Power Supply tests
2026

I have this issue where I like to buy power supplies (mainly from Aliexpress) and test them using my load bank to see if they actually meet specifications!

Below you can find a list (with affiliate links) to the power supplies tests and quickly if they passed or failed. It will be arranged by livestream where it was tested if you want to know more details about a certain model.
