Which PSU is better for my build?

Hi everyone, i want to ask you something, i think you can help me.
First, this is my specs:
CPU: AMD FX-8320 3.5Ghz
GPU: MSI gtx 660 ti PE 2Gb
Motherboard: ASUS M5A99X EVO
HD: 1.5Tb
RAM: 8Gb (2x4gb)

But i have 2 PSU, the CoolerMaster GX-750W and the Raidmax RX-700AC. Which one is better for my build? or if non of them is good enough, which one do you recommend?.
Also, whats the minimum amps that that GPU needs?, or whats the minimum wattage?

P.D.:Sorry for my bad english

  1. Meh, their neither very great PSU's , but if you have to choose between the two, I'd get the CoolerMaster GX-750
  2. Neither. I would go with something from Antec, Corsair, or Seasonic.

    A quality 550W PSU is enough for that system. Spend your money on more quality, not more watts. Something like an XFX Core Edition PRO 550W.
  4. Neither power supply but Raidmax is one of the industry's absolute worst. Cooler Master slaps a lot of fake labels and phony certifications on it's products - they are not to be trusted. Go with something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
  5. You think isnt safer to run that build with the coolermaster psu? I will see if i can get one from the brands that Deemo13 said.

    No I wouldn't touch Cooler Master PSUs with a 10 foot pole, go with the one I posted or Seasonic is always good.
  7. Thank you, ill follow your suggestion. Probably ill buy this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021
  8. Good choice.
