What cpu are you going to run?

 

[Sant]

Sorry, its a i7 950

Your cpu requires 130 watts.

And per EVGA you need a minimum of 550 watt power supply with the 12 volt rail rating of 38 amps and 2 6 pin PCI-E power donagles.

I'd be looking in the range of 750 watts.

I'd agree with Route. A 750W and above will leave you with enough head room OCing. If budget is not an issue, go with a PSU that will allow you to add a second card in the future.

Your PSU choice at this point is pretty much determined by your budget; as a rule of thumb, the higher your budget, the better the PSU you can get.

"Better" defines a PSU with an 80 Plus Gold or 80 Plus Silver rating (versus lower-priced ones with an 80 Plus or an 80 Plus Bronze rating), modular cables, possibly a larger, quieter, higher-CFM (read: better cooling) fan and high-quality internal components for cleaner and problem-free power delivery, as well as a large warranty coverage period (5 years is usually standard for a high-quality PSU).

hey

Quality 750w with at least 58 on 12volt rail will insure you of a quiet operation.


Make sure you buy a quality brand.

Corsair,ocz,antec,silverone.

^, 750W is unnecessary; a quality 650W PSU will be sufficient. I second the brand choices however. I think you also meant SilverStone instead of "silverone".

Coolermaster Gold series and Corsair HX series, best PSU's in my opinion. I think Corsair HX850 is good value and has 70Amps on +12V rail. The coolermaster Gold 1000W isnt much more expensive and has 98Amps on +12V rail but may be overkill for your setup.
