700W is what i would reccomed for this build, personally price difference between 700 and 800W are 10$, so get a 800/850 can never go overboard on a psu. make sure its at least 80+ bronze Cert

Yeah, what Amex said. Don't go for the bare minimum on a power supply, just get a good one with plenty of room to spare. I didn't add this up myself (sorry, can do later if you really need it), but anyhow you will often regret it if you try to go with a budget power supply.

Corsair RM Series 850 Watt Gold-Certified Power Supply (http://www.amazon.co.uk/Corsair-CP-9020056-UK-Series-Modular-Supply/dp/B00FG9FZS2/ref=sr_1_1?s=computers&ie=UTF8&qid=1405297958&sr=1-1&keywords=corsair+rm850)

The most those specifications will use is about 600W. The 750W would suffice, but I recommend the 850W PSU. It is ideal for your specifications. The 850W PSU will allow some headroom for upgrades/modifications (i.e. liquid cooling, fan controller displays, etc.). If you want to add another 780Ti down the road, you may want to purchase the 1000W version.
