Why you can trust Tom's Hardware
The SuperNOVA 850 G6 is a fine PSU and uses a better platform than the G5 models. Nonetheless, it didn't manage to impress us as much as the 1000 G6 did. Don't get us wrong, the overall performance is good, but the competition in the 850W category is fierce with many great offerings. The changes that EVGA made to the Seasonic Focus platform led to higher efficiency at light loads and rock-steady protection features, but this wasn't enough to achieve the same performance levels as the 850 G3, which is among the best PSUs in the wattage category. We would also like to see lower inrush currents with 230V.
Thanks to its cooperation with Seasonic, EVGA is back in the big boys club in the PSU market. The new G6 line is a good successor to the legendary G2 models, although the 850 G6 unit doesn't achieve the same high-performance levels as the 850 G3. Nonetheless, it stays close to the competition, and under normal temperatures, the operating noise is low. Notable alternatives to the EVGA SuperNOVA 850 G6 are the Corsair RM850x (2021), the Seasonic GX-850, the XPG Core Reactor 850, and the Cooler Master V850 Gold V2.

Johnpombrio I own 3 of the EVGA Supernova 850 G2 power supplies with LOTS AND LOTS of extra modular cables 😊. I didn't know that they were legendary, heh. The specs on the side of the PSU are the same as the G6 so I expect that the main difference is the efficiency. I turned on ECO mode and I doubt the fan ever spins.Reply -
taz-nz The biggest improvement is they got rid of the green chrome fan grill from the G5 series.Reply
If it's as reliable as the G2, G3 and G5 series, I look forward to building a lot of PCs with them.
It would be nice if they stepped up their game in cheaper non-modular models, they are significantly lower quality. -
SteelTeel Why is your noise measurement so different from what EVGA posts on its website? Are these measurements carried out with ECO mode enabled?Reply
