Teapo capacitor quality

Re: Teapo capacitor quality

My atari 2600 from the early 80s has a teapo main cap that still kicking the smaller ones were leaking so i put in nichicon,I think teapos are a great value, yeah sometimes they fail but for the most part they seem to be okay. even most sites reviewing power supplies don't seem to mind them, of course they would like to see japanese caps but if you can get a decent under $50 power supply with teapos then your ahead of the game.

Re: Teapo capacitor quality

Yea I have seen those old 2006'ish PCs still functioning with the Hipro PSUs that have Teapo SEKs... Mind you, I always thought the big Teapo SEKs only lasted because the PCs were lightly used.

Re: Teapo capacitor quality

My Compaq SR5123WM PC with a 250W Hipro PSU has all Teapo caps, are still good! After 7 years of 24/7 heavy use! I never seen Teapo fail afaik. I consider them at best good. Not great but good.

Re: Teapo capacitor quality

Yeah I really liked my Epox boards they always had some of the cleanest layouts, and yes Teapo's really arent that bad, my antec quattro 850 has all teapos for the secondary and it has no problems powering my rig trouble free.

Re: Teapo capacitor quality

I have had a lot of boards prior with Teapo caps, from the Socket 7 to Socket A (mainly Epox), and also power supplies, and they all seem fine, including ones I still have now. Of the few cheapo cap companies I'd trust, Teapo is probably one of them. Ost is the other.

Re: Teapo capacitor quality

I have. 3300uF 16V 12.5mm Teapo SC read 0.33Ω ESR (was not bulging). But generally, yes the 10mm and 12.5mm ones seem to be more reliable

That explains why those PSUs with those Teapos still function. The cap has failed, but not catastrophically like most other inferior caps. 0.33 is still relatively reasonable, especially considering that these PSUs are usually in systems that consume only 150 watts, and the PSUs are rated for 300W+.

I 've never seen Teapo caps large diameter go bad without bulging.

Re: Teapo capacitor quality

you should desolder a few and check the readings. The 2200uF Teapos I was replacing daily were reading 10 - 20uF with no leaks or bulges

Interesting. Were these the 10mm Teapo SC, or Teapo SEK?

Re: Teapo capacitor quality

My 2008 FSP PSU is still doing good, even with Teapo caps.

Nothing like that Deer 250 W PSU.....

Re: Teapo capacitor quality

Stupid, but not surprising. What did they use for replacements?

I forgot the name but it was a brand I never heard of. I remember it was just initials on the cap and it was shipped in yellow boxes with chinese writing.

Re: Teapo capacitor quality

12.5mm and 10mm Teapo SC may very well be almost comparable to top tier brands in terms of longevity. I've stopped doing mandatory replacements of them in PSUs. The 8mm Teapo SC are replace on sight however.

Re: Teapo capacitor quality

Teapos aren't good for longevity. I'd say 5 years absolute maximum.

Re: Teapo capacitor quality

I had a project where I had to replace hundreds of bad caps in psu's of cable boxes and all the bad ones were Teapos. the company was so cheap they gave us another cheap junk cap for the replacements.

Re: Teapo capacitor quality

With a lot more experience now, I can say that probably 15-20% of the Teapo caps I have encountered that failed, failed without showing any visible symptoms.

Yup, they often dry out or out-gas through the bottom bung, similar to G-Luxon. I've seen a fair number of failed Green/Gold Teapo SCs without any visible bulge - mostly from mobos. It's best to replace all Teapos on VRMs and Vcore rails at sight.

Re: Teapo capacitor quality

My 1984 Atari 2600 (PAL) has Wang's caps (enter penile jokes here). The board is stamped 1 JUL 1983, but the chips are later, one being from 1984. Not only that, they are socketed rather than soldered straight to the PCB. Not a surface mount component to be seen!

Unfortunately this console doesn't want to work properly (you'll find this machine on one of my early YouTube videos).

C21: 4.7uF 35V -> [in circuit]
C243: Wang's 2200uF 16V -> 2519uF, 0.04Ω

That's all of them on the entire board (I didn't bother opening the RF modulator section, as that would require desoldering).

I also got a low battery warning on my ESR70 just then and it turned itself off!

** WarninΩ **
█ Low Battery █

Sure enough, the battery is now 9.87V. One original GP Ultra 23AE removed. I might try to zap this one back to life as they aren't that cheap, although alkaline batteries aren't supposed to be recharged (it never hurt any of my AA Duracells and Energizers I did over the years though).

Re: Teapo capacitor quality

got a 1982 4 switch atari 2600 and it has all original old school teapos in it, runs like a champ!

Re: Teapo capacitor quality

yeah teapo is like wal-marts great value brand, you get great value.

Hey, don't knock Great Value. We get their soda crackers imported from you guys to Canadian Wal-Mart and they are much better than Canadian soda crackers.

Re: Teapo capacitor quality

I had good experince with Teapo capacitors I wont say they are excellent but in my friends old computer had teapo caps he had the system running much of the day for 8 or so years before the motherboard chipset went bad, I have the PSU (HIPRO) running in my computer now which is going well... nowdays he has another machine it has a coolermaster unit it is running windows 7 it was one of the last windows 7 stock machines before they went to 8 and i used the rest of his old system for parts. but still those caps just keep on going they could die tomorrow or they could die in 5 years or keep on ticking longer... then again im using it for daily internet and using a old AMD athalon 64 which is well for internet so light load will be fine on the thing

yeah teapo is like wal-marts great value brand, you get great value.
