I'm working on putting it all together today.


I also load tested the PSU, with a 1 ohm resistor (actually 2 * 2 Ohms in parallel, 10 Watts each) on the +5 line, as well as the 10 Ohm resistor (25 W) on the +12 line.

Results:

+5v:
no load: 5.22v
w/ load: 5.04v

+12v:
no load: 11.68v
w/ load: 11.87v


The resistors get very toasty, very fast! If anyone tries this, I'd recomend either to keep it short, or get a resistor that's got a very high wattage. Mounting this onto a small PCB will help a lot, and use heatshrinks!


I also test mounted the heatsinks, and using a 6-32 3/8" screw, a nylon washer and a nut, the heatsink is so far electrically isolated. Anodizing...
