The Thermaltake Toughpower GF3 850W is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most impactful advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the EVGA SuperNOVA 850 G6. While both units share several identical specifications, the Thermaltake Toughpower GF3 850W provides superior modern connectivity options that distinguish it as the more versatile power supply unit in this head-to-head evaluation.

Users planning to build systems with modern graphics cards requiring the 12VHPWR standard should select the Thermaltake Toughpower GF3 850W for its native compatibility. Conversely, the EVGA SuperNOVA 850 G6 is the better choice for users who prioritize a higher quantity of PCIe connectors, as it offers a 200% advantage in that specific category. Choosing between these two units depends entirely on whether your hardware configuration demands the latest power delivery standard or a greater number of traditional PCIe cables.
