650 or 750w ?

[Ehren8879]

My proposed build for January includes:

Overclocked i5-2500K
Gigabyte P67A-UD4
(1) AMD 6950
2x4GB DDR3 ~1.5v
(1) 1TB HD
(1) SSD of some size

There will probably be around 5 case fans in this build. I know Sandy Bridge power consumption levels are unknown, so I've used [H] review of the 6950 to assume possible power consumption.

Their 920 testbed oc'd to 3.6 with a 6950 pulled around 380 watts under load. I don't ever plan to go crossfire or add any extensive array of HDDs.

Do you think I can get away with a 650 watt Corsair PSU. I'm currently looking at this deal

Modular would be nice but not necessary. In the 750 realm I'm considering the http://www.newegg.com/Product/Produ...9006&cm_re=corsair_psu-_-17-139-006-_-Product


650 plenty? I think it might be.
Any better bang for the buck, quality PSU solution I should be considering?

Edit: My other ~650 watt considerations

Seasonic S12II
Antec Earthwatts, True power or Neo

A quality 650 should be fine. Don't forget the 6970/6950 cards are not dual gpu's, so the power demands are much lower. They are only recommending a 500w psu for these cards. Here are some solid psu deals worth of consideration.

Antec TruePower New TP-650 650W $79.99 + free shipping

SeaSonic S12II 620 Bronze 620W $74.99 + $9.65 shipping

I'll probably go with the S12II 620 since modular isn't a concern for me. Thanks for pointing me in the Seasonic direction though
