The overall performance cannot meet the competition. The difference is not huge, though, but the second from the bottom place still doesn't look good.
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
Under normal operating temperatures, the average noise output is low and this is a major asset for the PQ850M
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The average efficiency score is decent. It would be nice to be closer to or above 89%.
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 needs tuning for higher PF readings.
