The Seasonic Prime TX-850 is the objective winner of this comparison, securing more individual specification victories than its competitor. While both power supplies share five identical specifications, the Seasonic Prime TX-850 holds a significant lead in connectivity options. Its most impactful advantage is the inclusion of SATA connectors, which provides a 56% increase in capacity compared to the EVGA SuperNOVA 850 G6, making it the superior choice for systems requiring extensive peripheral support.

Users who prioritize budget efficiency should select the EVGA SuperNOVA 850 G6, as it offers a 35% advantage in MSRP. This unit is ideal for builders who do not require the high volume of SATA connections found in the alternative. Conversely, those managing complex storage arrays or systems with numerous peripherals will benefit from the Seasonic Prime TX-850, as its superior connector count ensures better hardware compatibility for data-heavy configurations.
