The EVGA SuperNOVA 850 G6 is the objective winner of this comparison, securing more individual specification victories than its competitor. While both units share several identical characteristics, the most impactful advantage for the EVGA SuperNOVA 850 G6 is its superior quantity of PCIe connectors, which represents a 100% improvement over the Corsair RM750x (2024). This increased connectivity provides a significant edge for systems requiring multiple high-power graphics cards or complex peripheral configurations.

Users who prioritize maximum PCIe connectivity for multi-GPU setups or extensive hardware expansion should choose the EVGA SuperNOVA 850 G6. Conversely, the Corsair RM750x (2024) is the better selection for builders utilizing modern hardware that requires the 12VHPWR connector, as it offers a 100% advantage in this specific interface category. Selecting between these two power supplies depends entirely on whether your build demands more traditional PCIe cables or the newer 12VHPWR standard.
