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

Yes, card is shorted .
Do not, plug it again.
I tell u Do not plug It again.

Your power Supply have build in short protection And its earning its money by preventing fire and smoke.

U have to take your card for repair.
 
I have the same card, plugged it in the other day. For a card so old it is surprisingly power hungry, needs both an 8pin and 6pin power connector, if you are using 6+2 for the 8pin make sure it's fully in properly as sometimes the 2pin isn't fully in.
Try using different cables from the PSU, preferably dedicated ones rather than running via adapters.

Each time you plug it in and the SCP (short circuit protection) of the PSU kicks in that power was sent to the wrong part of the card. Don't do it too often - only bad things can happen. Not wanting to worry you but worst case is you send 12V to the wrong PCIE output and damage the motherboard. If you really must switch it on then put the power to the GPU but have the GPU itself not seated in the motherboard.

It is obvious by the description , if main gpu power rail shorted , chances are u zapping main dye with 12v every time u power It on.

Dont power it on, if u have any hope of trying to fix it.

Instead take off the cooler and investigate if there us any burn Mark's and if it's Smell burned.

If no smell is detected Then u have reasonable chances of a repair .
It all depends if 12v ever got to main chip.

Btw I repair Gpus for hobby, so I can give u some basic advice.
 
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.
