Installed new GPU (EVGA GTX 780) and now the computer won't shut down completely.

Installation was fine, but when I go to turn off the computer it just indefinitely hangs at the "shutting down" screen.

OS - Win7
Intel Core i5-2500K 3.3GHz Quad-Core Processor
Gigabyte GA-Z68A-D3H-B3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel MoB
cooler master extreme 2 625 psu (or something)

Came from AMD Radeon HD 6850, but all old drivers have been removed.

Thanks!

I had a 460w OEM PSU and upgraded to a 600w Corsair PSU. My GPU requires 450w. Cooler Master's PSUs are not very reliable and that GTX 780 is really pushing it. You should upgrade to a better brand 700w+ PSU. XFX, Silverstone, and Antec make very good ones.

But what was your card's required amount and what did you up it to?

My card requires 600 min, I'm at 625
