The Thermaltake Toughpower GF3 850W is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most significant advantage over the competition is the inclusion of a 12VHPWR connector, which represents a 100% improvement in that specific connectivity metric. While the EVGA SuperNOVA 1000 G6 offers a 300% advantage in the number of available PCIe connectors, the overall spec-based victory belongs to the Thermaltake unit for its superior feature set.

Users should choose the Thermaltake Toughpower GF3 850W if they require the modern 12VHPWR connector for current hardware compatibility. Conversely, the EVGA SuperNOVA 1000 G6 is the better selection for builders who prioritize a higher quantity of PCIe connectors for their specific power delivery needs. Selecting between these two power supplies depends entirely on whether your build configuration demands more traditional PCIe cables or the newer 12VHPWR standard for your graphics card.
