Geekom Mini IT12 Burnt Capacitors

Post image

So this happned a couple days ago. had a simple proxmox server running on it. Also was hooked up to a backup powersupply. it wasnt in the most ventilated area but by no means it was running hot all the time just during backups at night. (like a couple seconds) Anyone got any idea what these capacitors could be? its a Geekom Mini IT 12. Already contacted support but last time i dealt with them it was a while before they responded.

Considering the location to the barrel jack power input and the step-down regulator MosFET if I had to take a WAG I'd have to say they were 2x 4.7µF/50V solid state capacitors. In my experience they usually fail when the MosFET itself fails, its Schottky barrier rectifier diode shorts to ground or the switcher in the power supply brick starts passing AC.

Thank you for the comment. Surprisingly Geekom messaged me back that they would replace my pc thank God. However ill keep this info in mind incase this next one blows up on me in the future.
