Q&A: 80PLUS | 5% and No Load Testing Report

Introduction

Since its inception in 2004, the 80 PLUS initiative has played a crucial role in driving improvements in power supply efficiency and sustainability. The program initially focused on achieving 80% efficiency at three load levels, which significantly surpassed existing efficiency standards. Over the years, 80 PLUS has expanded its specifications and gained widespread industry recognition. As a result, ENERGY STAR® and the European Union (EU) Energy-related Products Directive (ErP) have adopted its standards. 

The addition of no-load and 5% load tests is the latest development in the 80 PLUS program. These new tests provide a more comprehensive evaluation of power supply efficiency by addressing idle power consumption and efficiency at light loads. These advancements in testing ensure that certified power supplies meet higher standards and deliver improved energy efficiency across a broader range of usage scenarios.
