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: Illegal narcotic substance in electrolytic capacitors

Thats interesting regarding FC. In accordance to the Panasonic FC engineering draft, the contents, however corrosive they may be, should not be flammable, even though the series uses the organic...

Re: best cheap/free scores 1.1

Heres another example (https://www.badcaps.net/forum/showpost.php?p=819982&postcount=16) of the 820F 6.3V KZG bulging on the shelf. And yep, the 3300F 6.3V KZG made before 2008 are the most likely...

Re: best cheap/free scores 1.1

The 820F 6.3V KZGs never bulged in storage!? Momaka (https://www.badcaps.net/forum/showpost.php?p=613654&postcount=700) and Agent24 (https://youtube.com/watch?v=5YNHFq5IiGQ) beg to differ. :goofy:...

Re: Biostar N7NCG 400 v7.2

Or maybe the OSTs parameters (ESR, capacitance, leakage current, etc...) just degraded over time (which is quite possible given the previous memtest errors), if the specs of that batch werent...

Re: Illegal narcotic substance in electrolytic capacitors

GBL is a solvent long used in non-aqueous capacitor series such as Nichicon PW, Panasonic FC, Chemi-con LXZ, etc. Unless the capacitors vent or leak their contents, or someone actively tries to...

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

KZE is a series by Nippon (United) Chemi-con. They are usually known to be good capacitors. It’s the KZG (easy to confuse with KZE) and KZJ series that are known to be wholly unreliable. As with...

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...

You noted in this (https://www.badcaps.net/forum/showpost.php?p=573161&postcount=53) post, over 3 years ago now, that you had just such a 1000F 6.3V 8mm Teapo SC bulge in storage. Or did you forget...

KZG never fail to well... fail. :lolsign: :lolsign: Only Sacon/GSC, Rulycon/Jee/YEC, and some really dodgy brands that gained notoriety in the early 2000s (Chhsi, Jackcon, Fuhyin, etc) actually seem...

Re: Polymodding Asus A7V266-E, Capacitor Recommendations?

Re: Help with Sprague cap replacement

Re: Swapping japanese/generic electrolythics with solid-states

I believe the ASUS A8V model is closer to fourteen years old, possibly not even that. I’d guess the board was made around the latter half of 2004 / possibly early 2005, and those MBZ appear to use...

Re: Dell Precision 470 Workstation

The Nichicon HDs in the Hipro PSU also appear fine. This is why mixing crap caps and good caps is an unwise practice. It would be interesting to diagnose why the original Delta PSU failed (as I...

Re: The Hall of Shame - Badcaps Photo Montage

Ive seen many Suscon fail in LCD monitors, and bulging and leaking Suscon arent a stranger to me in older Hipro PSUs. So I would not rank them much higher than Teapo/CapXon/LTEC. Elite are also...

Re: The Hall of Shame - Badcaps Photo Montage

Those findings aren’t consistent with mine, actually.

In many GPS-350 series units, for an example (made in 2005 or thereabouts), I found that it’s always the CapXon GL on the +12V rail (or +5VSB)...

Re: 400W PSU... is it worth trying to repair?

Between those heatsinks and the 470F primaries, etc, I highly doubt that PSU could do 400W. More like 250W, or as the other supply expressly states, 235W. That Teapo definitely needs replacing, but...

Re: EZ-Cool ATX-650JSP ATX PSU recap.

Not sure if I agree with that.

The older Panasonic FJ/FL and Rubycon MBZ/MHZ were generally very reliable capacitors, at least compared to the likes of KZG/KZJ. And Nichicon HM/HN/HZ made after...

Re: EZ-Cool ATX-650JSP ATX PSU recap.

I want to reiterate what momaka said about Chemi-con. So long as you stay away from KZG and KZJ made between 2001-2007 and TMV and TMJ from that time period, and so long as you don’t reuse certain...
