From September 14 to 28, 2024, the National Technical Committee for Energy Fundamentals and Management Standardization (SAC/TC20) solicited public comments on the mandatory national standard Minimum Allowable Values of Energy Efficiency and Energy Grades for Microcomputers (Draft for Review).

The draft outlines energy efficiency grades, minimum energy performance standards, and testing methods for desktop microcomputers, all-in-one desktop microcomputers (referred to as all-in-one computers), and portable computers (collectively referred to as microcomputers). It applies to general-use microcomputers, but excludes the following types: a) Tablet computers, desktop/rack-mounted workstations, and microcomputers for industrial applications; b) Microcomputers with two or more independent display units; c) Microcomputers with a rated power supply output exceeding 500W; d) Portable computers and all-in-one computers with display screens smaller than 294.6 mm (11.6 inches).

This standard represents a significant revision of the 2012 version. Key changes include the explicit exclusion of tablet computers and a reduction in the maximum rated power supply output from 750W to 500W. The classification of microcomputers has also been updated: previously based on CPU cores, memory size, and GPU performance, the new classification now uses the product of the number of CPU cores and CPU clock frequency. Accordingly, the energy efficiency grade indicators for each category have been adjusted. In addition, the new standard revises the methods for calculating typical energy consumption and conducing testing methods for microcomputers.

Another notable difference from the previous version is the inclusion of a clear one-year transition period in the new standard. While it remains uncertain whether overseas manufacturers will face challenges in adapting, the defined transition period enhances transparency and provides clarity similar to technical regulations in Europe.

Next, TC20 will review the feedback received on the draft and prepare the final version for approval. Given the significant changes compared to the 2012 version, the new standard could have a substantial impact on overseas manufacturers and products. Therefore, it is important for relevant overseas stakeholders to closely follow the development of this standard and engage with TC20 to prepare for future regulatory challenges.
