The computer does not see the video card. What could it be?

Question

Iron

A computer came to me from another city. Before this, the computer worked perfectly. I started to collect it, connected the video card - there is no image. The fans spin on it, there is a backlight. I fiddled with it until the motherboard died. Okay, got a new computer. New power supply, new processor, new motherboard and RAM. Only the video card was not enough. Decided to connect vidyahu to a new computer - the same result. The fans are spinning and the lights are on. I brought the image from the integrated video card, went into the BIOS and I see that he does not see it. What could be the problem? Burnt out?

Answer 1

6 pin connected to the video card from the power supply
