Why would a computer (specifically a #G4 tower) power off when a DVD is put in the drive? I'm trying to figure out what's happening to the power supply in this situation that's causing the behaviour, because it's probably a pretty good clue as to what I did wrong when I rewired it that's also causing it to turn off after running for 15-20 min.
And it's not the drive itself. I swapped in another one just to eliminate that variable. I'm fairly certain it's something wrong with the way I rewired the ATX power supply to adapt it to Apple's weird non-standard pinout.

I do have a 1N5822 Schottky
Comparing datasheets
SK26 60V 2A
1N5822 40V 3AThe voltages on this side of the switch mode power supply are not expected to be much higher than 12V DC. This wall wort is rated at 600mA 7.2VA. The electrolytic caps are only rated up to 16V
Will it work?
