SMD explosion on HD 5870, need replacement

Watermelon5 · Sep 2, 2022

Noticed fan was not spinning on my HD 5870 so I disassembled it and found this. It's an engineering sample (which is why I am so concerned about fixing) but I believe this area is identical to the reference model.
The issue is very obvious. capacitor... B200? Hard to see through the burn marks.
I believe this all started when I put a fishy PCI card in my PC, powered it up to test. Heard a pop, thought it was from the PCI card but now I know the source... I am experienced with soldering so I should be able to fix, I just need to know what this was. Is this capacitor something I'd be able to just remove entirely and bridge the pads with solder? Should I try to find what value it was?Maybe it's the same as C209, should I test that one and buy another of that? (or am I totally wrong and this is a resistor... but I think only a capacitor would explode this violently)

In the TPU database pic, it looks a little more like the C202 SMD - bigger than the C209.

Don't bridge the solderpads , you will create a short and damage the card even more.

Clean the surfaces darkened by explosion with isopropyl alcohol and then read what that spot is supposed to seat B=bridge, R=res., C=condenser. Then pull the appropriate one off an old non working component (mainboard) or buy it and replace it.
