Efficiency Normal, Light & Super-Light Loads
Efficiency is decent at normal loads, but low at light and super-light loads. Efficiency above 70 ei a load of 2% would be nice.
Average Efficiency 5VSB
The 5VSB rail achieves high efficiency at 115V, but does not perform as well at 230V.
Vampire Power
The power that a power supply uses in standby mode is called vampire or phantom power, because it is drawn without the power supply doing anything. This power is usually lost through the 5VSB circuit of the power supply. Vampire power is low at 115 V, but quite high at 230 V.
Average efficiency
The average efficiency is not among the highest in the Gold efficiency category.
PFC (Power Factor Correction)
A power factor correction filter increases the power factor reduced by the distortion reactive power, because it reduces the amount of disturbing harmonics and thus the mains load. The APFC converter works properly.
