Re: The Hall of Shame - Badcaps Photo Montage

The font on those “Nichicons” is definitely dodgy, although I’d be curious to see if the bung is accurate or not. My guess is that they are most probably counterfeits as well.

Re: best cheap/free scores 1.1

I’d say they’re equally bad, but the lower voltage parts on the VRM output (2200F 6.3V, 1500F 6.3V, and 3300F 6.3V, etc) or those scattered amongst the board (1000F 6.3V in NXC’s case and 820F...

Re: The Hall of Shame - Badcaps Photo Montage

I forgot to mention Tayeh and Arcon on that list of utterly crap brands. I could only find a mention of Yihcon on Chhsi’s most recently accessible web archive snapshot. No mention of Fuhjyyu, but...

Re: The Hall of Shame - Badcaps Photo Montage

Are you referencing Chhsi capacitors (Cheng-Shing Electronics)? I dont think theyre one in the same regarding Fuhjyyu, but they were definitely among the worst of the crapacitor plague brands back...

Re: The Hall of Shame - Badcaps Photo Montage

I think LTEC just went from iffy to utter crap over time.

As to Fuhjyyu, well... this is an example of why Fuhjyyu has such an unfavorable reputation:

Re: The Hall of Shame - Badcaps Photo Montage

Delta actually design their PSUs such that the output caps are not stressed. That’s how lesser esteemed brands such as LTEC and Taicon can survive in very old Delta PSUs.

It’s not uncommon to find...

Re: Seasonic ss-520gb 520 watt voltage drop and bad voltage regulation

OST and Teapo are actually notorious for failing without visible signs. That said, I’m surprised the culprit were the NCC caps - it looks like they used good series (KZE, KY, KZH, or something...

Re: The Hall of Shame - Badcaps Photo Montage

Sanyo’s WF series has issues with long-term reliability. I would not deem Sanyo (Suncon) a bad brand just because of that one series. I’ve seen quite a few ECS motherboards from 2009~2010, loaded...

Re: The Hall of Shame - Badcaps Photo Montage

Well, compared to KZG, WF, and the very early HM/HN at least, I found that MCZ was far less failure prone. I lost count of how many motherboards I saw bad KZG, WF, and HM/HN on whilst the MCZs (on...

Re: Recapping Mean Well MWP-606

The 3M prefix denotes their Indonesia factory. The S prefix denotes their Seibu factory in Japan. The factory and datecodes look legit to me in accordance to the attached image.

Re: A8N-SLI Premium full recap gone bad

So, it looks as though you installed the replacement caps backwards (several have vented). :D On ASUS boards, the shaded side of the polarity circle is positive rather than negative. :lol:

Re: The Hall of Shame - Badcaps Photo Montage

Re: XFX GeForce 9600 GSO [PV-T960-SDFH V1.4] recap info

Neither. The 3300F 6.3V KZG you decided to use on that card will fail first. :group: (unless it was manufactured after 2007)

I would guess the caps in the good bag lasted longer than the caps in...
