The Seasonic Prime TX-1000 is the objective winner of this comparison, securing more individual specification victories than its competitor. While the Corsair AX1600i offers a significant advantage in total power capacity, providing 60% more wattage, the Seasonic Prime TX-1000 holds the most impactful edge with a 55% better MSRP. This pricing efficiency makes the Seasonic unit the superior choice for users prioritizing value while maintaining high-end performance standards across the majority of measured technical categories.

Users requiring the highest possible power output for extreme hardware configurations should select the Corsair AX1600i to leverage its superior wattage capacity. Conversely, the Seasonic Prime TX-1000 is the ideal selection for builders who want a highly competitive, cost-effective power supply that matches or exceeds the Corsair AX1600i in most other technical specifications. Choosing between them depends entirely on whether your build demands maximum raw power or a more efficient allocation of your budget.
