I need a PSU to run a radeon 7770.

Will this PSU work? Yes, it is a Coolmax. However it is 80 certified and has great reviews. I know Coolmax is a low quality brand, but this PSU my be an exception. Every brand has good and bad products right?

Please note i'm on a budget.

If the coolmax is a no go how about this coolermaster:

Its 80+ bronze and awesome reviews. Only gives 450w. I feel this may be not enough power for my radeon 7770 and AMD athlon x4 750k quad core processor.

I would not trust that PSU but that is your all. WIth the amount you listed it will be tough to find a high quality PSU.

Spend a little more money and think about 1 of these:

Rosewill Green Series RG430-S12 430W Continuous @40°C, 80 PLUS Certified, Single 12V Rail $49
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182202

SILVERSTONE ST50F-ES 500W ATX12V $49
http://www.newegg.com/Product/Product.aspx?Item=N82E16817256061

Just remember the PSU is the heart of your system, if you go cheap and push it too much you could cause real bad damage to your PC

Agreed. CX430 is better than Coolermaster a bit. And you can get it cheaper on Newegg now. As far as power needs you don't need to be worried about wattage. Your system will draw 250W max and both of these supplies will be sufficient.

Best regards.

To answer your inquiries:


I would say between 300W - 350W.



Yes.



The efficiency of the PSU's ability to convert AC to DC.
