What do you guys recommend?

I want to get an MSI Twin Frozr 7950 and I am wondering what Wattage PSU I should get? I was going to go with a 750W but I notice some people are running fine with 500W or so. What should I get?

For reference, this PSU will be powering 8 120mm fans in my Antec 1200, a Corsair H80, and a Mobo.

Let me know, thanks!

If you recommend a specific PSU, let me see it. Hopefully it wont cost me an arm and a leg.

Generally, you will be fine with a high quality unit that has the necessary PCIe connectors, that's 2x 6-pin for an MSI 7950 3GD5/OC. Any reputable 500W unit has those.

However, assuming a heavily overclocked CPU (why else would you have such high end case and CPU cooling ), and also factoring in the huge overclocking potential of an otherwise low power 7950 (800MHz to 1.1GHz or more) , it's a good idea to overshoot the wattage a bit. I would recommend around 600W for a single GPU mobo, 750W for a dual GPU mobo.

Here are some good bang for buck options.

PC Power & Cooling MK III 600W $70 ($50 AR) - 80+ Bronze, modular, 5-yr warranty, made by Seasonic
Rosewill Capstone 550-M $76 AP - 80+ Gold, modular, 5-yr warranty, made by Super Flower
Rosewill Capstone 650W $80 AP - 80+ Gold, non-modular, 5-yr warranty, made by Super Flower
PC Power & Cooling MK II 750W $90 - ($70 AR) 80+ Silver, non-modular, 7-yr warranty, made by Seasonic
OCZ ZT750 $100 ($80 AR) - 80+ Bronze, modular, 5-yr warranty, made by Enhance Electronics

edit: personally I'd choose between the two PCP&C units.
