Really the best thing you can do is try and find a purely 12V - 13.8v PSU. with a standard Comp PSU you need to dumy load the 5v to get to 12v on the 12v rail.
That can be sort of a pain.or build one custom ( or have a friend or someone who knows electronics damn good to make one) Why cant they just make some 120VAC pelts?

hehehehehehe or just a nice big 220V 100A Pelt

you could cool yer office building with that beyatch heheheh
