I would like to dedicate this thread to the most horrible pictures of dead caps you guys can find Just to scare these guys, who think that "this can never happen to them" Let's start with HP Pavilion machine pic. TMS 1500uF caps, machine shutting down in 30 sec after power on:



Frankly I would not dare to turn it on... Picture from Carcenomy user on TechPowerUp forums

Klara's PC (Morphs frield, girl - but nto girlfriend ), Eurocase PSU - Hec caps:

CapXon caps rulez



Bulging sligtly and leaking Vent cap, and some nonstandard inferior Fuhjyyu caps - 1650uF 16V? OMG!
Much to my surprise, the CapXon . caps are used in Fortron PSUs:

I just photographed JetWay V400DB caps. I think everyone will like the sight



6 pieces of GSC 2200uF 6.3V

lol, it is like a full on fire

haha, sweet! God, where the hell does tazwegion hide when all this retro stuff is coming into OCC since Trodas joined?

nice finds, I hope to add my pics here soon

Holy crap, that is really scary.

Thats a lot of wasted blue smoke. Think of those overworked wizards.

Let's have another shall we?

However mine's still able to fold 24/7

the man has a filthy obsession with caps!

trodas... how did you develop your cap fetish?

Its not a bad thing, I'm just curious (I'm going to school next year to be a computer engineer so I'll be doing similar stuff).

Can these be cleaned? How do they get all filthy?

No. They get dirty because they are leaking, IE: bad.

Worst (and only) that I have had is the MSI MS-6368 v2.1. All of the ones around the CPU socket were slightly domed. It would keep locking up unless I kept the CPU loaded at 100% (sounds a bit backwards eh). It has been fine since.

Silverfox - I would preffer not to have - I have other fetishes, far more exciting and pretty that caps... And especially busted ones, lol


Propane - my caps fetish? First at all, I did not have any caps fetish, lol. Second, well, it was one peacefull night where I was reading some stuff and then a loud explosion in my computer come and like 5 sec after the display went FUBAR and till I exchanged the mobo caps, it never posted again...
Later I learned that these Vcore imput caps, Chemi-con's KZG that give up are reasonably good caps, but the Fuhjyyu ones found in my Antec NEO 480W PSU are the ones that killed these caps on my DFI LP B mobo.

That and other problems and failures that happend to me make me care about caps a lot. So I just sharing my knowledge now


coolcat97 - yes, they can be cleaned. No, in long run it did not help at all. They are leaking the the mobo are dying because of that. If you wait, they call kill everything, including the mobo mosfets and Vcore regulator. Have fun repair THAT!


markiemrboo - congratulations on nice recap to Rubycons! What are the orginal caps anyway? The green one is probably G-Luxon, right? But the Vcore ones...? Also G-Luxons, or...?



OST cap from SETI forum - I quess the extraterrestrials got him

Gigabyte GA-8IRXP mobo, user smargs2 from OCAU forum and 3300uF 6.3V GSC caps



(he recapped with Nichicons and mobo is now working well )

My memory is quite bad at the best of times, but I do believe the originals were Chhsi.

markiemrboo -

Heheh, thanks. I do believe you got them right...


Even Apple sometimes use bad caps - but these looks as Nichicons HN, witch are quality ones (except for one bad batch). The catch? HN(M) stays for Nichicon, yes, but these are black-white, not black-gold. Only gold ones in Nichicon line are HZ ones... Hence they are fakes and Apple bought fake caps and then selling hatdware with them to their customers... that will fail. Amazing.



True Nichicon HM with Nichiconem HZ on my own mobo:

I do not have any pics, but I've had a "500 watt" ghetto psu burst a cap sending a horrible smell through my room, burnt the solder and the area around a VDIMM mosfet on my 9nda3+(Probably the RAMs fault, hynix-B chips didnt take kindly to 3.2v for too long...), and got a leaky cap near the socket on my old scktA ECS mobo'd rig.

What a horrible board that ECS one was!

It's damn shame you can't share it with us, but what we can do...


Now... what about a picture of busted GOOD cap Chemi-con KZG in DFI LP B Vcore regulator inputs? Cause of death? Fuhjyyu caps in PSU! (Antec NEO 480W PSU) Fuhjyyu ones usualy does not bulge, so you have no idea that things are going wrong... if you don't know that Fuhjyyu caps are inferior crap even between bad caps!
You live nicely and peacefully, till a loud explosion come out of your mobo and your machine fail miserably. Then you check it out and see good Chemi-con KZG caps in the Vcore imput filters (1500uF 16V ones) entierly destroyed:



And your machine no longer working. That way exactly the wake up call for me, regarding bad caps Yea, Chemi-cons are supposed to be a good caps, but even good cap can fail when before him is a BAD CAP that generate excessive ripple...

Time for some hardcore GSC failures!

GSC caps - Peter's GSC caps in GF2MX400



...and even the topmost left one, witch looked "reasonably" well for GSC look this way from bottom:

lol when i saw this thread's title on the front page, i thought it said "horrible pictures of dead cops" and i was scared to read the thread. fortunately - i haven't had the chance to take pictures of dead caps

Dead cops? OMG! What the hell you did wrong that the first time you see "cop" instead of "cap"? Confess, or you will be taken on Guantanamo where you will confess of all sins you never ever knew you commited


Lelon - known bad cap brand - busted:




Lelon caps provided by -HoNy-

Picture I saw the other day:

That's brilliant

Yea, I saw that and was like "Those sneaky little bastards..."

That's SO mean though You're thinking sweet, awesome (insert good brand name here) caps, not the crappy Fuhyjiju (?!?!) things, and then it turns out to be just that

Yea, I saw that too and it is fantastic It is not shopped anyway... so sad.



Well, the catch is, that you think you have a 6800uF 50V cap and all you have is a 2200uF 35V cap. What if you use it at 40, 45V? Even Ruby give up if you overvolt it!


Dell Precision 450 with Nichicon caps, user markp, OC AU forums.

That's definitely a cool array of RAM slots there Trodas

That is mainly a SEVER board using QUALITY Nichicons busted up
The truth in this very sad story is, that they used the one big batch of Nichicons that are known to fail - a manufacturing error. It simply happens. But the results could be disasterous.


OST cap in Asus P5AD2 Premium, used approx half year with P4 3.6 GHz (Prescott rev D0 (119A current...) )

I actually very recently (two weeks ago) accidentally used 16v Panasonic capacitors in a basic linear power supply, for a preamp, with a 15VAC transformer, giving ~22VDC rectified. This was on for a week and a half 24/7 before, for some reason, I suddenly realised my mistake. I wasn't even fiddling with the thing at the time. It just popped in to my head for no reason.

I opened it up expecting something horrific, but all was actually perfectly fine - cosmetically at least. I replaced them with 35v Panasonics, naturally...

I've read reports of someone using 200 odd volt caps(?) Nichicon... UCC... can't remember, where 350 odd volt caps were needed(?) for a week without any exploding / leaking or what not I found it quite err interesting [slash] impressive.

Yes, wow, this is indeed impressive. When I downrate voltage (because I'm always short on "special" caps, like 470uF 25V Panny FM or 47uF 50V Panny... eh) I always check before with a scope for the highest ripple. In a Enermax 485W PSU, these above mentioned has the highest ripple of 13 and 14.4V respectively.
Lucky.
I did no suggest that to anyone, tough.
But yes. Good caps has some headroom (not very much, but do have) and Panny being especially well-dimensed in this regard.

However if you polarize them wrong - well - that is what happen to Panny FM cap wrongly polarized by my mistake into Abi ST6R mobo as imput cap for Vcore:

User Random Murderer from TechPowerUp swear that this is not result of lighting, but "just" a bad cap that exploded...!

Asus P5K-E - exploded Fujitsu polymer 270uF 16V on Vcore imput, just right after PSU...



Why? Well, because user NewBeetle from Xtremesystems forums did overclock with OCZ PSU and only a 520W one, and filled with Teapo caps...

User Grings from TechPowerUp forum.

man that would suck to have a cape explode while the computer was running I would be super pissed. lol also some pretty nasty picks

Well, it happen to me and countless others as well. And yes, words hardly describe how much we are pissed once we learned the truth about WHY that happend...

Sometimes things get much faster:

Don't let them fool you. They are NOT polymers, these are sleevless electrolyte caps, and a bad ones, I might add. JetWay do this all the time. Remember their mobos full of GSC crap-caps?

X-Fi Fatal1ty soundcard, 220uF 16V Jamicon crap cap, user Raggingbone from Creative forum.



PS. bad caps, Jamicons, are on X-Fi used for voltage filering (even they are not low-ESR at all) as well, as for audio signal decoupling (even they are not audio grade caps at all and hence they damage the sound of the card notably (!) ...). Thanks, Creative!

I though solid cap's where supposed to be ultra durable....or was this person overclocking/voltmodding etc?

Ultra... what? I'm sorry, but do not trust marketing. Look up in the makers specs. They in datasheets mention a little thing called "Endurance" and the BEST polymer caps has 2 000 hours. Check it out, the best of the best polymers, Nichicon LE: http://www.nichicon.co.jp/english/products/pdf/e-le.pdf

Worser, cheated and fake polymers can last only 2 hours, of course.

The load life is mentioned for rated temperature (usually 105°C) and maximum ripple (if the maker of mainboard/GFX card did not took off much caps from the mobo/card, it should be run well bellow maximum ripple to enhance the endurance).

For each 10°C down from the temperature, the cap lifetime double. Some claim not 2x like for elytes, but 4x for polymers, but I have yet to find datasheed that confirm this. Marketing department of Gigabyte is not trustworthy source. For more info, loop up there: http://capsmod.net/forum/viewthread.php?ti...;extra=page%3D1


Now what you saw on picture was not a polymer cap at all. While it is true, that earlier polymers has the top perforation like elytes ( http://img396.imageshack.us/my.php?image=msi63404ez7.jpg - http://img147.imageshack.us/my.php?image=msi63405qe1.jpg ) to prevent strong explosion in case of overloading, modern ones stop having it. Probably marketing reasons (polymers never fail, you know...) and it is also cheaper.

What you saw on pic is electrolyte cap, just made to look like a polymer.
They got ya!

Polymers are not "miracle caps", their usage is very limited and they do not belong in many places where you can find them todays frequently. I can explain that in great detail, but I dubt anyone will ever listen. Just check out Intel boards, they know that polymers are good ONLY for Vcore output and that it is. No markething BS change that. Get used to look at this:


Asus P5K Vcore input 270uF 16V Fujitsu polymer exploded after mild overclock Q6600 to 3GHz with 1.30Vcore...

man some of them pics are awful. This thread should be censored

Heheh, you censor!
While I definitively do agree that many of them is so awfull that it hurts, well, I cannot agree on not showing them. You know - people must know for sure that this is how the companies (all of them!) cheating them. And that it is not some "isolated issue" or "only your problem" or some other BS the RMA department always throw up at you, if you don't know...
