The Seasonic Prime TX-1600 ATX 3.1 is the objective winner of this comparison, securing five out of seven spec victories. Its most impactful advantage is the inclusion of the 12VHPWR connector, which represents a 100% improvement over the alternative. While the EVGA SuperNOVA 850 G6 manages to win one category, it falls behind in the majority of technical specifications evaluated, despite offering a 74% better MSRP that serves as its primary advantage.

Users prioritizing modern connectivity and high-capacity power delivery should select the Seasonic Prime TX-1600 ATX 3.1 for its superior hardware standards. Conversely, the EVGA SuperNOVA 850 G6 is the logical choice for budget-conscious builders who do not require the advanced connector features found in the higher-tier model. Choosing between these two units depends entirely on whether your build requires the latest power standards or if you prefer to prioritize the significant cost savings provided by the lower-priced option.
