Hi! I’m trying to fix this motherboard changing the capacitor but can’t seem to find it

it’s a smd capacitor “m7 680C UD” as seen in the picture

Hello camibritoc, welcome to the TechForum! Do you have the physical size of the capacitor? It is likely to be a 680uF 16V capacitor based on the marking code 680C. We’d need the length, width, and height.

After a second look and with support from my co-workers, the likely match is from [Nichicon’s](https://www.digikey.com/en/supplier-centers/nichicon) UUD series:

[493-2267-1-ND](https://www.digikey.com/en/products/detail/nichicon/UUD1C681MNL1GS/590008?_gl=1*d7r1tr*_gcl_au*MTgzMjU4OTcyNi4xNzgwNTgxNTAz)
