I would like to start a thread of devices maybe to avoid because of the brand of capacitors used. I just opened up an addtronics p4 350w psu Model ENP-0735 and found it packed with TEAPO caps :cry: . Supposedly a premium psu, not used much because the fan is very powerful and noisy.

looking back, i guess it wasnt such a good idea
:o
anyway i am going to list some stuff anyway, also consolidate some of my other posts. I will list devices with good caps and ones with potential bad caps. It was bad to say avoid these products without seeing an actual failure.
GOOD
HP DL380 G4 Server - Sanyo OS-Con on motherboard, Nichicon and Rubycon in PSU
Cisco 2950t 24port switch - Nichicon on board, PSU has some dodgy looking ones
BAD
Zyxel ADSLoPOTS router - Hermei caps (nasty values also 1000uf 25V and very crowded, a difficult recapping if required but an excellent router)
Zyxel GS-1008 8 ports gigabit switch - Supacon caps

Hi all!
HISENSE 65E7KQ PRO
RSAG7.820.13512 - chassis
MT9618BAATAB - cpu
RSAG7.820.12059 - power

KLM8G1GETF - emmc
The TV does not turn on, the standby indicator is on. All voltages are present.
Emms is dead. Not readable, not detected.
Replaced emmc.

These cheap non brand capacitors at it again
Last night we had a power outage [ long drawn out trying three to come back up before going out completely ] and when I went to turn the DVR camera recorder back today no go 3 bad capacitors ( one capacitor no ESR reading on DVR board the other 3 capacitor on the power supply board over 40 ohm this is not a misprint ) on the external switching power supply and one capacitor on the DVR camera recorder board where the power supply that goes to the hard drive disk is
Well at least I have the cameras back on line I to try the... -
This is my son’s cooler for his semi truck for his drinks the other day it started short cycling ( running for a second or two then shutting down ) and restarting four or five times then going into an error power cycle the controller then it would do the same thing again
Found a 47uf@63 volts double the ESR value of a new one
The 220uf@16 volts same as a new but 220uf@35 volt replacement capacitor
The main filtering capacitor was not replaced because I did not have that was not too tall
Where the 220uf capacitor is some type of switching power...08-30-2022, 05:28 PM -
Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor...
