what can my 650W psu handle?

Hello everyone,

Just a quick question. I'm in the process of building a new desktop.

Mobo: http://www.newegg.com/Product/Produc...82E16813157333
PSU: http://www.newegg.com/Product/Produc...82E16817139020
HDD: http://www.newegg.com/Product/Produc...82E16822136769
CPU: http://www.newegg.com/Product/Produc...82E16819113280

I'm going to start it off with 16 gigs of ram, then gradually upgrade to 32 gigs as funds become available. My only concern is I'm not sure how much power I have left to support a video card. I'm thinking I'd like to put in something like this: http://www.newegg.com/Product/Produc...irtualParent=1. Could that work? Would the psu be able to handle a more powerfull video card then that?
