  1. Interesting list. Can you please tell us a little how did you determine they are crap?
    Personally I am a bit tired of changing caps in power supplies and I was thinking of getting an ESR meter but maybe you know a better way. Besides the capacity and ESR is there something else to consider?

    • 360customs says:

      Capacity and ESR are a good indication when you can compare to genuine parts and have vendor data available. “Fakes” can be found when comparing like venting hole pattern, sleeve color, fonts, geometrical dimension. Not saying, they’re all “fakes” but their are “fakes” around. These mostly fail within the first hours of operating or getting hot/venting.

      If they measure okay/good, it’s up to you if you thrust them in the application intended.

      Regards, Christian
