Question, welcome to Sevenforums!

Find one labeled as 80+ power supply, and the minimum would be 800Watts. I would go with 900W

Get a Seasonic if possible. If not, then XFX or Corsair.

The last I heard, 600 or 650 is plenty for any single video card system. But people buy more watts than they need all the time.

I agree with ignatzatsonic on this one, a 600-650 watt power supply here would be plenty. An 800 or 900 watt power supply is simply unnecessary for a build like this. Unless you are going to run 2 high end video cards, you don't have to do anything over 750 watts.

Ok thank you for all answers

I will be going for 750W Because Im going to have crossfire I guess - But one more question ! What is the diffference between Sapphire Radeon HD 7950 and Power Color Radeon 7950 ? - I saw some price changes between them thats why I went for sapphire !

Different manufacturers. Same video chipset. Design of card, the cooling, # of fans, etc could be a little different between the 2.

You also might be able to save a few bucks by getting the latest version of the CoolerMaster Hyper212+....the Evo, I think it is called. It consistently scores as the best air cooler, and it's under $25.

Oh ty! - Is it better than the one I chose?

The Cooler Master V6GT you chose might cool a little better, but it may be unnecessary in your case. It has 2 fans and is very large and more expensive. The Hyper 212 is a fine cooler and better than anything else in its price range.

Are you sure your chosen cooler will fit in your case and have no clearance issues with your chosen RAM? If that RAM has heatspreaders, I would be concerned that it might not fit underneath the cooler.

What does "better" mean to you? Quieter? Cheaper? Heavier?

I wouldn't spend as much as you are spending on a system without getting an SSD.

You also may want to get a couple of case fans. I'm not sure what fans come with your chosen case, but they may be inadequate or unnecessarily noisy.

Will it be good for overclocking ?
