The SuperNOVA 1000 G6 is an impressive unit by EVGA, which doesn't just take the Seasonic Focus platform and rebadge it, but actually makes some noticeable upgrades to improve performance and bring it up to today's standards. The newly released Corsair RM1000x is a tough opponent, but the 1000 G6 manages to take a slight lead in overall performance while keeping average noise output about one decibel lower. When it comes to efficiency, the G6 unit performs very well at light loads, but the average efficiency doesn't reach the levels of the previous G3 platform, which Super Flower provided. Another important region where the G6 model cannot take the lead from the competition is transient response. Not that it doesn't have a satisfactory transient response, but the competition performs better in this regard.

It is nice to see EVGA back on track in the PSU market. After Super Flower and FSP, it's Seasonic's turn to provide a platform, and the result is very good. The SuperNOVA (what a name for a PSU!) 1000 G6 is among the best products money can buy in this market segment, and its main competitor is the Corsair RM1000x which offers similar performance levels and has about the same average noise output, so it is up to you which one you prefer. A notable difference between these PSUs is that the G6 has two more PCIe connectors, while the Corsair unit is among the few that come with three EPS connectors.

    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
