Well, your pushing it on the 12V rail side with Amps. The minimum is a 500W with 36/38 amps on the 12V rail. Yours only has 35 amps total on the 12V rail.

It has a 18 and 20 amp max rails but that doesnt mean it has a total of 38 amps. Thats just the max any one rail can pull before shutting down the supply. It has 420W total on the 12V rail which comes in around 35 amps total.

Can you tell me if this one would do it? http://www.newegg.com/Product/Product.aspx?Item=N82E16817159055&Tpk=Coolmax%20%2f%20CXI-600B
