It will be fairly close and dependent on what all your other components are, try using this website they have helped me a lot in the past. http://www.coolermaster.outervision.com/
If you put in components and than hit calculate in the bottom right it says about what power you need to run the system. The gtx 660 runs about 200W on its own.
