Horrible pictures of dead caps


Recommended Posts

I would like to dedicate this thread to the most horrible pictures of dead caps you guys can find ;) :D 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 ;)

Oh, you think that this never could ever happen to you and that copanies are "learned the lesson" of China made (and fake) caps and now things are different? Well... not true. They are just hidding the bad caps better now and that it is. Want recent example? Sure, there you go:

Sapphire Radeon HD 7870:http://www.techpowerup.com/174858/some-sapphire-radeon-hd-7870-cards-affected-by-black-screen-issue.html

The cause for GPU electrical signal noise is found to be bad quality ceramic capacitors responsible for conditioning power to the GPU.

So bad ceramic caps (yes, these little brown someting with two electrodes as it's ends) could happen too, as you can read from respectable source. I never seen (yet) bad ceramic cap, but looks like that everything could happen and perhaps the designer just did not understand the serious voltage bias of most ceramic caps? See: http://s9.postimg.org/3yqikalcv/TayoYudenDCBiasGraph.pngDunno. But it clearly show the problem, when the company try skip too much on caps. Bad things can happen and plenty of angry customers that are playing games and then got black screen with sound loop and have to reboot aren't exactly happy.

So even that this thread show pretty outdated hardware (mostly), then it should be never let out of the sight, what we got once sold for a crap caps. Todays there are even custom made Nichicon FP caps with 5 000 hours lifetime (FP 5K) on many Asus mainboards, so if these are geniune, then these boards should last lifetime under regular cooling ;) (with each 10C down from 105C is the lifetime doubling, so 2 000h caps are at 55C guaranted to run 14.7 years nonstop, these 5k ones should be good for 18.7 years at least)

So bottom line - cooling if necessary and airflow in case is not a option, but the requirment.

Sapphire "Grouper" PI-A9RX480 boards are dying because Sapphire used Teapo caps, the the boards died during reviews:

http://www.xbitlabs.com/articles/mainboarde-x200p_14.html"During our stability test of the overclocked system ...suddenly shut down. The verdict was: mainboard death. ...mainboard died because of the failed capacitor in the CPU voltage regulator unit. nothing could help our poor CPU at that point."

http://reviews.pcapex.com/motherboards/sapoard.php?page=4"me share one more experience that I had with this board... It died. I can only hope that the death of my board was a fluke." Ne, nebyla to "fluke", byly to Teapo kondky Pozd?ji text zm?nili na: "Our investigation revealed that the mainboard died because of the failed capacitor in the CPU voltage regulator unit. We sent the mainboard back to Sapphire for further examination, but nothing could help our poor CPU at that point. It rested in piece, too."

So because of bad cap even a CPU died. You have been warned...

Now what about PSU on fire thanks to Hec caps? Klara's PC (Morphys friend, girl - but not girlfriend :) ), Eurocase PSU - Hec caps:

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

But let's get back to the Eath for now. Back in spring 2011 these dodgy capacitors were responsible for the signal failure at Sydenham (Australia) that brought the cityrail network to it's knees:so it is not just computer geeks (overclockers and silent PC lowers in perticular for the overstress and lack of the airflow) that are affected by these "designed to fail" caps. It does affect everyone.

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 Nichicon HZ on my own mobo:

Find a difference between logo of Fuhjyyu and Hitachi:

Hitachi or Fuhjyyu

Where Fuhjyyu is known crappy bad cap brand, while Hitachi made a good caps. Therefore if we cannot just flat out fake it, then we make it at least very, very hard to distinguish between good and bad caps.

Lelon - known brand of bad caps in action. Caps for pictures provided by -HoNY-, same caps are used in cablemodem, witch I leasing to be used by my ISP provider. They will be surprised what I do to their Lelon caps Especially when under heavy repeated load the modem stop accepting new request for same server, so... these caps are - even years after it is known they are crap - widely used in electronics, causing all sorts of problems. Any look at them - who can even wonder?

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

(yes, server boards are not imune to bad caps too, this was the legendary batch of Nichicon HN/HM caps, that Nichicon screwed up and they are all died sh*t happens even to Nichicon...)

Sacon FZ caps on Magic-pro - it is a JetWay OEM

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? Now we know, that GSC = Evercon = Sacon = Apsun - and this is not good news at all:http://www.badcaps.net/forum/showthread.php?t=3369http://www.badcaps.net/forum/showthread.php?t=4341

My DFI LP B mainboard lived nicely and peacefully, till a loud explosion come out of the case and machine fail miserably. When I check it out, I see there a Chemicon KZG caps in the Vcore input filters (1500uF 16V ones) entierly destroyed:

And machine no longer working. That way exactly the wake up call for me, regarding bad caps :( Yea, Chemicon's are supposed to be a good caps (except the KZG, KZJ, TMV, TMZ ones), but even good cap can fail when before him is a BAD CAP in PSU that generate excessive ripple And in the Antec NEO 480W PSU are Fuhjyyu caps, witch are considered inferior crap even between bad 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!

    • Hello everyone, now I am choosing between several laptops, but maybe you can advise me something better my priorities: mostly just for home, for watching movies and YouTube, for some light games (a couple of times a month), and sometimes for work (mostly google drive, various marketing resources, nothing heavy) around 600 USD 15.6" or more Acer, Asus? Order on Amazon? Windows prefarable 256 SSD or more. I will leave links of those notebooks that I am thinking about now https://www.amazon.com/Acer-A515-44-R41B-Hexa-Core-Processor-Graphics/dp/B087N4ZRXV?ref_=Oct_s9_apbd_simh_hd_bw_b2N0e&pf_rd_r=61THRATEMWAKYQZB6J7M&pf_rd_p=121acd9e-769b-5530-ae68-5a92ebd704d6&pf_rd_s=merchandised-search-10&pf_rd_t=BROWSE&pf_rd_i=565108 https://www.amazon.com/Acer-A515-55-56VK-i5-1035G1-Fingerprint-Keyboard/dp/B087RTV311/ref=sr_1_10?dchild=1&qid=1613042065&rnid=13896617011&s=computers-intl-ship&sr=1-10 THANKS!   Cali employee monitoring software
    • Hopefully, everyone can get this card before the bots do. Full unboxing of the new Nvidia 3060 Ti Gaming X Trio from MSI below:  
    • Rest assured that no matter if you choose a mainstream Core i5, a high-end Core i7, or the enthusiast Core i9 that you will be getting a very good to excellent processor. All three offer a lot of performance without all that much upfront cost. It just is those who want to get the best, most optimal, option for their needs should put more time, thought, and effort into their decision. So do your homework. Think about what you actually do with your system. Then come to your own conclusions. Not what anyone, including us, tell you what you should be buying. Doing otherwise may result in a rather major disservice to yourself and your next system.   Read the full review below: https://www.realhardwarereviews.com/intel-core-i7-10700k-core-i5-10600k-review/
    • In summary, if you are looking for a good deal, do not need it to be ‘the fastest’ PCIe 3.0 drive going, and do not plan on hammering it with more than 50% of the free capacity at one time, the Silicon Power UD70 2TB is a good option at a great price. Just understand the target demographics it was built for and the compromises required to hit its low asking price before you track one down.   Read the full review below:  https://www.realhardwarereviews.com/silicon-power-ud70-2tb-review/
