Enough watts for SLI 960s?

[Solify]

Hello, I have recently built a system with the following components:-
-Intel Core i5 4690k Overclocked @4.0GHz.
-Cooler Master Hyper 212 EVO Cooler.
-MSI Z97A Gaming 6 Motherboard.
-MSI GTX 960 4GB.
-Corsair RM650w Gold Rated Power Supply.
-NZXT S340 White Case.
-Samsung 256GB SSD.
-Western Digital 1TB Blue Hard Drive.

So my question is: Can I run another MSI GTX 960 4GB with this Power Supply and have no problems such as overheating?

Thank you for reading,
Solify

650W will handle both fine.

Ok, thanks for the fast response!

Well, i'm relooking and you're OC'ing the CPU, so, well, i still think it will handle both GPU's, but i would recommend a upgrade to 750W
