    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.
