    Yes it will work. Just ground pin 14 on the ATX connector to make the PSU supply voltage to all the rails, not just the standby, and chop into the yellow and a black of a 4pin molex. Good to go.

    yellow 12v to constant, and black GND to ground, and then for ign. For the ign, just either tie it directly in with the 12v constant (so that when the PSU is on, it is on), or to get the feel of car, get a SPDT switch so that the Shutdown controller can be tested. Good Luck

    nah man, i just read... i have an m2-atx, 120w... there is no way a computer pushes 12v at 10a to the HDD conectors... or does it?

    +5V @ 30A, +12V1 @ 16A (CPU1), +12V2 @ 16A (CPU2), +12V3@ 36A (Graphics, Drives), +12V1,V2,V3 = 66A (70A pk.), -12V @ 0.8A, +3.3V @ 30A, +5VSB @ 3.5A
    Add up the 12v. Yes is can exceed 10amps on the 12v rail...
    Taken from the PSU in the machine I am working on. Only 75% efficient so multiply the total by 0.75 and there ya go.

    i dunno, try connecting it to a 12v on the mobo connector or something, look at the sticker on the ac-dc power supply your using and see what it has to say
