build looking like:
i5 3570k with 2x4gb corsair vengance 1600mhz
z77 mobo undecided which.
nvidea gtx 670 with either twin frozr or windforce x3 cooling
1ssd, 1 7200 sata drive
basic dvd rw drive, network card, 5 120mm led fans.

eXtreme Power Supply Calculator Lite says:
Minimum PSU Wattage: 328 W
Recommended PSU Wattage: 378 W

is that accurate, would i get away with something like corsair cx500 watts?

(the corsair site calculater recommends 600w)

The site linked below recommends a 500W for the GTX 670. If it is a high quality 500W like a corsair, then yes, you will be fine. Since you do have the k version of your cpu, and a z77 board, I assume you also plan to overclock? If so, personally, I'd up to at least 600W. Some will say overkill, but that's what I'd do. (I have a 750W powering my system similar to yours).

You'd be fine with the CX500. I have it and I can vouch for it.
