Need help identifying a capacitor on a graphics card.

It's a GTX 680,

I'm looking to replace it, but what do you think of the damage, is it okay, possibly re-bendable? Thank you for your help.

I would replace it. That's 820uF/ 2.5V if I read correctly.

Okay cool, thanks, you wouldn't happen to also have a recommendation for a site where I could purchase some of these capacitors?

The fastest way is usually to desolder it from some dead board or VGA If it's on the Vcore pretty much any 2.5-4V polymer cap with as high capacity as physically fits will be fine.

The polymer capacitors are most likely made by Lelon, since they have they the same color as those other 16v rated polymer color with the code "OCRZ" on them. OCRZ is a series of polymer capacitors made by Lelon

The capacitor with pink/magenta bar on it is Samxon ULR, should be fine. The ones with red bars on top should be Apaq based on the logo, and those are Ok as well... polymer caps are not as problematic as electrolytic caps.

You can use any through hole polymer that's rated for at least 2.5v (you can use 4v as well for example), and that's at least 820uF or higher (you could use 1000uF if that's the only one you can find cheap).

The two important things would be the lead spacing so that the capacitor will sit flush with the board and that they have very low esr.

Here's a link with suitable replacement capacitors (placed some filters to show only 2.5v/4v and 820/1000uf and very low esr), just pick the ones with your lead spacing: https://www.digikey.com/short/3wdcb7

In US, you could also check mouser.com or newark.com , both have quality components.
