    VIA P4PA-UL Bad Caps

    Hey folks, I bought the subject mentioned mobo about a year and a half ago. It was fine for a while, but then it started rebooting itself. I thought it may be a voltage issue so I turned the voltage down. But it didn't make any difference.

    Then about two months ago it wouldn't do a proper restart. Sometimes it wouldn't restart at all, other time it would start the process at post but then it would just sit there spinning the hard-drive, at which point i'd have to hit my reset switch to boot it properly.

    Then just last month I looked at my mobo and discovered two bulged and leaking capacitors right next to the CPU. So I imediately dismantled my machine and i've been searching for new/better capacitors to replace them with ever since, believe me, around here they're hard to find.

    Anyway, I was just wondering if the caps on my board have been blacklisted. They are manufactured by a company called GSC, the whole mobo uses this companies caps.

    GSC is a very commonly known crappy cap! MANY companies used them, and I'm sure that now they wish they didn't. If you plan to recap your board, replace all caps 680uF and up.

      Yeah, the two that went were 3300uF. I'm just gonna bye a new board though, since the P4PA is a pretty old board now. I'll hang onto it though for a future project or something.

      I just wanted to know if GSC was blacklisted. Thanks for the help.

        Re: VIA P4PA-UL Bad Caps

        Me too
        Not only it's full of bad caps (GSC)

        Someone tried to replace some of them with totally unsuitable caps (1500uF/16V -> 1000uF/10V on 12V, 3300uF/6.3V -> 1000uF/10V...)

        Someone also scratched the PCB, breaking 3 traces

        And even inserted memory backwards, destroying this diode


        After fixing the traces and replacing the diode and caps, it works. Sometimes - depending on CPU heatsink movement. There's probably a bad solder joint under the CPU socket (SMD)...

          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).

          https://www.badcaps.net/filedata/fetch?id=3591772

          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."

          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,...

          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?...
