Bunch of Nichicon HM's from old HP D510S/845G. To my suprise, powersupply was full of HZ and alike, all good.

Is that computer an SFF style machine?

If so, not surprised. Those computers are a true test for capacitor thermal ratings.

Don't buy Seagate drives. Don't use Seagate drives. If you have any in service right now, make plans to replace them ASAP.

Looks like H0301 on the datecode. No surprise since it's in the middle of the bad era for the Nichicon HN/HM series.

Some caps from a grab bag; a (brand new) Samxon GF 47uf 25v that is blown out the bottom. A Rubycon MFZ 680uf 4v cap that is bulging (tests at 230uf). and a Samxon cap with a heat shrink error (nothing electrically wrong with it).

The Ruby MFZ probably sat on the shelf too long without use, and they don't like that too much either (though nowhere near as sensitive as UCC KZG). I've also never seen MFZ in that size offering (680 uF @ 4V). Custom spec caps, I suppose?

As for the Samxon GF... meh, those are known garbage. Not surprised it failed.

The blue Samxon looks like GS series. Those are general purpose series... and also not very good, especially if there is any heat involved. Also, that sleeving error is very funny. I've seen caps over-sleeved or under-sleeved - even from the good Japanese brands, but nothing this bad, lol.

yea me three! i find sleeving errors very funny too. since this isnt the vip room, all i can say is that under-sleeving reminds me of women wearing shirts that are too short , exposing their abdomen or someone walking around in public in various states of undress.

over-sleeving reminds of someone wearing a fat suit or wearing clothes that are too big or too baggy for them. in short, over-sleeving and under-sleeving make very poor fashion choices for a fashionable capacitor or if u want to have a capacitor that looks fashionable, aesthetics wise.

Ah, that explains the g-rated analogies above, then.

Otherwise, I was expecting the jokes to be more about extra skin (or lack of) on certain... oh yeah, this isn't VIP/off-topic. NVM!

Talking Re: The Hall of Shame - Badcaps Photo Montage

Cap bulged after sitting unused for a couple of months...

This is a constant-current load I got off Ali in kit form. I soldered it together myself and it works, but it just sat in a box on a shelf for a good 6 months now while I was planning to build a case for it, which I never really made much progress on I came across it the other day while I was looking for something else in the same box and noticed this, which struck me as odd. However, I think I remember someone saying something around here not that long ago about caps going out just by idling for long periods of time, so this could be it. Not sure if the position of the can itself plays a role in this - this board sat on its side, for the record. It wasn't exactly cool where it lived for the past months, but certainly not boiling hot or in direct sunlight either.....

Yup.
Caps with unstable electrolyte tend to do that, especially shit caps from China.

Good Japanese caps can sit for a few years on the shelf without use and have no problems afterwards. Of course, if stored for more than "a few" years, their specs will slowly start to deteriorate (generally, they may need reforming to avoid high leakage current and possibly shorting out from that.) Nonetheless, I haven't had even 10+ year old new Japanese caps go bad on me in storage - at least not series that are known to be solid with minimal or no failures. Chemicon KY, Nichicon HE, and Panasonic FM are a few examples.
