What is this blown up part for a HD 7990?

Recommended Posts

Posted · Original PosterOP

Tried to power on this GPU and initially sparks came out, tried again and the fans would slightly turn then stop. What could've caused it as well? Old age? or some electric short of some sort?

I've got two 6990's that don't work, the 7 series I heard had similar problems. they just weren't reliable new. That is a blow resistor in a power stage, mosfet is prob dead as well

sparks = short, otherwise it should also give off smoke.

 

The burnt mark near the bunch of capacitors look like a short. Not sure if the powerstages are shot or just dirty.

Any possible way to recover this? Or is it complete dead? I don't know if any of the electronic repair shops around can do it but I highly doubt it.

If there's sparks it's too dead to bother fixing. 

 

That card is so old, buggy, and crossfire doesn't even work in most games today. 

 

Might as well consider it time to upgrade.
