What wattage PSU should I get for a AMD FX-8350 and a GTX 780 TI?

[HowlSpice]

Hey guys, I was wondering how much watts do I need for a AMD FX-8350 4.0GHz 8-Core and a GeForce GTX 780 Ti 3GB that can fit in a Rosewill Blackhawk-Ultra. This is my first time building a computer, so I don't know much.

For a single 780Ti get 600W-650W
