PROBLEMA Zotac Rtx 3090 Trinity graphics card with three blown capacitors

[wleying68]

Good morning everyone
I have a Zotac RTX 3090 Trinity graphics card with three blown capacitors, they are: D10836, D10837, D546. Anyone have any idea what kind of capacitors, better yet where they can be found? Thanks!

Credo che non basti solo sostituirli, potrebbe aver un problema che si potrebbe ripresentare.
La scheda non é in garanzia?

Remove those diodes and check for shorts. If there aren't you can think to try to replace them.

Good evening, thank you for having answered me promptly! I found the short, so I think just replacing the pieces should make it work! in GPU-Z i saw that the core works. the problem is to find the right parts, to know the exact data of these capacitors.

Grazie per mi ha risposto, non è piu in garanzia, perche la problema nasce prioprio quando monta il waterblock con backplate curvato (danneggiato nella spedizione) che tocca i punti della saldatura. Spero ho buona speranza di salvarla, visto in GPU-Z il core funziona ancora.

Was the board reverse powered? I think all 3 diodes are meant to protect the board from reverse polarity.
Check if they're between +12 and GND. So theoretically you can use the board without them, just double check your connections!

The problem arises precisely when he mounts the waterblock with the curved backplate (damaged in shipping) that touches the welding points. It can't work, I got the GPU-Z data using internal video.
I asked for Zotac assistance, but they replied like this:

Sorry this is our internal product design data and it cannot be published.


Now I don't know where to beat my head.

I would search for the same as D10835 (just under connector J1)

Thanks, I ask my technician if you can take measurements with D10835.
