Question Missing capacitor on MSI RX580 8G ARMOR

[lifesgood1337]

I bought a broken rx580 with the hopes of repairing it and learning how to do so on the way, but I've come across a broken capacitor which I don't know what to replace with. Could you guys help me please?

(newbie on the forum, so, sorry for no tags and stuff
Also I don't know how to add images)

found the exact same capacitor and solder it

I mean I kinda know that I need a 16V rated capacitor I just don't know how many farads I need.

Makes you wonder how many cold solder joints per board were produced. Stay away vid card for me.

Is it that bad?

 

[rgd1101]

buy another broken exact same model of the rx580.
and hopfully make 1 work

When the board was run over the wave solder unit, the results were less then acceptable. Very bad problem.

For example this one?

These are on the backside near the core mosfets, for the 12V.
SMD Ceramic capacitor.

That's my last resort

Oh crap

I guess which ones are you talking about specifically. I see some through hole capacitors, but around the power delivery are surface mount ones.

16V 270mF is pretty common. In an ideal world you could track down the actual capacitor specs, but I am having trouble tracking down that brand.

So I would at the minimum try to match the physical specs, get the diameter and height, match the voltage and rating, and the ESR and other variables are likely to be close enough for operation.

The line of 12V input, surface mount ceramic capacitors next to the 8 pin connector. To be exact the one on the top is what's missing for me

Maybe this could help...

Thank you, but I cannot find that particular section of the card sadly. It's a 2R2 and a 0R among some ceramic capacitors on the back in line with U508 on the other side.

Let me know the number of missing capacitor, for example C503 and two or three capacitors or resistors nearby.
