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.
