Those will run between $80-120 (US) online in most places.
You can probably get by with less, but, again, the DFI boards do tend to work a lot better when you invest in a good PSU and RAM. Even if it weren’t DFI, skimping on the power supply is a bad idea. In any case, a 500-600W from a quality company (like those who’ve been mentioned) will be plenty, not to mention provide some headroom.
Hey, thanks a lot for the help. I think I’ll go for the Hiper Type-R, just for the little extra buffer on top of the minimum requirements. Thanks again.
