If you have no plans for a second card the 650W should be sufficient. There's also any extra fans or peripherals, but it looks like you'll be fine.
If you are hesitating because of the cost of the 750W, I wouldn't because you really want to get a quality PSU that can handle any overclocking or expansions in the future. I recommend getting the 750W as it will be with you for the next 5 years.

No 650w is fine for any overclocking. 750w is only necessary for futureproofing against adding a second graphics card. Look for Corsair, Antec, Seasonic, PC Power and Cooling,XFX, or Enermax for top quality.
