The Seasonic VERTEX GX-1000 is the objective winner of this comparison, securing more category victories than its competitor. Its most impactful advantage is the inclusion of the 12VHPWR connector, which represents a 100% improvement over the EVGA SuperNOVA 850 G6. While the EVGA SuperNOVA 850 G6 maintains a 32% advantage in MSRP, the Seasonic VERTEX GX-1000 provides superior hardware compatibility for modern systems requiring the latest power delivery standards.

Users prioritizing the latest connectivity standards for high-end graphics cards should choose the Seasonic VERTEX GX-1000 for its native 12VHPWR support. Conversely, the EVGA SuperNOVA 850 G6 is the better option for budget-conscious builders who do not require the newest connector type and prefer a lower MSRP. Selecting between these two power supplies depends entirely on whether your build necessitates modern power delivery or if cost efficiency is your primary concern.
