Sufficient?

Is this PSU compatible in this build?

That's overkill. Go for a 600w EVGA, XFX, Seasonic, or Antec.

600w is indeed a better idea, unless you want to go SLI later.

The EVGA G2 Supernova 750W would offer a lot of silence if put in eco mode.

Otherwise you should get a smaller PSU.

A 500W would be more than enough.

With 30 quid off thats not a bad option.. 450W would be plenty for that build, 750 would allow SLI.

A quality 450~550w PSU would power that system. The Rosewill Capstone 550w is a good deal, ATM for $39.99 after MIR: http://pcpartpicker.com/part/rosewill-power-supply-capstone550

 

If you have any plans to SLI, the EVGA Supernova 750w B2 is another good option (based on a cost down platform of the Capstone) and is better build than the CX750M: http://pcpartpicker.com/part/rosewill-power-supply-capstone550

750G2 isn't the answer to everything. If OP wants hybrid fan mode then they don't have to spend all that money for a 750G2 when the 550W XFX XTR exists.
