So i bought a RX 560 and the gpu didnt have a vga port so i bought a displayport to vga cable. Before with my old gpu a radeon hd 6570 i didnt have any problems but now while gaming or watching anything in fullscreen my screen goes black from time to time for a couple of seconds. I found a temporary solution witch is to play games in windowed mode. I think the problem is with the displayport to vga cable but i might be wrong.To power my GPU i use a molex to 6pin.

PC specs:
CPU: X4 750
MOBO: FM2 A55M E33
GPU:RX 560
RAM: DDR3 8GB
PSU: unknown brand 500w

P.S. Sorry for my English it is not my first language. Thanks in advance :D

Do you have any more info on the PSU? If it has an 80+ rating or not? The psu may not be efficient enough to power the gpu off of a molex. And just because a psu says 500 watt, that does not mean it will be able to supply 500 watts. I saw in a review on JonnyGuru.com, a psu that claimed to be able to supply 500 watts. It had no 80+ rating, and was from a company i never heard of. It was only able to efficiently supply about 325-350 watts max. More than that and the system started to become unstable. So my point being, the psu is most likely the issue here. I doubt it is the displayport to vga cable, since i know many people that had to use similar cables and never had a problem. Then again, maybe you got a bad one. If you find anymore...
