Re: K.i.s.s.
Ok. How old were these psu's? I only really see failed teapo in psu's about 6-8 years old, mostly hipros and lower end FSP.

Re: K.i.s.s.
3 years roughly, but a good cap like a rubycon will last much longer than that. I have seen ancient psu's where none of the caps had failed.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: K.i.s.s.
Interesting thread...
How would you rate the following capacitors from better to worse?
Teapo, Ost, Jun Fu, Capxon, G-Luxon, ChoyoComment

G-luxon, it all depends. G-luxon is now owned by teapo, and new ones are simply rebranded teapo. You can tell these because they will have the teapo vent.Comment

Re: K.i.s.s.
so Teapo = Yageo = G-Luxon now?! o.O

Re: K.i.s.s.
I would have said OST and teapo are tied for the best, Capxon in the middle and the others tied for worst.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: K.i.s.s.
Where would you put Jamicon between those?Originally posted by 370forlifeComment

Re: K.i.s.s.
With the bottom ones. I recently opened an AOpen branded PSU made by FSP and the Jamicons were bloated but the fuhjyyu were not. Any brand that is outlasted by fuhjyyu is very very bad IMHO.Last edited by c_hegge; 05-17-2010, 07:49 AM.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: K.i.s.s.
funny thing that i noticed is that the capxon series which fail a lot seem to be the same ones where samxon fails.Originally posted by c_hegge

Re: K.i.s.s.
You also need to take into account the overall design of the PSU and where the caps were sitting. For example, if those Fuhjyyus that c_hegge was talking about were sitting near the vents while the Jamicons were next to a hot dummy-load resistor, then it would make sense why they failed faster. (This is why you see Delta-made PSUs with L-Tec caps last so long - because they are well-designed). And then there's the question which rail was loaded the most and which caps handled that particular rail.Comment

Re: K.i.s.s.
The Fuhjyyu and jamicons were all near each other (ie. very little if any temperature difference), although I didn't think of the other possibilities at the time like the fuhjyyu drying up without bulging or the load on the rails. In any case, though, I still believe the jamicon to be junk, since they would have lasted longer than they did if they were half decent.I love putting bad caps and flat batteries in fire and watching them explode!!

While recaping Antec Earthwatts EA-380 I've broke one side of unknown smd element, it have no print, it's flatter and darker than smd capacitors on this board, shaped more like resistor but it's not resistor ofc. Unfortunetly the printed description was under it and element was glued to the board so I cant read/tell the letter before element number too. Have anyone any idea what it is? Maybe is there any diagram of this PSU?

Although it is far from my main field of interest, people here keep asking me to fix their flat screen TV's.
So far, the problems have generally been on the PSU, the T-Con or the backlights, all of which have been relatively straightforward.
As far as the main board, or SSB, is concerned, the only real issues I've encountered have been bad caps and fucked BGA soldering.
It has also become clear that 'stuck in standby' is a common problem, and something which I no experience with yet could waste lots of time on without an understanding of how the 3v3 is sent to trigger... -
In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
https://www.badcaps.net/forum/showthread.php?t=14159
It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:... -
Hello,
I'm currentlly in the process of trying my first power supply repair (really my first soldering project) and have some questions with regard to which capacitors to replace the bad ones.
The power supply is an Antec Smart Power SL300S ATX12V 300 watt.
I have successfully desoldered every capacitor from the board without destroying anything (I think) and I am currently in the process of choosing which caps to order. This is where I'd like a little community wisdom.
Now the capacitors inside are mostly Fuhjyyus (a forum favorite) with 1... -
Hi all,
Got in these 2 nice PSUs, both died after power surge.
Both seems to be suffering from the same fault.
Blown main fuse
Shorted N mosfet 550v
VP-600P: 5R280CE short between GDS
NE550M: MDF18N50 short between GDS
In terns of board layout these seems pretty identical.
From past knowledge, once gate get shorted, most likely the for the driver to go bad as well.
I never tried to salvage blown fuse PSU with shorted Mosfet due to that.
Is it worth to try and replace the mosfets? is there a chance that the...
