Overview

Test Phase 1: Increase load from 20% to 100% of nominal power rating in several steps (appr. 5 hours) Test Phase 2: Steady load at 100% of nominal power rating (appr. 19 hours) Test Phase 3: Measurement of voltages on rails, ripple, noise level, temperatures, efficiency (live broadcast during the test, values at the end of phase 2 are being published)
The Details
Failed Or Passed?

We say that a PSU has failed our test battery if any of the following happen:
