http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020 I highly recommend upgrading to that. Corsair power supplies are great and that one will power your setup, plus a gtx 480 and any overclocking you may do easily.
Why would the OP need a 650w unit when a 2500K will push 100w and a GTX480 OC'd on air will be at 250w? Rest of the system will pull 50w.
Honestly, his current psu is enough.
I'm running a gtx 480 at 960Mhz core with 1.25v and a 3960x @4.7Ghz 1.4v. This is alot of wattage I'm pulling here and my Corsair 650w isn't stressing at all. SB-E 6 cores are power hogs and can easily push 200w and more imo. A 2500k takes next to no power to run, so it's an easy call here.
