650 Watt enough for 2 R9 290x’s

[cja711]

I currently have a Corsair vs650 and I am on the hunt for a graphics card and I have found a deal for 2 R9 290x’s in crossfire.
Is my power supply going to be capable of running them both or am I going to need to change power supply?

I wouldn't even recommend running 1 290 on a lower quality PSU like that VS, let alone 2. For 2 290s you need a bigger and better quality PSU. Exactly how big depends on the specs of the rest of the system.
