I broke off a GPU capacitor, what should I do?

[BigSaki]

While cleaning my gpu I knocked off multiple capacitors near the gpu die. All the pads are intact and I even have on of the capacitors in a bag. How can I find out what capacitor it was? The gpu is a 1080 ti ftw3 from evga.

Honestly chances are the GPU will run fine. It would only be an issue if you are like perpetually maxing out the gpu while undervolting it (like in mining). But for gaming use the gpu should be perfectly fine. Nvidia would most likely have over-specced the amount of bypassing on the rails so if a few tiny caps fall off it shouldnt be an issue.

may pull a pin to meter it, if it's faulty try to meter its place V, and oscilloscope/else way to get freq.

hopefully could figure out whether its function either as
- storage
- bypass  (to filtering or coupling) being || of s.o. intended to solve, which's more often likely

You can look at the size of the caps. Then look on the board for simlilar sized. Read the values. Those are polymer smd caps. Just get some from digikey or mouser. Unless they're through hole, but those don't usually fall off. Then, you'll need some bluetak and a heat gun. Affix the caps to the board  with a tiny piece of bluetak. Use the heat gun to solder, unless you''re good enough to use an iron. You also might want to heat up the others, to make sure they make sure thaey're soldered down good.

There's also an over controller you can get that is 120V. You can use a toaster over, and program the controller the way you need to resolder everything on the board. It's a great thing to have for computer stuff, which is forever getting cold solder joints.
