Advice regarding Tagan TG380-U01 recap

[unmei220]

Hello to all. This is my first post here, but i've been around even before I registered.
I have this Tagan TG380-U01 unit which was working fine, but recently I opened it out of curiosity/boredom just to find it was full of Fuhjyyu capacitors, except the primary ones, I think. Also discovered that 2 of the 2200uf x 10v ones were bulging, so I replaced them with........ 2 JACKCON's I had around there (don't punch me, they were the only thing I had around).

Of course I don't want to leave the JACK's and Fuh's in there, so I request if someone can give me any advice as to what caps should I buy to replace all those Fuhjyyu ones. Can motherboard capacitors be used as replacement in PSUs, or are some other capacitors recommended ?
Also, should I replace all the smaller ones ? They're all also Fuhjyuu (for example, there's some 4.7uf x 50v ones amongst others).

The PSU has:
3x 2200uf x 10v
1x 2200uf x 16v
2x 3300uf x 10v
2x 1000uf x 10v
2x 470uf x 16v

Thanks in advance.

Those power supplies get very hot because they try to be very quiet...

Now, if you consider that the caps are Fuhjyyu, you understand that there is high possibility to fail.

If I were you I would fully recap it with Japanese capacitors only.

Re: Advice regarding Tagan TG380-U01 recap

Thanks for the reply. Yes, this unit is VERY quiet, even when the heatsinks start to become very hot, the fans barely spin, so a lot of heat stays inside.

Can I use Rubycon MBZ/MCZ to recap this unit or should I use other type of capacitors ? I read on some threads here that they are not recommended because of the very low esr... any recommendations? I don't know which caps should I put into it (I'm referring to brand/series).
Should I use the same capacitance / voltage as the caps beign replaced ?
Sorry for so many questions.

It's a good unit I think, apart from those Fuhjyyu caps. That's why I want to recap it before something serious happens.

Re: Advice regarding Tagan TG380-U01 recap

i've recapped 2 of these (330/310W and a 380/360W just like yours). Used Panasonic FC and FM. those are a pain in the butt to recap due to the huge heatsinks and general crammed design, but well worth it.

just make sure you replace ALL the fuhhuhfhkhuuhu's ... including the small ones (except maybe the really tiny ones like those on the controller board that sticks up in the 2nd pic)

if you don't care about how silent it is, i'd recommend rewiring the fans to 5V or 7V.. these things get really toasty..

In some cases that's okay but it depends on what the original caps are.
Just saying Fuhjyyu is not enough info..
What series and diameter are the Fuhjyyus?

3x 2200uf x 10v - what?
1x 2200uf x 16v - what?
2x 3300uf x 10v - what?
2x 1000uf x 10v - what?
2x 470uf x 16v - what?

Re: Advice regarding Tagan TG380-U01 recap

Thanks Scenic for the reply and the tips about rewiring the fans, maybe I would do it. It always bothered me how hot the unit would get and how the fans spins so slowly. Also thanks for suggesting the Panasonic caps.

PCBONEZ: sorry, I'm relatively new at this and forgot to put the full details.

3x 2200uf x 10v - TMR series - 10/25mm
1x 2200uf x 16v - TMR series - 10/30mm
2x 3300uf x 10v - TNR series - 10/25mm
2x 1000uf x 10v - TNR series - 8/15mm
2x 470uf x 16v - TNR series - 8/15mm

I hope I wrote that right, as the capacitors are still in the PCB, and I did this by eye.
There's also a "big" capacitor on the little PCB that's mounted above the heatsinks. I can't see it well, but it seems to be a Fuhjyyu 22uf x 400v, MK series, 16x22mm.

Panasonic FK, Panasonic FC and Panasonic FM is what I use to recap power supplies. Since all of the power supplies that I've recapped are quite old, using ultra low esr capacitors such as MBZ/MCZ is really not recommended.

I have never met a power supply that uses MBZ grade capacitors. Modern psus are another story... They even use polymer caps..


A friend of mine gave that Tagan to me:
https://www.badcaps.net/forum/showthread.php?t=12484

Due to extreme heat, every cap on it was dead, I mean every cap, including the 2 big primary caps, Panasonic 85C.

The primary transistors were blown too.

I decided not to recap it, because it would be a very difficult and expensive project (do you know how much those big caps cost?) and the output of my effort would be a 330W Power Supply with a single 18A 12V line...


I don't intend to discourage you repairing yours, I just say that a full recap is necessary, and a mod at the fan controller circuit would help the new caps last...

2x 1000uf x 10v - TNR series - 8/15mm
2x 470uf x 16v - TNR series - 8/15mm

FK,FM and FC are suitable replacements for these caps.

edit: Those are also good and suitable for the job:
https://www.badcaps.net/store/produc...products_id=56
I have never used them, but other forum members like c_hegge have successfully recapped power supplies using these.

There's also a "big" capacitor on the little PCB that's mounted above the heatsinks. I can't see it well, but it seems to be a Fuhjyyu 22uf x 400v, MK series, 16x22mm.

That's the pfc circuit. That cap needs to be replaced. Fuhjyyu are so bad that even their high voltage caps fail...

Re: Advice regarding Tagan TG380-U01 recap

Thanks goodpsusearch for the advice. I saw that thread long time ago, I forgot about it. Yes, the big ones are definetely not cheap, but it seems they're ok in mine. Also, it's very difficult to come across a "decent" PSU here in Argentina. That's why I want to give this one an opportunity by recapping it.

About the Panasonic caps, should I stay with one series ? or can I mix series depending on what ones fit perfectly onto the PCB ?

About the 22uf 400v one, what replacement do you suggest ? I came across some 22uf 450v ones in ebay. Some NCC KMF series and another Rubycon BXA series. Only the BXA seems to physically fit onto the small PCB.

I wouldn't buy off eBay. There's a (pretty) good chance that they are fake. Sometimes you get a good dealer, but a lot of time its counterfeit trash.

I understand. One of the reasons I decided not to fix mine is that I can get as many of these or those as I can for free and as you can see, they are high quality, easy to fix power supplies. I even fixed some and gave them to friends for free!

Try choosing caps that fit perfectly onto pcb first and then try putting caps of the same series and esr. Not very important anyway..

Buying caps through ebay is risky. Big possibility to get fake caps...

Re: Advice regarding Tagan TG380-U01 recap

These are Low ESR
3x 2200uf x 10v - TMR series - 10/25mm - 1220 mA - .039 ohms
1x 2200uf x 16v - TMR series - 10/30mm - 1450 mA - .030 ohms
FC are NOT suitable replacements for these.

These are not Low ESR - but should be...
2x 3300uf x 10v - TNR series - 10/25mm - 920 mA
2x 1000uf x 10v - TNR series - 8/14mm - 460 mA
2x 470uf x 16v - TNR series - 8/14mm - 370 mA

KC8 has posted successfully using 3300uF/6.3v MBZ to replace those damned 4700uF/10v/10mm when he didn't have anything else available.
I think that was before the 10mm RS were available and before anyone was stocking FK.
Probably not the best choice now days but it works.

Re: Advice regarding Tagan TG380-U01 recap

Then, where can I get that kind of replacement for that "big" capacitor ? (I checked here in badcaps store but it doesn't seem to be that kind of capacitor).
On ebay, I searched only members egekecu and audjade_chn. I think I read here in somewhere that those were "trusted" sellers. Maybe I made a mistake.
Even if those sellers sell fake ones, are those ones I mentioned correct replacements for the Fuhjyyu one ?

PCBONEZ: Thank you very much for the data. Then it seems I'm back to square one ? Please, what capacitors do you suggest I should use then ? Can I use the panasonic ones to replace the non-low esr ones then ? It's difficult here to see good capacitors (see, I used 2 JACKCON's in this PSU), so I'm probably (I must) have to order them from ebay or from badcaps store.

Re: Advice regarding Tagan TG380-U01 recap

I came across some 22uf 450v ones in ebay. Some NCC KMF series and another Rubycon BXA series.

unless the ebay sellers are either Audjade_chn or the PC Motherboard Capacitor Store, i'd stay away from ebay caps. too high of a chance to end up with fakes. those 2 sellers above are aware of the fake caps.

edit: okay.. took me too much time to post this one
egekecu = pc motherboard capacitor store
audjade_chn = audjade component shop

i've bought from both of them before. never had any issues so far except one cap with a slight dent in the casing.. but that probably happened during shipping.

Why not?



2200uf x 10v - TMR series - 10/25mm - 1220 mA - .039 ohms
--> FC 10V 2200uF 10x30 1815 mA 0.035ohms

2200uf x 16v - TMR series - 10/30mm - 1450 mA - .030 ohms
-->16V2200uF 12.5x25 1945mA 0.030 ohms

The only concern is whether they fit.

The TNRs can and should be replaced with entry level low esr caps like FC or FK and maybe FM, but I would try to avoid the last ones as TNR replacements.

About the big cap, you can try digikey, mouser, or ebay sellers that scenic recommended. That capacitor is not low esr, general purpose, probably 85C, but you should try to choose a 105C one.

[unmei220]

Re: Advice regarding Tagan TG380-U01 recap

Scenic: yes, those are exactly the sellers I searched for. I read here in badcaps that those were "trusted" sellers aware of the fake caps. Maybe I read a post of yours about it.
About those 22uf 450V caps, I'm still not sure. Are those correct replacements for the Fuhjyyu 400V one ?

edit:
goodpsusearch: then, can I safely choose one of those capacitors as replacement for the 400V one? About the other caps, the only concern would be the diameter, as they're all packed together. There's no problem with the height of those, there's nothing blocking them.

Thank you all for so much help.

[Scenic]

Re: Advice regarding Tagan TG380-U01 recap

these two should do just fine for the 400V 22uF fuhuhufhuf*ckyou cap (well.. if they fit)

http://cgi.ebay.com/300381786398
http://cgi.ebay.com/300456352348

i'd suggest looking for a cap source with all or at least most of the caps available. no point in buying from 5 different sellers or something (shipping costs)

if you go for the badcaps store for most of the caps, maybe shoot topcat a PM if he has the other needed ones too?

edit: you could also ask big pope for samxons, allthough that would require a bit of comparing the ESR and ripple, as i'm not too familiar with those (as in i wouldn't know out of my head which samxon series would be comparable to for example panasonic FM, FK, FC etc.)

[unmei220]

Re: Advice regarding Tagan TG380-U01 recap

Those were exactly the ones I mentioned earlier. Only the BXA seem to fit though. Thanks for your confirmation and tip. If I buy from ebay, I'll probably buy all that I need from that seller.

Re: Advice regarding Tagan TG380-U01 recap

Rubycon BXA datasheet:


Nippon Chemicon KMF datasheet:
https://cdn.badcaps-static.com/pdfs/...a9532291c7.pdf

The BXA series endurance is 12000 hours, while KMF is 2000 for the specific cap you try to replace. I would get the BXA.
