He needs more than that with two 7900GS.

28-32A would be my recommendation for minimum.

30A would be enough and it's always good to have a bit more than you need

so should i have dual 12V's? at 20A or single 12V at like 30 or so??
post #7 of 14
I personally like single rails. Single powerful rails with a minimum of 35amps. My next powersupply will be this one: http://www.newegg.com/Product/Produc...82E16817703005
It has one rail at 49amps.

It has modular cableing, which has a tendency to fail and cause problems. Get a non-modular design.
