650W Power Supply Enough?

I'm wondering if my Corsair TX650M 80PLUS Bronze 650W power supply will handle my system that I want to upgrade. I'm looking to upgrade my video card from a GT 520 to a GTX 780. I calculated the minimum wattage I need using eXtreme Power Supply Calculator Lite. The minimum wattage I need is 635W and the recommended wattage is 685W, but I don't want to upgrade my power supply if I don't want to. Also, I have had this power supply for around 2 years now with average use. Average meaning it's on for a few hours a day but sometimes left running 24/7 for a few days (usually when I'm downloading something).

 

Will a 650W power supply be just enough for this? I wouldn't be upgrading anything else after the GTX 780 until March/April (2014) which is when I would get a new power supply.

I think it should be fine if you want there is a website that shows you how much power you would need. The website is pcpartpicker.com if you go on it put your build in to the system build area and it should show you on the bottom right or the top right. But otherwise I think you should be fine.

I used to run a 3930K and 2 Matrix 7970 Platinums with a 850w corsair but it pulled about 650 watts from the socket on full load.
