GTX 650 on a 450W power Supply

[HSBATTH]

+12V = 14A
+5V = 34A
+3.3 = 28A

My Question is GTX 650 is 65w CPU and I am not planning to do SLI.CPU Wattage is 75-80w.

Can my PSU handle the system?

The GTX650 needs 20A on the 12V rail and 400W for the total PC.

12 x 14 = 168W, not 450W.

A good 450W - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151124 - has 37A on the 12V rail.
