Yes, it should be enough to run your card. I ran my 780 Ti with a 500W Corsair before and it ran fine.
-edit: my bad, I was thinking of my much older systerm, but I did run my gpu with a 700W Corsair.
If you want, you could check http://www.extreme.outervision.com/psucalculatorlite.jsp.
Take note that the recommended wattage shown there would be when everything is at maximum load.
