Efficiency Normal, Light & Super-Light Loads
The efficiency is low in all areas, and the power supply does not achieve more than 70% efficiency at a load of 2%. It also does not reach the 60% required by the ATX specification. This means that the PSU does not meet the appropriate ATX v3.1 specification. I will ask Deepcool to send me another one for a retest, as it is a shame that it performed so poorly in this test, even though it passes the demanding transient response tests with flying colors.
Average efficiency
The average efficiency of the platform is low, especially at 115 V.
Average Efficiency 5VSB
The 5VSB rail is pleasingly efficient.
Vampire Power
Vampire power, also known as standby power or idle power consumption, refers to the power consumption of a power supply (or other electrical device) when that device is turned off or in standby mode but remains connected to the power supply. Although the device is not actively being used, it continues to consume energy, which can lead to unnecessary power consumption and higher electricity bills. The value here is pleasingly low.
PFC (power factor correction)
A power factor correction filter increases the power factor reduced by the distortion reactive power because it reduces the proportion of interfering harmonics and thus also the mains load. The APFC converter should be further optimized for higher PF values at 230 V.
