The Corsair SF850 and the EVGA SuperNOVA 850 G6 represent a tie in this objective comparison, as both units secured an equal number of specification wins. The most impactful advantage for the Corsair SF850 is the inclusion of a 12VHPWR connector, which provides a 100% improvement in compatibility for modern hardware. Conversely, the EVGA SuperNOVA 850 G6 holds a 100% advantage in the total number of PCIe connectors available for peripheral expansion.

Users planning to build a system with modern graphics cards requiring a 12VHPWR connection should prioritize the Corsair SF850 for its native support. Alternatively, those who require a higher quantity of traditional PCIe connectors for multiple expansion cards or complex power configurations should select the EVGA SuperNOVA 850 G6. Both power supplies offer equivalent performance across the remaining measured specifications, making the choice dependent entirely on your specific connectivity requirements.
