The Seasonic Focus GX-1000 is the objective winner of this comparison, securing more individual specification victories than its competitor. The most impactful advantage offered by the Seasonic Focus GX-1000 is its total power capacity, which provides 18% more wattage than the EVGA SuperNOVA 850 G6. While both units share identical ratings across the majority of their technical specifications, the higher power ceiling gives the Seasonic model a distinct edge in raw output capability.

Users requiring maximum power headroom for high-draw components should choose the Seasonic Focus GX-1000 to leverage its superior wattage. Conversely, the EVGA SuperNOVA 850 G6 is the better option for budget-conscious builders, as it holds a 13% advantage in MSRP. Since both power supplies are otherwise evenly matched across the remaining technical fields, the final decision rests entirely on whether your build prioritizes additional power capacity or a more favorable initial purchase cost.
