So I have an Intel D865GBL board which I found in... quite poor environmental conditions (I posted it a few months ago in the Found Hardware thread... it was in bad condition). Anyway, I finally got around to cleaning it up and it's in pretty good condition now... except I found one bulged cap... just one, it seems to be near the BIOS (not sure if that's relevant). See attached photo.

So, question is, should I go to the effort to replace it? The board works fine otherwise...

I have 3 of those boards. Sturdy, high quality things, only missing overclocking options 😉

Are you able to solder it yourself? If so, I'd just replace it, it would be a shame if you forget about it and after some time the cap starts leaking through it's legs and corrode anything around it.

I would replace at least the bulging cap, if not the rest.

Just because the others aren't bulging doesn't mean they're OK. They would presumably be the same brand/specs and would have been in the same nasty environment. The remaining onces will probably bulge/cause more problems in the future.

Also, on closer inspection they're all Nichicon, except for that Rubycon one just behind the RAM slot. Maybe the previous owner replaced a single bulging cap?

It could be made in a dfferent month or even year but mine has a Rubycon MHZ there, the same type as the black/gold cap close to the chipset heatsink. The value is the same, though - 2200uF / 10V.

2 of my boards have a Rubycon MHZ, one has a black Nichicon, the same kind as in OP's post so it's original, just different mfg. date.

Based on it's size, I suspect that's a low ESR cap for filtering a buck converter. Definitely replace it. If you can check the cap for the series code, it might be an HM or HN cap which were known to be problematic for Nichicon around this time.

Ya, for sure, I'm just lazy 😊

Guess I'm replacing it 😀
I think I probably have a 2200uF 25V or something lying around. I'll see if it's appropriate (that said come to think of it might be as old as the board itself anyway...)

Just out of curiosity, what series was the blown cap? You'll want to do a spec lookup when sourcing a replacement.

Well, I replaced it (2200uF, 25V instead of the original 10V)... we'll see how long this lasts now (both the new cap and the other original caps). It's been good for a whole hour now. 🤣

Hmm... Vishay are decent caps, but they don't have a good low ESR line. Hopefully that's not a cap for a VRM.

Got a picture of the original?
