If you look in the manual for your motherboard or the motherboard you are considering purchasing there will be a recommendation for the minimum wattage of power supply that you need. It will be a little hard to find but it's there somewhere. I know from personal experience. And remember when purchasing a power supply don't try to get the cheapest one you can find, get a higher-quality PS with proven reliability. A cheap PS can be dangerous or fail and damage other compliments in your system. There is a very informative and useful article on power supplies here on Tom hardware.

Go for the EVGA G2 750W. It's the best 750W PSU out right now and will give you plenty of headroom to OC. :)
