Will my power supply be enough?

[FinalJenemba]

Thinking of upgrading to a XFX 6950 1gb from my 8800gts 512 soon, and im wondering if my power supply will be able to handle it? Its an Antec 650 watt, this one exactly: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371015

Other components are: i7 860, GA-P55A-UD3, two 7200rpm drives, and a bluray drive. Only going to be running one card, no interest in crossfire at all. I have a feeling ill be fine, just wanted to double check. Thanks!

At one point I had a Q6600 @ 3.6Ghz and a 4870x2 with a 4850 in Triple-crossfire all running off an Earthwatts 650. The power-supply is no slouch, you should be fine.

Easily, you can get away with an i7 and an HD6950 off a 430W PSU (not that it's particularly recommended)
