I've just discovered a neat feature of my power supply! There's a way to instantly turn off the PC - no waiting. All you have to do is connect one of the little red leads to one of the black ones - poof, off goes the power! I was using it as a nice 5V supply for LED testing, and accidently shorted it - It scared the pants off me - thought I'd killed the thing! Fortunately, after unplugging it and reconnecting, it came back fine. Didn't even checkdisk on startup! My new plan is to use an old AT psu for circuit testing - if I can get the thing to work!
