PC boots, but no video

[RoGearLTU]

Hello,

today I've installed Gigabyte GA-Z68AP-D3 rev 2.0 mobo. I'm using it with Intel I5 3350P and Asus Radeon HD 7850 2 Gb. My PSU is Qori 500 W (I know it's not perfect). When I turn my PC on, it loads, but my monitor shows me black screen. I tried different monitors and cables, but nothing worked. Do you have any ideas? Any help is welcome. Thanks.
