power strip is bad. Either way, it's a lot
cheaper to deal with than a new PowerMac PSU.
If the strip was overloaded the circuit breaker would have tripped. If
there was something wrong with the strip you would have likely seen
other symptoms.
More than likely what fixed things was pulling the plug and plugging it
back in again. There are some problems in computers that only get
cleared by completely disconnecting power.
Pulling the plug was SOP in the iMac G3 labs I worked in.
