Recommend power supply?

[Losergc]

if my build is to be like this http://pcpartpicker.com/p/36aqh
and i'm thinking of overlocking the card often,should i get a 850W power supply or just a 750W will do?

If this is for gaming:

• ■Don't bother with an i7 - get an i5-4670K.
  ■Get 8GiB RAM
  ■That build can run fine on a 550W PSU (750W if you want to run SLI) - get a good one, from the second link in my sig. RM is not good.

The recommended power supply for the GTX 780 is 600W. But will that actually be enough?

Yes. Yes it will. At most, your processor and GPU will only draw about 350W between them.

With your other components only drawing a minimal amount of power, your computer will only draw 400W at absolute most. And if you buy a good quality 600W PSU (Here's a good list), you should have no problem getting enough power. Just make sure it has a 6-pin and an 8-pin power connector that card needs.

Really, the only way you could need 750W is if you plan on using two of these cards in SLI at some point in the future. (In which case, you're looking at a maximum draw of around 600-650W). If that's the case, again, make sure it has enough 6- and 8-pin power connectors.
