The Seasonic Prime TX-1600 ATX 3.1 is the objective winner of this comparison, securing five out of seven total specification victories. Its most impactful advantage over the EVGA SuperNOVA 850 G6 is the inclusion of a 12VHPWR connector, which represents a 100% improvement in that specific connectivity category. While the EVGA SuperNOVA 850 G6 remains competitive in its own right, the Seasonic Prime TX-1600 ATX 3.1 demonstrates superior technical specifications across the majority of the evaluated fields.

Users prioritizing modern connectivity and high-capacity power delivery should choose the Seasonic Prime TX-1600 ATX 3.1 for its native 12VHPWR support.
