Power Supply (3.3VDC, 60A & 5VDC, 74A)

Just saw this on ebay. Not sure but this might be good for driving some low voltage, high current IR diodes. It's cheap. More details here if anyone is interested:

Looks great! Unfortunately, I'm fresh out of 72VDC 12A wall adapters to power... the power supply with :-/

A few $15 computer power supplies in parallel is another option.
