Hi guys!

I'm planing on building a new rig, but I'm not sure what Wattage to get in terms of power supply. And I've used some of those online power supply calculators but they gave me different results... :s

So I'm planing on getting the following.

Asus P6T Deluxe V2
Intel i7 Core 920E 2.66ghz
XFX GTX295 1792MB (576M) DDR3
Corsair PC3 1600MHz CL9 (12GB)
WesternDegital 1TB 32MB
x2 WD 320gb (in raid 0)
Asus 24X DvD+-RW
Creative SB X-Fi Titanium Fatalty Pro
CoolerMaster V8 Cooler

And if some one could maybe point me a the right brand of power supplies too

Any help would be much appreciated :) 

Thank you

and over clock it to 3.6 - 3.8ghz

According to several technical reviews I looked at a few minutes ago, an overclocked Intel Core i7 system with a single GTX 295 used a grand total of about 330 watts at full load. At idle it was just under 200 watts. This was total power draw at an electrical wall oulet. That means it was total power draw for the entire system with all components. In one technical review the system was easily powered by a high quality Corsair HX620 power supply. Different technical reviews showed slightly different figures but they were fairly close to each other.

A high quality 700 to 750 watt power supply such as those offered by Corsair, PC Power & Cooling, and Seasonic is more than is necessary to power your system.

cpu's an cpu clocking doesn change power requirements to drastically the 850 would be fine even clocked to over 4ghz and an for upgrades over the yrs

When I OC'd my Q6600 from 2.4 GHz to 3.6 GHz, current through the CPU power plug went from about 8 amps to 9.5 amps. Considering the power demands of a complete system, the increase that an OC'd CPU needs will be virtually insignificant.

A solid 550W PSU like an Antec Truepower New or Corsair VX would be sufficient.

I agree with jtt283 - A high quality power supply like the Corsair VX550 can easily power your system.

The general rule of thumb is a high quality 500 to 550 watt power supply can easily handle an overclocked system with any single video card made.

Keep preaching..... But I fear that the choir is all that is listening. I think I'll just give up and start recommending PCP&C 1000w or higher for any and all builds....

550 is a hair low for a highly overclocked i7 and a 295. It would work, definitely, but I'd probably go with something like a 650 just for a little more headroom. A 295 is fairly power hungry.
