The Seasonic Prime TX-1000 is the objective winner of this comparison, securing five category wins against the single victory held by the EVGA SuperNOVA 850 G6. The most impactful advantage for the Seasonic Prime TX-1000 is its superior connectivity, offering 56% more SATA connectors than its competitor. Conversely, the EVGA SuperNOVA 850 G6 holds a significant 50% advantage in MSRP, making it the more cost-effective option for users prioritizing initial purchase savings over expanded hardware support.

Users should choose the Seasonic Prime TX-1000 if they require extensive storage expansion or complex peripheral setups that benefit from the increased SATA connector count. The EVGA SuperNOVA 850 G6 is the better choice for budget-conscious builders who do not need the additional connectivity provided by the Seasonic unit. Selecting between these two power supplies depends entirely on whether your build prioritizes a lower MSRP or the maximum number of available SATA connections.
