I used the newegg,extreme psu, and psu watts and 12 v calculator, for a system based on a q6600,gtx 260,2 dvd-rw,3 hard drives,a regular desktop mobo, 5 usb devices, 4 fans, 2, pc1, and 1 pce-1, i receivedd the following results, newegg pus cal-663 watts,extreme psu-387 watts, psu watts and 12 v calculator- 413 watts. Any clue as to which of these is more accurate?

The system you mentioned will actually use only about 387W at the outlet. Newegg is recommending that you get a decent 650+W PSU. Any good 550W (ie 550VX,etc) PSU can power that build fine

@OP: Use this calc: http://extreme.outervision.com/psucalculatorlite.jsp
I ran smiler numbers to your system, with a OCed Q6600 @3.4Ghz, and I got 395W. This is the MINIMUM wattage you will need.

The Newegg calculator is based on the Extreme psu calculator, why the 2 numbers would be so different is beyond me.
Whats the 12v calculator that you speak of ?

This is my favorite as it give's an idea of actual use, not a wattage reccomendation.
Using crude math and a Killawatt meter, the aanet calculator is close, and is within 3% of the readings that my Odin Gt throws out.
