I'll be blunt: the Power Supply is junk - don't buy that brand in general, and no matter the brand name the specs on that PSU are not good.
You want to get a PSU that has at least 40 amps on the 12 volt rail (multiple 12V+ rails are good too). That one you selected has a measly 24 amps.... it says 650 watts but any system that draws close to that many watts will fry the 12volt rail. For $55 you can get a far better PSU.
This one will kick the other PSU down the street, is $50 after MIR, and is a reputable brand name product
I agree with Elder. For some odd reason, the Broadway unit puts most of it's amperage capability into the +5volt line, but you need the power in the +12volt circuit(s).
