Repairing an RX 480

Hey folks.

I have an Sapphire RX 480 Nitro+ 4GB.

It went kaput in a very abrupt way - PC shut down right away.

Upon testing it, i found out, that the 2 fuses at the 12V PCI-E connectors have blown, and there is an element that is shorting.

I went to a repair shop to have it repaired... but they told me after 2 weeks, that they cant find actually replacement parts for the fried ones.

So, any good suggestions on what i may try?

PCB pic might help. Might want to search for another dead gpu to cannabalise for parts. Whatever you do should be cheap.... you can replace the whole card for around $80.

Yea, thats why i am looking for some ideas. I was planning on selling it for ~80E, then it died.

Was hoping they could fix it, expected repair price was about ~30E (still on profit), but... with no parts sounds like it could end up as a scrap.

Anyway, i have encircled the damaged elements. The first (top one) is the 2 fuses.

Then its the element, that i believe is shorted out (always has contact), and i think it is supposed to be a VRM module for the frequency or something like that.
