Overall performance tops the chart.
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).
The EVGA 850 G7 is not noisy under average loads and operating temperatures, but it will get loud if you push it hard. This affects its overall noise output.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The 850 G7 is highly efficient.
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 has good performance with 115V, while there is room for improvement with 230V input.

Thanks for the review!Reply
Glad to see a new leader. EVGA is back in it.
I think a short description of what level of system would be well served/matched to a power supply of this wattage would be a great addition to the review format.
Something along the lines of : A well performing 850 Watt PSU like this one is well suited to power a gaming system up to an i5 12600K (150 watt TDP) with an RTX 3070 Ti GPU (290 Watt). -
