    Cougar BXM850

    Just picked up a working Cougar BXM850 PSU.
    Noticed that the main input cap is a Teapo LS (420V 560uf).
    appears to be a date stamp on the cap of 09/19 - so is likely to be a bit over 4 years old.
    any recommendations for which cap to use to replace this LS cap?
    Teapo LS spec sheet shows 1600 mA ripple (30x50mm) for this cap. last time i changed a main input cap i used a Rubycon MXK

    i am still looking this over and dont see any other signs of concern. but if someone knows this PSU and has any other recommendations for components to replace, let me know. (secondary caps all look ok but some are teapo. May replace them as well).

    I wouldnt replace it at all, Teapo aren't that bad (2nd tear). but if you really want to replace it you can replace with a 1st tear capacitor of 105 degrees. these are the 1st tear brand capacitors:
    • Rubycon
    • United Chemi-Con (or Nippon Chemi-Con)
    • Nichicon
    • Sanyo/Suncon
    • Panasonic
    • Hitachi
    • FPCAP or Functional Polymer Capacitor (ex-Fujitsu caps segment, which was bought by Nichicon)
    • ELNA

      Thanks for the reply. the Teapo cap is a 105c but still 2nd tear. I have seen what damage can occur when that main input caps fails.
      I know which brands are good. My question was more or less asking what series would be a suitable replacement. Normally i compare the ripple current rating and ESR. But the LS spec didnt seem to list and ESR for this cap.
