Overall efficiency is high, taking the lead from competing offerings. With 87% overall efficiency, this PSU is borderline Gold in Cybenetics. 

Power Factor Rating

The following graphs show the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius and 115V/230V voltage input. 

The APFC converter could be tuned better for 230V input.
