grade, TEC (Typical Energy Consumption), and product category presented on the label are determined and calculated according to the standard GB28380-2012.

1.Energy Efficiency 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 specified in the following table:

Product Type

 

TEC (kilowatt hour)

 

 

 

 

 

 

 

 

Grade 1

Grade 2

Grade 3

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 figure presented on the label is the data measured with the representative configuration that covers all the configurations in the registration unit which is selected according to CEL-30. Thus, actual energy consumption of this specific 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 configuration. The categorization of products complies with the regulations in the following table:
