The EVGA SuperNOVA 1000 G6 is the objective winner of this comparison, securing more wins across the evaluated specifications. Its most significant advantage over the alternative is the inclusion of SATA connectors, which provides a 33% increase in capacity for peripheral connectivity. While both units share several identical technical specifications, the higher power ceiling and expanded connector count make the EVGA SuperNOVA 1000 G6 the more robust option for systems requiring extensive hardware support.

Users building high-end workstations or systems with numerous storage drives should choose the EVGA SuperNOVA 1000 G6 to leverage its superior SATA connectivity. Conversely, the EVGA SuperNOVA 850 G6 is the better choice for budget-conscious builders who do not require the extra connectors, as it offers a 24% advantage in MSRP. Selecting between these two power supplies depends entirely on whether your specific build necessitates the additional peripheral support or favors the lower cost.
