Answer
sure!  so its not just me that has PC power supplies laying all over the place huh?  
ok so you said you have 3 power supplies and 2 amps?  You planning on doubling them up on the sub amp for extra current?  This sometimes works but if the power supplies differ at all in their voltages they will use power to fight eachother. most power supplies are regulated nice enough to not do that so you should be fine. Or do you have a cd player that you are runining one of the power supplies with?
Regardless, all you have to do is hook some of the yellows (2-3) from a power supply to the posative on the amp, and some of the blacks (2-3) from the same power supply to the neg of that amp.  to turn the power supply on just short together the green wire in the motherboard connector to any black wire.  to turn the amp on touch another yellow wire to the "remote" wire on the amp.  then its just a matter of having the speakers connected to the amp and feeding the amp some signal on the RCA jacks which can come from anything.  a pc, a cd player, anything.  if you need to adapt from 1/8" headphone jack to RCA, Radioshack has that wire.  If the power supply shuts off when you crank the tunes you can try a capacitor on the power lines to help with peaks.  if it still shuts off, you can add a PSU in parallel but if that doesnt help then you're simply pushing the limits of what can be done with a rig like this.
Anything else I can help with?
