Using the eXtreme PSU Calculator v1.3 I come up a recommended PSU Wattage: of 400-425 watts.

I have 2 psu's i'm looking at, can any of you suggest which one is better, or suggest a different psu all together.

Note: I would also like atleast 36a on the 12v.

Too many posts to count on psu recommendations.... If the psu calculator is saying 400w then get a 500w for future considerations.

The antec tpII at 550w and $90 on newegg is a better bet.
