You're going to need a 1000 watt PSU. 850 isn't going to be enough, especially if you're OCing.

I would go for a higher power level than 850W, I would suggest going with a 1000W PSU as it will give you that bit of extra power if it is needed and I would suggest getting an EVGA, seasonic or XFX one

No, you are looking more like 1100w

And... adding the third card adds incrementally less capability . Perhaps two stronger cards would be better.

Okey, thx i will go for the 1000w edition!

The 3 770's will use around 225 watts each Oced. You're GPU is like 88 not Oced. You also have fans, LED's, HDD's, and varoius other components. 1000 watts is a good number and it gives a little head room.
