ok, so the wattage is not as important as the SUMS of the +12V.
Because eventhough those 2 you posted only have 430w they still have enough juice to power it?
just want to make sure, cause this psu stuff confuses me alot, lol.
30 Amps? Well based on the PSU101 thread, you need to do W/V=A right? Well the COOLMAX CP-500T EPS12V 500W Power Supply 115/230 V UL, CSA, TUV http://www.newegg.com/Product/Product.aspx?Item=N82E16817159040
has dual 12 rails at 16 and 18. The max Watts on the 12 rails is 400, so we take that and divide by 12. You get ~33.33 A. Would this PSU (half the price of $120, so its pretty good for budget) be enough? (it even has Actice PFC) I myself have this PSU on my current system (AMD x2 4200 and 7900gt) and Im planning on upgrading to a c2d 6600 and 8800gts 320.
