Faulty gpu?

[quakebo]

I have a old xfx hd7950 Double Dissipation ghost gpu and when I plug the two power cables into the gpu my pc turns on then turns right back off again but if I do not plug the power into the gpu my pc turns on and stays on.


Any ideas what could be wrong?


My specs are

MSI b550 mpg gaming plus motherboard

AMD Ryzen 7 5800x cpu

64gb corsair ram

Corsair rm850x psu

Ok thanks for the help I guess I will not use it.

Well the gpu was in my other pc but it went wrong so I thought it was just one of the fans had stopped working so just put new fans on it to use on this new pc till amd 6800xt are back in stock. so I guess there was more wrong than just a faulty fan.
