I just realized that the PSU i have is ATX so i found a perfect guide here:http://www.casemodgod.com/mod_test_psu.htm
But my PSU isnt switched so would it just be on when ever i connect thge power to the wall or when ever i power up an opticall device? or would it even start up at all?
BTW, is it just me or are the forums really slow all of the sudden?
If you twist the green and black wires together as suggested in the linked guide, the PSU will always be on.
If you (instead) splice the green wire of the PSU to the green wire of the other PSU, your MOBO will turn them both on and off with the power switch.
You will want to power your MOBO and all fans with one PSU. You don't want your MOBO powered with one, and fans with the other. If the one controlling the fans should fail, your MOBO would overheat.
