According to Phaedrus's PSU calculator, an AMD Phenom II x6 setup + SLI 560 can pull up to 600w. (with overclock). Since you may be pulling close to your rated watage of your power supply, I would do a quick search on your Antec EarthWatts to see what others say about pulling that sort of load on the power supply.
It's not on the recommended list of PSU's, but that doesn't mean everything.

You should be fine.

It'll be just fine. You could have gotten away with the 550w Earthwatts Green unit honestly. Your 650w won't even sweat that load at all.

550w would have done the job. Your 650w is MORE than enough. I've ran 580 SLI off my 650w (for a weekend), and it didn't shut down on me.

Those calculators always give themselves a LOT of head room as suggestions for two reasons....

1. Cover themsevles so they don't suggest what would be just enough and might cause any issues. Even though they ask very specific questions about your CPU, RAM, HDD, other periphials, and over clocking.

2. Sell higher watt PSU's than someone actually needs to make more money.

Minimum 750 Watt can run two 580's SLI. Your two 560Ti's are fine with your 650 Watt PSU.
