My Power Supply Help!

I don't know what wattage power supply to get right now! Someone plz help I don't know if I should get 850W or 750W. I don't plan to do a huge amount of overclocking. Here is my build http://pcpartpicker.com/p/HAsR

 

I would not recommend overclocking on that motherboard

Why do you recommend not doing an OC on that board? Heard bad things or do you have experience with it?

 

750W should be plenty.

 

I was told to stay clear of it because it has a 4+1 power phase but thats only if your overclocking the cpu and ram other than that its a solid motherboard

650w will be plenty but I reccomend 750 if you have some dough to spare on it.
