Need help with PSU.

Hey so I am about to order parts for my custom built pc, but I am not sure what power wattage supply I need for it. Now ofcourse I have done some looking into it but have gotten different replies from everyone. So please if someone can tell me a safe Wattage to get I would apprecaite it.

I will also be overclocking the cpu!

Western Digital 1TB internal Hard Drive - Caviar Blue (3.5 inch)
Corsair Obsidian 750D Black Full Tower case Aluminium Steel with Side Window 3x140mm Fans USB 3.0 E-ATX/ATX w/o PSU

For a system using one GTX 770 it is recommended to use a 575W PSU according to here:

However, their recommended wattages do not take into account ANY overclocking, so I would add 50-100W to their recommendation. Also I recommend getting a quality PSU from a top tier company such as Seasonic, XFX, Corsair (EXCEPT their CX series) or Antec.

4670k OC: ~170 watt
GTX 770: 218, with OC probably 280 watt

So a decent 550/600 watt psu is sufficient. For example, Seasonic m12ii 520 or XFX 550

I wouldn't get anything less than a 650W PSU myself. XFX makes a good one:

http://pcpartpicker.com/part/xfx-power-supply-p1650xxxb9 (semi-modular)

or any of these would do (I'd avoid the top two Corsair CX ones):

Erm few different answers here, I had a 600w picked out initially but I think I will now go with the "Corsair RM650" since its fully modular and cable management is important for me. Hopefully that will be good enough. Also anyone had experience with evga superclocked nvidia cards? are they worth it or is there any company that makes the card with better cooling or something? thanks
