    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!

    Yeah I accidently shorted the 5v on the side of my hd cage :eeek:
    my heart started beating when it instantly shut off. The hdd next to it stopped working, but it was still under warranty ;)
    everything else was fine though

    done that more times then i can remember.

    never any damage except for once, and all i had to do then was replace the fuse in it. funny thing is that the psu i use is the only one that ive seen with a fuse (even though its only a weak gateway oem)

    with my old AT psu, instead of turning off, it stops power running to everything, but the PSU keeps running, and a little buzzer goes off (or maybe its just the electronics groaning).

    I've been playing with an old AT one too... great fun!

    It absolutely refuses to work with no load... sits there buzzing at me (not a good sign!). So I soldered a resistor to a LED, heatshrinked it all and plugged it straight into the FDD power. Then I soldered a 9V battery snap to the 5v line (I'd cut a molex off to use for something else). Now I have a great little PSU, with a power light and a convinient 5v supply. It still freaks me out to use it though... not a great fan of electric shocks!

    happened to me too when I was testing my dimmers... a leg of the dimmer touched the case and poof! everything stopped...

    lucky that I am, everything worked again after:D

    that's how I learned to put shrink tube everywhere!:lol:
