Sapphire ATI Radeon HD 7050 2gb black screen problem

I recently bought a new graphics card, the sapphire ati radeon hd 7850, and am experiencing black screens when playing games. Is it possible that the card is not getting enough power?

PC Specs:
4gb RAM
AMD Phenom ii x4 850 3.3ghz
Sapphire ATI Radeon HD 7850 2gb
650w PSU (not sure of the make)
Native resolution 1920x1080
