Electrical performance
Efficiency measurement and no-load consumption
The efficiency measurements taken at the two nominal voltages are seen in the following
tables. The +5 V_SB output was unloaded during these measurements.
Table 1.
Table 2.
The 80 PLUS
computer power supply is. The program defines the minimum efficiency requirements at 20
%, 50 %, 100 % of rated load and a minimum power factor requirement.
According to the program a power supply could be classified in 4 levels:
