I would get this : http://pcpartpicker.com/part/seasonic-power-supply-s12ii520bronze

 

This would be about the same price but better than the cx though :http://pcpartpicker.com/part/evga-power-supply-100b10500kr

It's cheep, reliable, I've used it in 6 builds at this point and even own one to state my point. If you want modular stick with that corsair cx powersupply there

I would recommend the Fractal Design Edison M 450w: http://pcpartpicker.com/part/fractal-design-power-supply-fdpsued1b450w

It's a Seasonic G unit internally with a FDB fan for $45 USD shipped. It is superior than the Seasonic M12II-B 530w, EVGA 500B, CX500, etc.
