    Has anyone seen these caps before?

    Yesterday, I was given a used PC that failed to POST, no video and no bleeps.
    I didn't reject when I saw it, because the case looked good, saw and pulled a SoundBlaster Live sound card from it and installed it into my PC. Also had an Athlon T-bird 1.4 ghz and Kingston PC2100 DDR SDRAM with Nanya chips.

    The Athlon T-bird 1.4 ghz processor does work.

    It has Ost caps that also say "IQ" on them! Like if Ost aquired I.Q.!

    The Ost caps have the following text on them:

    OST

    IQ

    6.3V

    2700uF

    RLF 105C

    --------------------------------------------

    They have a green wrapper with gold text.

    No bulging.

    No leaking that I can see.

    The thing that interests me is that the Ost caps also have "I.Q." written on them. I thought that Ost and I.Q. were separate cap brands!

      Re: Has anyone seen these caps before?

      amusing quote from the wikipedia

      'OST' is also the abbreviation and mark of the Taiwan Ostor Corporation, who commonly make Alumunium Electrolytic Capacitors (http://www.ost.com.tw). They are an accepted and well known "crap cap" brand, i.e, a company who's capacitors are sub standard.
      search has revealed no data on IQ caps or OST/IQ relationship

      sweet FA as the english say (stands for Fuck All....)

          I wish I can still know exactly why the motherboard fails to POST.

          It's still getting power when I turn it on. Just nothing else happens. Thus I did check to see if the processor was bad, but apparently, probably not bad, because another motherboard POSTed with that processor. I did that check, because a damaged processor can cause the motherboard to fail to POST with no bleeps.

              It also has caps that just say "I.Q." and G-Luxon caps. All of the caps appear to be fine.

                  Both OST and G-Luxon have been known to fail with no outward signs. I inderited an Abit BE6-II that wouldn't POST, beep, or anything. Upon inspection, 20 of 22 caps (Jackcon and Teapo) were visibly bad. Replaced them all, and the board works better than new (all voltages are rock solid). Chances are better than good that your board will work just fine after a complete re-cap job, as long as you take proper care in doing the job.

                      Actually, I never saw Teapo caps visibly bad.

                          Me too. I even have these in my MSI K8N Neo2 Platinum mobo . The board's in warranty, thus I'm not recapping them anytime soon.

                              IMO, if the motherboard is stable, including Prime95 stable and 3D Mark stable and the caps aren't bulging or leaking, they're fine.

                              Symptoms to look for would be Prime95 suddenly failing when it passed Prime95 before. Or suddenly crashing when running 3D when stable before.

                              Was it unstable?

                                  Sorry, that should have been Tayeh, not Teapo.

                                      Nope, it's working really fine. Just seen some Teapos in a sea of Rubycons and Nichicons and they looked out of place.

                                      Btw, the Nichicon is a HN(M). Hope it won't fail anytime soon.

                                          Hey, glad I searched first!

                                          I discovered this on my own the other night, with a Shuttle (Spacewalker) AI61V12A (AMD 751 chipset, Slot A). I have two of these boards, one with an ECS-type glued-on heatsink, one with a clip-on generic green one. The non-Spacewalker branded board has simply "IQ" capacitors, but the Spacewalker has exactly what RJARRRPCGP described, except the RLX series. They're 6.3v, 105 C, 3300uF.

                                          The board on the left, with the CPU and one stick of PC100, has the glued on northbridge heatsink and the OSTs. The board on the right is unmarked.

                                          Best of all? I, too, got an SB Live! from the Spacewalker machine. Came with a 750 Athlon and decent Radeon 9100, too.

                                          You know there's something wrong when you open up a PSU and are glad to find Teapos.
                                          Why I don't buy cheap cases!

                                              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).

                                              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."
                                              ...

                                              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,...

                                              Gigabyte GA-6OXT :: caps question
                                              by Foetuss
                                              Good evening

                                              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                                              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                                              But I was also suprised about the bigger boys, which are 330µF 25V.
                                              Could it be they used 25V caps because they were cheaper / available at that time?...
