Best Electrolytic Capacitors – Theory & Methodology

Capacitor Performance Database

*The best cap is used as a reference: 100% performance rating

The Chemi-Con KY caps have top specs, and indeed, as you can see, their capacitance is close to the values reported by the factory, while the Teapo and Elite caps have notably lower true capacity. That said, the deviation in performance between the two KY samples I tried is notable, while this is not the case for the Elite PF caps, which top the chart! Moreover, the first Teapo SC cap I tried also has a notable difference from the second one, but the first was removed from a broken PSU, so it wasn’t brand new. Nonetheless, I kept it in the database to show you the difference that a brand-new and conditioned cap can have from a used one. The Chemi-Con W cap was also removed from a working PSU but still performed well.

I am far from having a complete picture of cap testing, and I need to test all of them that I got from Seasonic, the only brand so far that supported me in this new endeavor. I thank them a lot for that!

Electrolytic caps are the essential ingredient for a good PSU. To check the PSU offerings, read my Best ATX v3.x PSUs article before investing in a new power supply.
