so i want to use these speakers in my arcade cabinet
lilshawn:
running a PSU with no load on the 5v rail tends to make the other rails low.
12v rail will only be maybe 10 or 11 volts... under load it will fluctuate ALL over the place 9 volts, 14 volts up down ... eventually sideways.

i could use this instead of the psu from a computer?

if anyone could give a quick reply so i can get my purchases set.. would this work to power the speakers?
(it would be alot easier than hacking a psu)

mgb:
You can always power your amp from a seperate source that is switched off of a 12volt relay that gets fired off of your PCs psu.
So then when your computer is powered up, the relay is powered and turning on your power feed for the amp.

Save those for your car, and spend $20 (or less) on some decent PC speakers that are plug and play.
