1. Energy Eiciency Grades
The grade is determined by the standard with the calculation of base consumption level with the sum of
all the allowances for additional components such as main memory and graphics card. For products of
any grade, the TEC should not exceed the value specied in the following table:
Table 3-4 Typical Energy Consumption (TEC) values
Product Type TEC (kilowatt hour)
Grade 1 Grade 2 Grade 3
Desktop microcomputer, AIO Category A 98.0+∑Efa 148.0+∑Efa 198.0+∑Efa
Category B 125.0+∑Efa 175.0+∑Efa 225.0+∑Efa
Category C 159.0+∑Efa 209.0+∑Efa 259.0+∑Efa
Category D 184.0+∑Efa 234.0+∑Efa 284.0+∑Efa
Portable Computer Category A 20.0+∑Efa 35.0+∑Efa 45.0+∑Efa
Category B 26.0+∑Efa 45.0+∑Efa 65.0+∑Efa
Category C 54.5+∑Efa 75.0+∑Efa 123.5+∑Efa
NOTE: ∑Efa is the sum of power factor of product additional functions.
2. Typical Energy Consumption
The energy consumption gure presented on the label is the data measured with the representative
conguration that covers all the congurations in the registration unit which is selected according to
“The Regulation of the Implementation on China Energy Label for Microcomputers". Thus, actual energy
consumption of this specic microcomputer may not be the same as the TEC data presented in the label.
3. Product Category
The product category is determined by the standard according to the microcomputer’s conguration.
The categorization of products complies with the regulations in the following table:
Table
3-5 Product category and conguration description
Product Type Conguration Description
Desktop microcomputer, AIO Portable Computer
Category A The desktop microcomputer and AIO whose
conguration is out of the scope of Category
B, C, and D
The portable computer whose conguration is
out of the scope of Category B and C
Category B CPU physical core number of 2, and system
memory of not less than 2 GB
