The Seasonic VERTEX GX-1000 is the objective winner of this comparison, securing more victories across the evaluated specifications. Its most significant advantage is the inclusion of double the number of SATA connectors compared to the EVGA SuperNOVA 850 G6, representing a 100% improvement in that category. While the EVGA SuperNOVA 850 G6 holds its own with a 50% advantage in PCIe connectors, the Seasonic VERTEX GX-1000 ultimately leads in the majority of the measured technical fields.

Users who prioritize extensive storage configurations or require a high volume of peripheral connections should choose the Seasonic VERTEX GX-1000 to leverage its superior SATA capacity. Conversely, the EVGA SuperNOVA 850 G6 is the better selection for builders whose primary requirement is a higher density of PCIe connectors for their specific hardware setup. Selecting between these two power supplies depends entirely on whether your build demands more SATA connectivity or a greater number of PCIe power cables.
