Power Supply Recommendation 2x6970 or 6990

post #1 of 8
Thread Starter 
Hi guys. I'm trying to make a build for my 3x24" eyefinity screens. I don't want to pay more than I need to so I'd like to ask for some recommendations for power supplies for something like this:

i5 2500k

p8p67 pro

CM 212+

HSI Radeon 6950 unlocked to 6970

1333 ram

1TB Samsung F3

SSD


I was told I can get by with a good 750 or 850 but any recommendations on good value psu's?

Thank you
My System

750W would be perfectly fine. You'd be fine on a good 650W unit as well.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207009 is an excellent value currently.
If you'd rather have a modular PSU, then http://www.newegg.com/Product/Product.aspx?Item=N82E16817207003 is an awesome unit as well.

750Watts would be plenty.

Here, it's cheap and it's good.

I don't think it's $99.99 good when you can get better products for the same price. But it's an alright unit.

I'm really thinking about getting the XFX black 750.. Would you guys say it is worth it to get the corsair hx850 for $30 more for possible future upgrade or extra video cards? There is a coupon and rebate for that now. I overbudgeted for my psu and can afford up to like $175 but just wanted to see what you guys think

Rather than the Corsair HX850, you could just get the XFX Black Edition 850W. They perform very similarly and the XFX is always cheaper. It's currently $109.99 after rebate, that's the best deal you're going to get on any 850W unit.
You won't exactly need 850W though, and once you have two video cards in that system, you won't be adding a 3rd except maybe as a dedicated PhysX card (because of PCIe lanes). For that you could grab something like a 9800GT or a GTS 250, low power cards that would be fine on a 750W unit.
