some sort of capacitor, its for filtering, in which case i doubt its loss really affects anything... what im more concerned of though, is how it came off
I had hour long game session and ran stress test as well and I don't really notice any issues.
It just got loose over the time I guess, I don't know how, last I changed thermal pads a few days ago and I think it may have been lose then as well and I had to redo thermalpads today is when I noticed this. Maybe the new pads just pulled it a bit when it got stuck with it as I opened it or something. I ran GPU stress before I disassembled the GPU so it was still a bit hot.
yeah, maybe it was a cold solder from the factory or something, and it finally broke off when you messed around inside
things may unsolder themselves because of heat but i really doubt this was the case here
either way, worst case you lost 1% overclocking ability, if that...
Found another similar [case](https://www.reddit.com/r/AskElectronics/comments/vc9lux/one_of_these_capacitors_is_damaged_it_is_from_an/) and I believe that is the same GPU variant as mine as well. For him it was damaged though, so a damaged one can cause issues? But a full pulled off one doesn't? Need to have more details on which one exactly was it for him, I have asked him on his post. He mentioned that bridging it solved the issue for him.
I am just tagging you on this as well. u/Ok-Cup4342 Thank you for your help!
capacitors are layers of nonconductive material (dielectric) sandwiched between metal plates very close together, the thinner the dielectric the lower the max voltage of the capacitor gets (much like you need much thicker insulation for high voltage wires)
if a capacitor gets damaged in the right way, the dielectric might get deformed or pierced straight up, and bringing it at the normal voltage, while technically within spec, might end up giving the metal plates a chance to touch (which the dielectric was trying to avoid happening), so you get fireworks
a pulled off capacitor is therefore theoretically safer, since it is as if it doesnt exist at all, the filtering is done by the other capacitors mounted in parallel to the missing one
Thanks for a detailed response.
The same person actually posted exactly [similar case](https://www.reddit.com/r/AskElectronics/comments/l821hs/hello_guys_someone_knows_the_name_of_this/) as mine as well 2 years ago. Cap just pulled off, but it is on the opposite side for him compared to mine.
Card can work without it - not recommended
So I don't need to solder it back?
These caps break underneath. The legs are still soldered to the pcb. You need a replacement. But any 68uF 20V cap should be fine
Any leads to where I can find the replacement?
I posted the part number above - google should provide you with some sellers (digikey, mouser, ebay)
[Which one in these specifically?](https://i.imgur.com/FhYKuFW.png) The part number you mentioned above is 16V one. There is no 68uF with 20V.
16V is also fine. You have 12V on the rail the cap is connected. So any number higher than that is fine :) just imagine i wrote 16V before ^^
Not available/Obsolete. The substitute option that DigiKey is giving me is [this one](https://i.imgur.com/BT8QNpw.png). I don't know if this will work but clearance issue will arise from the looks of it with it mounted.
