Efficiency Normal, Light & Super-Light Loads
The efficiency at normal load looks low in the tables, but keep in mind that most of the power supplies in the corresponding table even have a Platinum and one a Titanium certifications! For light and super light loads, the platform even tops my charts.
Average Efficiency 5VSB
The 5VSB rail has a decent efficiency. Nevertheless, there is room for improvement!
Vampire Power
The power required by a power supply in standby mode is called vampire or phantom power because it is consumed without the power supply doing anything. This current is mostly lost via the 5VSB circuit of the power supply. This value is pleasingly low in the GF2 1200W.
Average efficiency
The average efficiency is on the last place in the table, but the difference to the gold competition is not big. Furthermore, the efficiency of the power supply is even close to that of some platinum power supplies!
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 disturbing harmonics and thus also the mains load. The APFC converter does a good job here. However, it works better with 115 V than with 230 V.
