a 750 watt psu will be enough for your system ...250w TDP x2=500w processor 88 watt.......plus other parts say 100 watt......so a good 750 watt would be enough but hence you are going to oc the processor just to keep it safe get a 850 watt psu so that u could have some extra headroom......http://au.pcpartpicker.com/part/evga-power-supply-220g20850xr but if u can spare some more money then get this http://au.pcpartpicker.com/part/evga-power-supply-120g21000xr
its a 1000 watt psu and it comes with 10 years of warranty so that's a long time......

If you cant afford that than i would go with the cooler master v750 you mentioned above. Its good quality and 750 watts should be enough as long as there is no serious overclocking on the gpu.
