Which psu?

I am going to be building a PC after xmas and wanted to know what would be my best option, I have a budget of £75 for the psu, my specs for the build are;

Case: fractal design r4

GPU: EVGA gtx 760 SC 2GB

MOBO: Asus M5A99FX pro r2.0

HDD: western digital caviar blue 1TB

Memory: Kingston hyperX 1600mhz 8GB

CPU: AMD FX8320

Any help is greatly appreciated 

Seasonic G 550 or Fractal Design Integra 650W; whichever is cheaper. Both have a low ripple, nice warranty, and high efficiency.

This should be more than enough in terms of wattage and is under budget by a fair bit.

thanks, a corsair cxm750 is only £10 more and will give me enough if i ever want to go down the sli road is £65 worth it, i dont really want to spend more than £70 on the psu
