The Corsair RM850x (2024) is the objective winner of this comparison, securing more individual specification victories than its counterpart. While the Corsair AX1600i maintains a significant lead in total power capacity, offering 88% more wattage, the Corsair RM850x (2024) provides a more modern feature set. Its most impactful advantage is the inclusion of a native 12VHPWR connector, which represents a 100% improvement in connectivity support compared to the older design of the Corsair AX1600i.

Users building systems with modern graphics cards requiring the 12VHPWR standard should choose the Corsair RM850x (2024) for its superior connector compatibility. Conversely, the Corsair AX1600i remains the appropriate selection for enthusiasts or workstation users who require the massive wattage capacity that only this unit provides. By prioritizing either the specific power delivery needs of high-end hardware or the necessity for modern cable standards, buyers can select the unit that best aligns with their specific system requirements.
