Anything worse than GSC???
Maybe, somewhere, there's a capacitor brand that's even worse than GSC. In fact, I doubt there isn't. Any examples???

Maybe Canicon or Sacon... -
Re: Anything worse than GSC???
Sacon is another name for GSC. I don't know about Canicon.Comment

Guys,
GSC, evercon, and sacon IIRC are one and the same.sigpic

A failed GSC... Okay, CapXon... seriously, I've replaced more of those than any other capacitor in TVs and monitors. Rubbish!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Anything worse than GSC???
GSC/Sacon is the worst IMO. Fuhjyyu is a close second. Teapo is probably next.I love putting bad caps and flat batteries in fire and watching them explode!!

"Chhsi" seems to be as bad.

Re: Anything worse than GSC???
The absolute worst is Rulycon (the fake Rubycon). The eletrolyte in those caps will break down regardless of whether they are run near their limits or not. In fact, they will go bad without being used.

BIG GAP

Second place I award to Stone caps. They will bulge at the slightest presence of heat.
A not so distant third, I would say Sacon FZ and maybe Evercon too (but not GSC). While they may be the same company, GSC *at least* don't go bad just by sitting around and they don't make a loud popping sound like Sacon FZ does when they fail.
I still have a Jetway N2PAP-LITE motherboard (circa 2003) with the original GSC ME caps. Works fine. I use it every now and then to test hardware and play some older games.
Fourth: CapXon. Heat them up a bit, and they'll hatch.
Fifth: All other crap caps. I don't consider Fuhjyyu that bad. Sure there were lots of failures in the early Antecs, but keep in mind that those older Antecs had retarded fan speed controllers, so it's not all Fuhjyyu's fault.
I have a Macron Power MPT-301 PSU that originally had all Fuhjyyu caps. Got it for free because the fan was stuck. The stuck fan caused some serious darkening of the PCB near the secondary heat sink. Guess what? - Those Fuhjyyu caps that were near it were bulged, but those that were a bit more far away were not. I fully recapped this power supply in 2008 or so. This year, I finally tested those Fuhjyyu caps. The bulged caps obviously tested bad on ESR, but the non-bulged ones tested fine - that's nearly 4 years after they have been pulled out of that power supply. So Fuhjyyu is far from being the worst.Last edited by momaka; 05-08-2012, 09:31 PM.Comment

Re: Anything worse than GSC???
Nothing a resistor can't fix. See my post on a fan mod and recap of a SmartPower 2.0 350w.
But yah, the way they come set up from the factory is pretty bad. It causes them to run hot even under a light load, putting similar stress on the components as running it at near 100% all the time.Comment

Re: Anything worse than GSC???
My mom has a boombox with a mixture of Rulycon, Jackcon, and an assortment of unknown no-name caps. The Jackcon caps had failed, but the rest were still good.
I have an old ISA card with GSC caps on it. I don't know how old the card is, but the caps are still good.
The worst caps I have seen are Jackcon, these, and "SS" brand caps, as shown in the pictures below.Attached FilesComment

Aren't Viva pretty terrible too? And CapXon are pretty bad but seem to do decently in power supplies.Comment

Re: Anything worse than GSC???
Nope.avi
Open up any recent (past 5 years or so) Fortron ATX PSU, or one based on a FSP (like almost all Zalman, most be quiet, some Cooler Master, ...). You're guaranteed to find bad CapXons, even if the unit isn't even 2 years old..
Same thing happens in a lot of LCD monitor PSUs.
CapXon seems to be the modern capacitor plague for PSUs of any kind, much like Sacon was (is?) for graphics cards.. (or Fuhjyyu for Antecs)
They'll last a bit longer than 1 1/2 years till they start to bulge. By the time the 2 year warranty runs out, it's just a matter of weeks or months till the device stops working properly.
For recent Fortron PSUs, it seems like there's always a 25V 100uF cap in the 5VSB circuit that dies first, preventing the PSU from starting up (ticking or completely dead). Most of the time, some of the secondary side caps are already puking as well (oddly enough, the ones on 3.3V seem to go first)
edit: @ lti: that's not an ISA card.. that's the controller board out of a CD-ROM drive lolLast edited by Scenic; 05-09-2012, 11:31 PM.

Re: Anything worse than GSC???
CapXon are the worst in power supplies! Never, ever say they are good!!! I have pulled loads of them from LCD TVs and computer PSUs. They bulge like nothing else after about 2 years. They are completely incompetent when it comes to engineering a good cap.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Anything worse than GSC???
Has anyone here seen CapXons bulge if used as primary capacitors in PSUs or just on the secondaries?Comment

Re: Anything worse than GSC???
Not in my own equipment (I don't like CapXon and I replace CapXon primaries when possible), but if you have a look around the Audio forum here, you're bound to find more than a dozen amplifiers with bad CapXons on the primary.
Also, IIRC, there was a picture somewhere (not sure if on badcaps.net or elsewhere) showing the 2 CapXon caps of a PC PSU completely burned, and it wasn't the MOVs or anything else that caused it either - it was the CapXons.
CapXon caps also like to go O/C or high-ESR when used on the primary of a PSU with APFC.Comment

So after using capacitor bungs to repair the rubber feet on two laptops, shown here:
https://www.badcaps.net/forum/showpo...&postcount=548
… and here:
https://www.badcaps.net/forum/showpo...&postcount=585
… I was inevitably left with some paper rolls and cans from the Sacon FZ capacitors I “sacrificed”.
The paper rolls from these Sacon FZ caps looked absolutely bone-dry. The idea then occurred to me: what if I put a few drops of water on there? How (if at all) would that affect these already-failed capacitors?... -
Hi,
I'm trying to resurrect a LG OLED C1 TV that has some panel banding. I used the TCON error bypass to get a picture. I was able to update the firmware as well. But when I performed a pixel cleaning to try to get the banding out, it made the image significantly worse. I tried to undo the effects of the pixel cleaning by performing a factory reset and IN_Stop, but that didn't work. Any way to reset pixel cleaning data?... -
This printer started to usually print the first sheet output of the day with back streaks / blotches. After the first sheet, the print would then be relatively clean. I did the corona wire cleaning but it didn't really help as the next day, the same result. Now after some cleaning of the black drum (with some alcohol and cotton), it has gotten worse to the point now it prints "ugly" all the time. :-(
Is the toner just done or have I ruined the drum during my effort? System indicates the drum has about 60% life, toner 40%.
The attached picture shows the poor... -
I'm finally recapping my Soyo K7VX6 motherboard (aka KT600 Dragon Ultra) and replacing Sacon SZ-series caps. The Sacon SZ datasheet provides a spec for tan delta, but not for ESR, while the candidate replacement caps are specified in terms of ESR.
I found this nice little description of the conversion:
Calculating capacitor ESR from Tan(delta)
https://forum.digikey.com/t/calculat...-from-tan/2633
It mentions that a general spec for tan delta has to be adjusted for the specific capacitance before plugging tan delta into the formula... -
I thought my tv power supply was stable. It's been stable for a few weeks since I swapped in nichicon, united cc, panasonic caps to replace the cheap china caps.
But today it caused my tv to have a flickering spasm again.
what a letdown.
I swapped back my backup power board which has cheap china caps, and the tv backlight stopped flickering.
Sometimes these high quality caps just don't make things better.
