What are these caps?

Re: What are these caps?

I think it is time for an lawsuite against them, it seems to me that they need to suffer substantiall loses to learne the lesson.

Antec isn't the one putting Fuhjyyu in their PSUs... you'd have to go after Channel Well, the OEM actually building the PSUs with these caps.

Re: What are these caps?

Some truth in that OK Wolf but Antec has $queeezed CWT...Hard.
Not all CWT built units have fudge-yous in them...Do they?
I've had some heated open discussion with AntecCSR (cust.service rep.) on another forum. GRrrr! :-)

I have 3 of them sitting here - actual CWT labeled units. Nothing but Fuhjyyu in all three. Well, that's what they did have... two have been recapped with Chemicon and Panasonic. The third wasn't worth the bother to recap.

To be fair, I spotted the odd Capxon and Teapo in them too.

Re: What are these caps?

johnny, in the typical two 200V caps in series voltage doubler circuit, if one shorts or is shorted by another component, the other will probably blow. In parallel with each of the caps is an MOV. MOVs gradually deteriorate, so if it was a P/S with lots of hours of usage, maybe one MOV shorted, causing the opposite cap to blow.

Re: What are these caps?

Well in my opinion it is absolut no point if CWT or other PSU maker are using same crap caps. But as i can see, the major brands in high end PSU`S are all at least using Capxon or Teapo, which is not perfeckt but far more better than any Fuhjyyu crap, which will fail realy early (but probably not obviousely, as more ripple will be tolerated for some time by the other caps in usuall PC system, degrading them ).
I understand, that for an 10$ factory left psu like most oem units probably are, there is no marging for good caps (regardless of the manufakturer), but in an 120$ unit which will be advertised to high end systems i have somhow zero tolerance for that practise.
And even in many cheap FSP oem units, i`ve got from ebay new for about 20€ there are at least Teapo or Ost caps in, which for me had never failed up to now (except some Ost at the 5v SB on most Seasonic SS300FS to SS400FS) in an well build PSU.
I feel not mutch sorry for Antec there.
And i hope, that Seasonic will earn the honor for their good practise. Even if not all of those S12 units has Japaneese Caps in there (at least Teapo), they at least not are failing that often and early like Antec.

Re: What are these caps?

Well, apparently Fuhjyyu/Antec is notorious around the world.

I saw a Wintech built X2 PSU with Fuhjyyu primaries (Koshin secondaries.) I flipped out and asked him how he could let Fuhjyyu's into a build.

His response was the same as you guys:

1. The primaries rarely fail unless provoked by another problem. In which case, any brand cap would fail.

2. (And he said this without me mentioning CWT or Antec) Wintech has pre-assembly quality control that checks each component for proper value, etc. So caps are tested for leaks, proper uF rating and are ESR tested. CWT components are unpacked, put directly into bins and handed to the ladies for assembly ("Women are easier to control." I love that quote.)

Despite this, I still told him to make sure any builds I request have at least Teapo, but preferrably Nippon Chemi-Con. But seeing how it's taken me four months just to get a PO cut for my 800W PSU that still won't see the light of day for another month, I wouldn't expect anything spectactular out of me in this decade.

Re: What are these caps?

Adding that my Channel Well ~350w PSU (CompUSA 400w, 15a 12v) is all Teapo inside.

Do even the newest Antecs still have Fuhjyyu? You'd think with all the warranty returns that they'd go to OST at least...

Check the photos of the TP2-550W PSU above. Not even a year from manuf date and all Fuhjyyu's on the secondary.

I'm cool with Teapos in a PSU. I would think if Antec wanted less problems and want to continue to use a manuf that doesn't do pre-assembly QC that they'd use something that had lower RMA to begin with.

Teapo's far from perfect, but they're WAY better than Fuhjyyu.

If they're using 10s of thousands of the caps a month, I'm guessing that they're sample testing - a few from each box - not 100% testing every lytic they use. Whether sample testing or 100% testing, that would have to be an incredibly bo-o-o-oring job (though it would beat passing out resumes).

Re: What are these caps?

Yeah. I'm sure it's sample testing.

And yes... still a boring job.

Re: What are these caps?

But htere are some options to let a maschine do the job. Any manufacturer will do this for a addiitional price tag. Any cap will be formated with elektrizity (for wich they have to conected to two terminal), therefore ther are lineups to make 100% automatic testing.
E.g. Frolyt is selling any maschine for any purpose thesting caps. If you order from them caps, you can specify the whole setup of production, 100% testing too. But of course, only in quantities and not at the rate any Fuyhio crap cost.

Good to know. So the only physical labor is probably loading up a hopper that drops the caps into place.

Re: What are these caps?

The hoper could be a monkey , but some money has to spend to either pay for the testing or buy the machine assemlby.
