I dont' know how to do the math to ensure that I have sufficient power. Here is my config:
AMD FX-8150 (with a hyper 212)
Gigabyte 990XA motherboard
8 gigs of ram (at 1333 mhz)
GTX560
Thermaltake W0116RU 750W Complies with ATX 12V 2.2 & EPS 12V version SLI Ready CrossFire Certified 80 PLUS Certified Modular Active PFC Power Supply

I want to upgrade my card to a GIGABYTE GV-N770OC-2GD GeForce GTX 770 2GB 256-bit GDDR5 PCI Express 3.0 HDCP Ready WindForce 3X 450W Video Card

Do I have enough juice to handle it?

Did I ask this in the wrong forum? I didn't see a forum for PSU questions. Or did I not ask the right question the right way? I still a bit nervous as to if I have sufficient power for the upgrade.
