For a GTX 275 and Nehalem i7, a good model that is about 500W to 550W is what you would need.

So if totalz uses it, then we have to make sure he uses it correctly. There are at least a half a dozen very critical options/settings in this calculator that must be set correctly.
By the way, here is the original. The one you linked is a copy.
I'm just worrying about the 5V rail, according to SATA and molex spec, the SATA hdd uses 5V and 12V. So I just want to make sure the amp is enough on 5V. And then what does the ram uses, 5V or 12V? I mean it's a total different story alone in OC with 3 dimms or 6 dimms. Am I over-thinking?
I know these PSU calculators, thanks TwoCables for the original link. Unfortunately, only the pro version supplies what's needed for 3.3V and 5V rail.

Is it true that if amp from 5V rail is not enough, then the extra can be drawn from 12V rail?
ps. not in Aus anymore, hence the Asian OEM brand.Edited by totalz - 8/20/11 at 7:58pm
