The Corsair RM850x (2024) is the objective winner of this comparison, securing more total spec victories than its competitor.

This feature ensures superior compatibility with modern hardware requirements, positioning the unit as the more versatile choice for users prioritizing current connectivity standards and higher power delivery capabilities in their system builds.

Users should choose the Corsair RM850x (2024) if they require the 12VHPWR connector for modern graphics cards and need the higher power capacity.
