Hi, I have recently bought a Gigabyte GTX 770 2GB and when I run heaven benchmark i find things like shining colorful stars in some parts of the benchmark and also, in some games like ac 4, horizontal lines appear. I haven't overclocked it and i have tested with the serie drivers, with the nvidia most recent drivers and with beta drivers, and all the time I receive the same thing. Can you help me and explain what is happening? I have a Thermaltake litepower 600w

Thanks for your help.

Your graphics card requires a fairly strong psu of about 575w with a 6 and an 8 pin pcie connector.

Thermaltake litepower is only a tier 3 unit on this list, and may not be delivering sufficient power.

Can you test with a stronger/better psu?
