Quoted from atrainn:Oddly I decided to try the ATX power supply method today and for whatever reason I cannot get the AXT psu to boot when it's plugged into the sound board. It will power up fine when it isn't plugged in though, so nothing is wrong with the jumper I have set to make it power up automatically.
you jumpered the green wire to ground (black)on the ATX PSU?
and you have connected ground, 12v, 5v and -12v to the soundboard?
The ATX PSU is known to work?
