    Starting to think OST caps are the new fuuhjyyu's

    Seems like every PSU that I have opened up lately for autopsy that uses them I find at least one or more of them bulging or vented.

    Based upon my observations, I am officially deeming them in my non-official capacity for capacitor performance ratings "replace on sight".

    End of rant.

      Hhmm. Then how do you rate Teapo? Better than OST but not as good as Made in Japan caps?

          Havent seen any obvious failures with them that I can recall off the top of my head... at least in PSUs. Thats not to say that they arent venting from the bottom or failing in some other manner. Same goes for LTEC.

              OST aren't as bad as Fuhjyyu but to me OST are 'replace on sight'.
              ESPECIALLY in a PSU or a VRM.

              Teapos fail in PSU's only occasionally.
              OST fail often. [No matter where they are...]

              Teapo got a bad name on older motherboards [socket 370 vintage] when using them in 1000uF and up was not too uncommon on "middle-class" and below motherboards.
              They didn't do well there. The bigger they were thew worse they did.

              Beginning about the era of early P4 Teapo on mobos usually only showed up as 1000uF 8mm and smaller sizes.
              They did better when max was 8mm 1000uF but still not well.

              The small 4 & 5 mm have never been a 'common' problem.
              Those hardly ever fail.

                  I've never seen a motherboard with OST that did not fail, but I've never seen a PSU with Teapos that didn't fail either. I haven't had good luck with Teapos in PSUs. The question is, did they fail because they were poorly made, or because their endurance was none too great. In the PSUs with Teapo, they were in computers that were either very old, or newer computers that were left on 24/7 in MiniATX cases.

                      Not had any problems with OSTs on either motherboards or PSUs. No problems with Teapo in PSUs but a few cases of the big caps failing on old motherboards in the VRM section. Newer ones, smaller caps, no problems.

                          Most of the time when I see bad Teapo in a PSU it's a lower end PSU that's 'light' on OP caps to start with.
                          ['Light' meaning either too few or not enough uF.]
                          Suspect the Teapo used are under rated for the job in the first place.
                          That's the PSU mfr's fault, not Teapo.

                          I rarely see a bad Teapo in a decent PSU.

                              Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                              by momaka
                              I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                              For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                              It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                              Heathkit IO-4205 Power Supply Caps
                              by eryjus
                              Hello,

                              First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                              I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                              I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                              ...

                              Lenovo ThinkPad P1 Gen 3 (LPM-3 19770-1) not starting, only Caps Lock Light turning on
                              by Basileus
                              Hi, i just received this P1 gen 3 and started troubleshooting it, and im encountering a very bizzarre behaviour which i cannot find any info or example about:

                              The laptop doesnt turn on, you do get amber light on the charger led and both the power button and lid led blinks 3 times like described on the manual when the machine is plugged into power. but nothing else. Same behaviour when trying charging when either of the two usb-c ports or the proprietary DCIN connector.

                              I proceeded removing cmos battery and main battery to try and see if it would change anything, but nothing....

                              Identifying caps on an old Zoom 9000
                              by Paxman_Swede
                              Hello!

                              I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                              The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                              I have studied the board and...

                              Help with switching power supply caps
                              by captain150
                              I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                              I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
