C377 Blown Up GTX 690

[Dororo00]

Hello everyone
Yesterday I saw the component C377 of my GTX 690 blow up, to be honest, I have no idea what caused it but I suspect on the motherboard, since it started doing some weird stuff to other components but nothing destructive, another system I have POSTs with the gpu installed and the corea still get warm as well as the vrm but it seems as I can't get video output. I witnessed the component getting blown up, so I know for a fact it's that one, so I'd like to know some things:

1.- If there is a posibility that the GPU is still fine itself and just got a single component blown up or am I screwed (I found no schematics for this gpu after searching).
2..- The specs of the component I'd have to search for to replace that one.
3.- Could it be a failure by age? It's a capacitor afterall, I think, but I don't know that much to be certain at what caused the component to blow up.

Any help is appreciated and welcome, thank you all

Can you post an image of the unit ? ..At least the area where C377 is ?

Sure, I have one already taken, is close to the PCI connector, if you need more photos I'll make them

Okay . This smd capacitor is 0.1 microFarads ,50 volts (equivalent to ceramic 104) , similar to nearby C381 and C383 . Just In case you need to be more assured , measure C381 and C383 .

Thanks a lot, will meassure and look for the capacitor tomorrow, have any idea of what could have caused it to blow up by any chance? Cause if it's motherboard related I'll just throw away the board, if not, the PSU used was a brand new MSI MAG A550BN (was a server so the gpu is on idle constantely) to start the return, thanks again

Re: C377 Blown Up GTX 690

Welcome friend .. My best guess , it was blown while installing .. Some areas in the mobos would keep a standby voltage even when the comp. is off but wired ..In your case , it's definitely a surge from outside the VGA .

I see, thanks, case is it was working fine until I powered it up in the morning yesterday, friend told me it wasn't showing as online, so when I arrived it turned off itself and wasnt turning on, so I reseated the psu cables without touching the gpu, put the psu on the 1 position and when I pressed the case's power button it turned on but the component in question blown up, after that the PCI-E slot of the motherboard doesn't work anymore so that's why I guessed it's a mobo issue sinve it showed weird behaviour before (the m.2 slot was acting weird and made an already failing m.2 stop working and one of the ram slots broke itself) but as said I don't really know that much

Yes , your analyzing is definitely good according to your explanation ..Since we're now sure the problem came from outside the VGA , anyway , then it's better to avoid the suspected slot ..

Well out of curiosity I connected it to another PC I have, since my main one has Windows 11 and legacy GPUs aren't supported and... It just works 2/2 GPUs detected video signal is ok drivers installed, all good, no problems for now, my questions now are:
Should I replace anyway the capacitor? And Was it acting as a "security" meassure?
Thanks again

Definitely .. but I suggest you put another one for the same reason .. Even if you put a ceramic capacitor labeled 104 (0,1mF), it would be fine .

I see, at least it is okay

Is this one I'm searching for? It says 104 but I can't seem to find the smd version of it

I gave that choice , in case you have any old not used boards , from any devices , such a radio, an amplifier or so , and in case you don't want to order online , that's all . The 104 is exact .

If you want to order the smd type :
