500 Watt or greater power supply.
One available 8 pin PCIE power connector and one available 6 pin PCIE power connector.

Here is the Tomshardware.com PSU listing. Please select a power supply that is listed as being Tier 1 or 2.

Anything above 550-600 watts will be enough as long as its a good quality unit. Look Xfx/Seasonic/Antec

Any tier 1 or tier 2 unit of 500w or more from the following list will be fine if you are not overclocking:

If you plan to overclock the CPU or GPU card, then go with a 650w unit. If it's not Tier 1 or 2, don't use it with a machine that has a gaming card or is overclocked. If you think you might a second card for SLI later, you want it to be a 750w unit or higher.

Enter your specs into this and it will tell you http://www.extreme.outervision.com/psucalculatorlite.jsp

^^^^THAT, is ridiculously incorrect. Don't EVER use a PSU calculator. ALWAYS use the hardware manufacturer or MSI/RealHardtechX/Guru3D recommended capacity as determined through testing of actual hardware using metering tools.

yes but they give you an idea of what sought of wattage you need

 

[Darkbreeze]

Not really. Almost every calculator I've seen resulted in a grossly underpowered recommendation. If you take what they say and add about a 100w to it, you're probably ok.

Yeah, I decided to upgrade the gpu so I went with an 850w, which is probably overkill but whatever.

 

[Darkbreeze]

I wouldn't call it "overkill" necessarily. I'd call it preparedness. Now, if you decide to overclock or run a second card, you don't need to replace to PSU to do so. Plus, the PSU is unlikely to ever have to run at loads that are near it's capacity, so it's likely to last longer since it will run cooler, the fan won't need to run as often or as fast so it will be quieter as well.

damn... this thread is still going?

 

[Darkbreeze]

No, it's just the voices in your head.

 

[MarkW]

What voices?

 

[Darkbreeze]

See, there they go again. I think you need a Xanax. Or a nice glass of ..., oops, that's right, you quit too. Well, maybe just therapy.

yes when i did my build i used it and added 100w
