    Paper on VRM filtering caps

    This paper helps give an understanding that different filter caps are required at different stages between the motherboard VRM and the CPU. In addition it demonstrates how ceramics can cause voltage spikes(ringing) and that this can be improved by using the new tantalum polmer caps.

    I remember member called Trodas who tried ceramics at the output of the VRM and did in fact get voltage spikes (ringing). Care and understanding is required when experimenting.

      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?...

      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:

      Replacing electrolytic caps by solid caps on old motherboards
      by madscientist750
      I do have several old pc motherboards which i recapped 10 year ago and some of those caps are bulged now.
      I would like to upgrade them using solid capacitors. I do use them for testing and helping some alternative operating systems.
      I would like to ask if such an upgrade can be done, what should i have in mind when replacing electrolytic by solid caps and if such thing exist, if there are caps list for old motherboards. I would have to figure out what caps needs each motherboard and then prepare a list to try to ask for them on some electronics stores.
