Got the new power supply in and just as I'd feared it still doesn't work. I get the 1 long beep, 3 short beep error (memory) and the onboard diagnostic gives a 8.7. error (check CPU core voltage). It could be the motherboard but at this point I think I'm just going to bite the bullet and build a new machine.
Yay!
