^ Agree with the above. Avoid if if you can. Honestly a 550w XFX would be a much better choice if one is available to you.
Coolermaster and Thermaltake power supplies shoul be avoided. Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, Antec and Rosewill are all good brands. 500 watts is fine for your build.
