Probably not, I'd recommend at least 850W, preferably more.

100% the answer is no , you need 850w minimum.

No. the regular (non superclocked or anything extra), evga recommeds 250 watts each. plus the wattage from your cpu. you probably need a pretty good one not to get bottlenecking, you really arent leaving yourself with headroom getting a psu that low wattage. even if you get gold. 850watts or more should be fine, but if you really want safe room and dont mind a higher electric bill, go 1000 watts gold rated like the evga supernova G2

Try using this tool:

It is FREE for PERSONAL use and will give you a fairly accurate picture of your power requirements.

On first guess, I have to agree with the above posters. 850w it going to be your starting point, with 900-950w recommended for a little overhead.

850W is minimum like I stated above , I would actually get 1000w if it was actually putting the components in a build.

The electric bill wouldn't be higher with a higher watt PSU. An 850W and a 1000W will use the same amount of power. The electric bill's amount will depend on the efficiency of the PSU. So you could expect a higher bill with an 850W bronze PSU than you would with a 1000W Gold. But even then, the difference in the electric bill would be minimal.

jimthenagual. I was not comparing an 850W bronze. I forgot to mention a rating for the 850W, but i mentioned going with gold rated 1000W, so I was comparing the 1000W gold and the 850W gold, but thanks for clarifying because it was a little vague. it might not be that much from month to month, but added up it might be a few hundred over the life of the psu. either way, someone building a dual 780 system probably isnt worried too much over the additional energy bill cost.
