I'd rather not waste $40-50 on trying a new PSU, not to mention the week

I didn't spot that you had tested the PSU on the bench? If you plug in
the power then short PS (Pin14) on back to one of the (black?) common
wires (say Pin15) with a straight paper clip?

If it runs up than it may either being overloaded by something within
the PC or simply faulty .. ?

It isn't enough that the power supply turns on.
There has to be standby voltage to the motherboard, and when
it's on, the pwr-ok has to be on as well as good 3.3, 5,
12V, and perhaps -12V outputs.
