Just in case the OP, or someone else that wants to go down this road, wants to repair this. This is the list I go by. Link first, then list of top tier in case one wants to skip reading the whole thing. https://www.tomshardware.com/reviews/power-supplies-101,4193-5.html All Japanese caps are considered of high quality, and we like to see the following cap brands: * 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 Besides Japanese manufacturers there are also several US and European vendors that make high-quality capacitors. Probably we won't meet any of the below cap brands inside a consumer grade PSU, at least their electrolytic offerings, but we decided that it still worth mentioning them. * Cornell Dubilier (USA) * Illinois Capacitor (Currently owned my Cornell Dubilier) * Kemet Corporation (USA) * Vishay (USA) * EPCOS (TDK company, Germany) * Würth Elektronik (Germany) As a person who has built circuits and such, for long term use I try to stick with Rubycon, Nichicon or Panasonic if I have to. Sometimes if it is a short term project, I'll use 2nd tier. I've had several 2nd tier caps fail. Besides stinking up a room, they can lead to the failure of other components. I replaced two 2nd tier caps in a power inverter not long ago. Luckily it was on the power input and I had the switch turned off. They blew their smoke as soon as I touched the wire to the battery. No damage, just smelly. Good luck to those who tinker. :-D Dale :-) :-)
