The Thermaltake Toughpower GF3 1200W is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most impactful advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the alternative. While the EVGA SuperNOVA 1000 G6 holds its own with a 60% advantage in the number of available PCIe connectors, the overall specification count favors the Thermaltake unit as the more versatile power supply option.

Users should choose the Thermaltake Toughpower GF3 1200W if they require native 12VHPWR connectivity for modern hardware configurations. Conversely, the EVGA SuperNOVA 1000 G6 is the better selection for builders who prioritize a higher quantity of traditional PCIe connectors for their specific component setup. Selecting between these two units depends entirely on whether your system build relies on the newer 12VHPWR standard or a greater density of standard PCIe power cables.
