MSI RTX2060 Super burnt capacitors

[Japie073]

I bought a MSI RTX 2060 Super Ventus GP second hand and was working perfectly but there was always audio clipping sometimes and occasional lag spikes. Which I thought was my CPU being the bottleneck but with the old trusty 1060 theres none of these issues.

Few days ago I started getting games that crash to desktop without any warning or event logs. Sometimes the whole PC would reset without warning but GPU would work fine afterward.
The weekend I got a lot of TDR resets and my display went black for few seconds. The last time the whole PC froze completely.

I took of the heatsink and noticed a few burnt SMD caps and some corrosion on the I/O plate. GPU would still work eitherway. AFAIK my PSU is okayish quality (CoolerMaster V650 Modular) as I have ran a RX Vega 56 quite decent when undervolted.

What could have caused this as PSU is 4 years old or might it be that the person I bought the GPU off might have damaged it?

Also if someone can help with the values of these marked caps it might be worthwhile to save this GPU. Photo is from google.

Thx

Nothing is burned in those locations

It's a reference photo so they can show the location of the caps, not the actual problematic board.

I doubt that's the cause, those caps are probably used for power filtering for the PCIe power connector and they're likely not critical. If there were problems with power delivery the card would probably just crash.

I'd say the card is most likely fine, something else is causing problems.

So I dissassembled the card again, and yes the previous picture was for reference only.

Near RS2 there is 3 ceramic caps that burned out and also near L21 theres 2 burned caps. Could it be that moisture had built up on the board as there is corrosion on the I/O plate and some of the screws?

Okay yeah, THOSE are burned

You can see physical damage to the lower one, could be faulty parts, could be moisture or any conductive debris - or even a bad PSU sending too high voltages that they couldnt handle, that somehow the rest of the card can


Being so close to the power they'd be related to it in some way, with them damaged the card may have voltages that go out of spec and cause damage later, or they may be for a specific piece of hardware - as a random example maybe they run the power to the HDMI audio, and only that no longer works

Replacing those is easy to do but I'd be worried about WHAT made them burn in the first place - Could be a symptom of a deeper issue within the card.

If you have the correct soldering equip it's a snap to do other than just having to do it but many don't - Luckily I do and can do that kind of work.
Only real way to know what's up with it is to get it fixed/fix it and see if it happens again.

And believe it or not, (From my personal experience) as long as the caps you get are the same size and exact shade/color (Using the first pic you posted as reference) they will work and can be literally robbed from sources such as a dead motherboard you may have lying around somewhere.
Size them and match the color is how I've always done it.
I've done many of these over time and never had a problem over it (yet).

I desoldered those and tested the card again, seems to work fine but no longer trust it and don't want to risk damaging the rest of the system. I suspect there is corrosion causing a short circuit. Putting this card to bed now.
