Performance Rating

We have a new performance king in the 1000W Gold category! The Corsair RM1000x follows closely behind. 

Noise Rating

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).

Average noise output is low, under normal operating conditions. 

Efficiency Rating

The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.

A small efficiency boost would be desirable here, since the G6's efficiency is actually below the G3 platform's levels. 

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 PF readings are low, especially with 230V input.

    Hey there,

    Shouldn't the '1000w' in the Power specification chart be underneath the 12v rail? Also, are the amps correct? Specs from EVGA state 83.3a on the 12v rail, as opposed to 62.5?

    Why is EVGA so scared to send you a GT or GA?

    I know they're worse, but I would like to see how they relatively perform according to your specific linear testing.

    Is the Super Flower models in the comparison charts the Leadex V Pro 1000W? I think that is their only current 1000W Gold unit. It was specifically named in the review of the Corsair 2021 PSU. Will you be reviewing the Super flower Leadex V Pro?

    Compared with the 1000 G3, the G6 model with a similar capacity has a depth of 140mm and a smaller size. A 135mm fan can hardly fit its chassis. As we said before, EVGA's G6 model uses an upgraded version of the Seasonic Focus platform.

    There's no way this review looked at the fan curve for this and must have taken the average dB data from somewhere else. The low average dB is EXTREMELY misleading for this PSU. It stay quiet up to a certain power draw and then the noise SKYROCKETS from it jumping to extremely high fan speeds, but if you were to take the mean dB across its load % it would show a low average dB. Very misleading, this thing gets louder than all the fans in my case combined -- 13 Arctic fans going at 1300-1500rpm are drowned out by the volume from this PSU
