unknown solid cap
Hi, does anyone know what brand they are? They seem very generic, I did not find anything about it.
If someone could help me I would appreciate it....

Re: The Hall of Shame - Badcaps Photo Montage
Last Sunday 2 Nichicon (I don't know the series, it has a strange numbering) passed away after 58,000 hours of service, I turned off the monitor of my server to make some changes, and it never turned on again, I replaced it with 2 nichicon of a old broken MSI board, and it's back to life.
I hope I can finish my CCFL tube lifespan experiment, it's still bright enough for the hours it's been working....Leave a comment:

Re: socket 775 forever... no, no, no...
I gave my friend my trusty old Gigabyte ep45-ds3, it's 14 years old, it hasn't failed at all yet.
I've seen more socket 478, 462 boards fail than socket 775.
But 775 had many different chipsets, the ones I've seen fail the least are from Intel, the only dead intel chipset I've seen from Intel was a G31.
Although the G31 had 60,000h of use.
The most reliable boards for me are the socket 775 ones that use os-con capacitors all over the PCB, those boards never die. (For example the Gigabyte EP45-DS3 uses os-con capaci...Leave a comment:

Re: Hard drive reliability
The 9/10 series came out very well, and I'm sure it can do at least 50,000 POH more hours.
Another series that is doing well is the 1BD142, they are very reliable too.
Mine goes for 77.991h POH.
Although I don't know if the CPU will be able to withstand so much use due to the degradation of the silicon....Leave a comment:

Re: best cheap/free scores 1.1
Yes, it would be a good idea.
5 days ago in the same place where I found the Lenovo, I didn't realize that there was another Lenovo with an i5 8400 with a 256GB Intel NVME SSD, but I will teardown, and I bought an Asus B365-A on Ebay (as soon as it arrives , I will put 2 8GB DDR4 memories), I will put a GT1030, and in the future I will put an RTX 3050 when prices go down.
And I will have a good machine to emulate wii, GC, PS2, etc... (My intention is to make this PC silent for HTPC connected to my 4K TV, so I can watch movies in...Last edited by kevin!; 02-20-2022, 07:43 PM.Leave a comment:

Re: best cheap/free scores 1.1
I recently found this lenovo V530-24ICB AIO with i5 9400t at the electronic recycling center , they threw it away because they broke the screen.
I soldered a 20v 6A PSU and connected a screen via HDMI (it has an HDMI output), and so far it has not given any problem.
I was amazed, it had 8GB of ram, which I later expanded to 16GB of ram, and included a 256GB Samsung SSD with less than 6000h....Last edited by kevin!; 02-16-2022, 01:41 PM.Leave a comment:

Re: Modern Samxon and Teapo caps much better these days?
Totally agree.
It's incredible, a friend has an i7 3770 with an ASUS P8H77-I motherboard, the pc has 80,000h, and no Apaq has yet failed, and he plays with that computer almost every day.
The most incredible thing is that his old r7 270 has not died either, although this card has about 60,000 hours of use....Leave a comment:

Re: Failed Panasonic FL
Surely it has failed due to the heat, I would add a fan to keep the chipset and the capacitors that are nearby cool.
How many hours does the hard drive currently have? Out of curiosity.
I have a 500GB Seagate 7200.14 series and it already has 78,000h XD.Leave a comment:

Re: Modern Samxon and Teapo caps much better these days?
Apaq 5K series is doing very well in terms of reliability and performance,
Obviously I prefer Japanese FP capacitors, or Os-con, Nichicon over Apaq, but Apaq for what it is, is one of the best Taiwanese capacitors.
About the Samxon (Solids are actually sold as X-CON) brand, the ULR series mounts them on the XBOX and many devices and they are doing very well....Last edited by kevin!; 01-31-2022, 07:51 AM.Leave a comment:

Re: Sacon FZ revival experiment
I did that same experiment with a condenser that shot out the aluminum part, I added water, I put the part of the roll where the plates are located inside the aluminum can, I sealed it, and it maintained the capacity of 300 microfarads of the 400 reais.
But having a water composition much higher than the original formula, it began to lose capacity over time, the plates corrode.Leave a comment:

Re: A Colossal HDD Failure
I update, this Seagate 1BD142 is proving to be very reliable, the last time I photographed it had 61,000.
Also, as an extra piece of information, the monitor that the PC has has almost 50,000h, and I have never changed the CCFL lamps....Leave a comment:

Re: Abit AI7 mosfet overheating
Yes, I replaced the capacitors and it overheats the same, and overheats with any graphics card, even without a card it overheats the same, what surprises me is that the resistance of the 3.3v track is the same as that of an asrock motherboard with the same chipset.
What I'm going to do is replace the mosfet, and I'll put a heatsink on it to keep it cool.
The motherboard itself turns on and displays the BIOS smoothly, only the mosfet overheats.
The truth is that this motherboard is very beautiful, for my Abit they were...Leave a comment:

Abit AI7 mosfet overheating
A few days ago I found this wonder of the motherboard, it turns out that it had 2 rubycon in bad condition, and I realized that around the mosfet it is darker, as if it has overheated, damaging the capacitors, when I turn it on you start to heat, is this normal?
The transistor reduces from 5v to 3.3v for circuits that work at 3.3v, and I don't see anything unusual.
The transistor marked in yellow is the one that overheats.... -
Re: Bad aluminum poly cap on Gigabyte mobo
I do not like Apaq too much, but I'm going to be honest, are not fake and they are real polymers (I have not seen any Apaq spill), and the 5K series is proving to be reliable, a friend has an Asus board with Apaq 5k and the original SSD marks almost 50,000h of use, and the computer continues to operate stable.
And my uncle has in his office a computer with an asus motherboard with Apaq 5k and the original hard drive marks 60,000h (he never turns it off), the most curious thing is that the processor broke, but not the capacitors and...Last edited by kevin!; 05-09-2020, 03:26 PM.Leave a comment:

Re: Fake Rubycons?
Thanks for the advice
I will keep that in mind for the future, because the size of these capacitors is rare.
This motherboard is full of badcaps, all the capacitors have to be replaced. It has all the samyoung NXC capacitors in bad condition, as well as various teapo, and lelon
.
If I think the same, these MFC if they did not get to be in stress conditions, they would have had a longer useful life.
That if the board has worked 44,000h (according to the SMART of the HDD).
The board was...Last edited by kevin!; 04-25-2020, 02:12 AM.Leave a comment:

Re: Fake Rubycons?
I think they are genuine. I recently replaced a faulty Foxconn motherboard with VRM capacitors leaking, and they are also rubycon, but not MBZ, they are MFZ series....Leave a comment:

Re: OMFG, I have real internet!!
Yes, the upload speed I had in ADSL was ridiculous. And that the ISP promised me 640Kbps upload.
It was never fast, plus it always had a lot of ping.
The Movistar client boxes (Owner of the ADSL infrastructures) are mostly poorly closed, they get humidity, water, there were always cuts and problems in the network.
Once I published a photo of a poorly closed box on the ISP forum and the technician came to my house angry complaining that he should not have taken a photo ...
Now with the fiber (the infrastructure...Last edited by kevin!; 03-22-2020, 10:04 AM.Leave a comment:

Re: OMFG, I have real internet!!
It had 600Kb of upload, but it was terribly slow and with many connection drops, and also adding that you have to upload the photo to a server located in the USA (I reside in Spain) the upload width is terribly reduced.
You're right, possibly also because of the network problems with BCN being slower than expected.
The photos that I usually upload are between 10Mb to 15Mb maximum, but I swear it took at least 2 or 5 minutes (depending on the photo), to upload for example 10 photos I had to leave it about 15 minutes on the clock....Last edited by kevin!; 03-19-2020, 11:20 AM.Leave a comment:

Re: OMFG, I have real internet!!
I am surprised that being in 2020 there are still 1Mb connections
.
In 2011, a friend who lived in California only had 1Mb, it seems incredible that there were still such low-speed connections, at that time.
Congratulations Topcat on the new connection, I hope it does not take long to give you at least 100Mb.
Before, I had 20 Mb (I get real 17 Mb) and when the 1Gb fiber arrived with 300 Mb of upload, the change was abysmal, the files were uploaded in a moment.
Before, uploading a photo in Badcaps took 5 minutes per...Leave a comment:
