Summit 2026 - Achieving 80 PLUS Certification: Precision Efficiency Testing for Server PSUs

Register Here

As power densities and efficiency targets continue to rise in data center and AI servers, accurately measuring the efficiency of server power supplies is becoming increasingly challenging. At efficiency levels above 95%, even small measurement uncertainties can determine whether a design meets 80 PLUS certification requirements.

This session from Rohde & Schwarz explores where conventional measurement approaches reach their limits and how precision power analyzers can enable reliable determination of true input and output power under distorted waveforms and dynamic load conditions.

Through practical measurement setups, application-focused parameterization and example results, the session highlights key challenges, uncertainty considerations and best practices for robust power supply efficiency verification.
