    Needing specifics here. Please advise.

    Replacing caps is no foreign concept to me. I've replaced scores of them...with used, same-rating caps that I can find in power supplies lying around my office, etc. It's worked well enough. I have boards running for 2 years after, etc...

    *presents wrists for the slapping while grumbling 'Hey. It's what I had."*

    That's the problem. Where the hell do I find the correct caps to replace...brand new? I'm aware that certain brands are better, etc. Everyone loves Rubycon, etc. Great.

    But I am not able to really find somewhere to buy them.

    The second issue is that I read about "Ultra-low impedence" and "High-ripple" and realize that people are replacing 820uf with 1500uf @ same voltage, etc. THAT is actually the bigger problem.

    Does it really matter? How do I know what I have to replace? It's not as if the cap says, "Hey! I'm high-ripple!" Y'know?

    Please give me a summary that I can work with...for the love of the gods! I once submitted a request for caps to this site about two years ago...but never received a reply of any kind. Figured I'd try the forums this time.

    Right now, I'm replacing the caps on yet another Intel board. This one came out of a Gateway. It's an Intel D865GLC/D865PESO board. (I generally regard it as the fore.) The Nichicon *shudders* 820uf 6.3v electrolytic caps between the CPU socket and the USB/Printer/PS2 ports as well as one other near the CPU Fan connector are all shot. Need to replace them.

    Otherwise... The board posts and operates. I just won't continue to wear it down under these conditions until I replace the caps.

    SUMMARY:
    1.) Do I need to concern myself with specific types of caps? (e.g. 'High-Ripple' or 'Low-Impedence', etc.)

    2.) Where can I buy the damn things? :P

    Also... I'm not against buying higher-quality caps if they're available...and reasonably priced. (More or less...)

    Pics to follow shortly. (Within 15 minutes.)

    Thanks in advance!

      As an update... Would this be a suitable purchase?

      Yeah. I know. It only took me another minute of looking... But is it CORRECT?

        1.) Do I need to concern myself with specific types of caps? (e.g. 'High-Ripple' or 'Low-Impedence', etc.)
        -
        Yes, however low impedance is not the same thing as low ESR.
        -
        Too low of ripple capacity and the caps will overheat and die early.
        Too high an ESR and they won't do their job thereby allowing the system to run on 'dirty' power. (Full of voltage fluctuations.)


        2.) Where can I buy the damn things? :P

          Yes MBZ would be just dandy.

            Where to buy is found in this forum at: https://www.badcaps.net/forum/showthread.php?t=613

            Rubycon MBZ or MCZ
            Samxon GC or GD

            Both types can be had from forum owner Topcat for US residents. Just ask him for what you need.

            Outside US Big Pope can supply any need.

            Just PM the right one for you.

              Dear Friend,
              Your can buy good capacitors from Hong Kong by mail. It is easy to find good capacitors which capacitances exactly match the replaced. This place has a list of good international shops selling good capacitors.

                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?...
