@trodas:

Asus P5K-E - exploded Apaq polymer cap 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 and Apaq is not exactly a good brand either. http://www.xtremesystems.org/forums/showthad.php?t=151968

OuchI bet he had to change his shorts as well as his mobo after that. :P

I remember the first time that happened to me. I was down on the ground and had my Hi-Power drawn (man I miss that pistol) before I even realized WTF had happened. :P

Heh, yea, probably yes. Who is not used to gunshots comming out of the PC, then he can get quite surprised. The accumulated hydrogen and oxygen from the water produce nice force. I seen a small, like diameter 5mm cap, exploded in PSU and it almost break thru the PCB, when it acted like a shell and get bounced from the metal casing of the PSU back at the board

So if a small capacitor produce such force, then things with bigger caps can get really nasty. From my experience, this Chemicon KZG caps: http://s10.postimage.org/j65kk9zu1/DFILPBKZGChemiconbustedbyPSU.jpg...get "opened" with strong dull sound from my PC. But still the level of noise was not so big.

However in this case - PCchips M810L v7.0a board, caps G-Luxon, mine :)

the explosion of single cap was so loud, that about half day my hearing was notably worser. And my stepbro run to the other end of the room and refused to have anything to do with THIS mainboard again.And I get lucky, because when the insides of the cap erupted from it, then not any part of my flesh get hit.

Lesson learned - powering up old mainboards with questionable caps? Better stand back...

I'm not armed (certainly not at home), so pulling out gun never crossed my mind ;D That should lead to bad mistake, lol. Dunno, if anyone who never experieced this will understand how bad it sound. It sounded to me (the G-Luxon ones) almost like a strong firework explosion, but that is probably because things sound much more noisy in home, while firewors / gunshots outside did not sound that much loud - unless the gun use some powerfull ammo, like the Russian AK rounds (6.72x39). That is really on the outside par-to-par with the loundness of the G-Luxon explosion at home. And like the G-Luxon, it some with "special effects" too - the grass near the gun get shaked badly by each shoot ;D We use our own Czech variant (quite internally different) of the AK-47 design called SA-58. Arguably it is better in some aspects (cleaning, diassembly, modifications) and not worser in others. Old good commies staged trial run between the AK-47 and the SA-58 and both are fine after firing 500 000 rounds each.Except on our SA-58 one of the springs give up, so since this time, there are strenghtened springs used. And that it is. No more loses with AK ;D It also have (because of internally different design) notably higher auto fire rate, but the slower autofire allow better aiming of original AK, because with auto your shoots are flying all over the place... so increasing the speed of kicks are not exactly beneficial IMHO in any way. You just chew thru the magazine much faster and that it is. Most bullets will miss anyway... So auto is useless, unless you want just spray bullets at area and did not really expect to hit anything.And the AK design is more simplier, easier and cheaper to made - with that we cannot compete with the SA-58.

But that is quite OT when talking about caps ;)

    • 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/
