The Corsair RM850x (2024) is the objective winner of this comparison, securing more spec victories than its competitor. Its most significant advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the alternative. This feature ensures superior compatibility with modern hardware requirements, making it the more robust choice for users prioritizing current connectivity standards and higher power capacity in their system builds.

Users should select the Corsair RM850x (2024) if they require the 12VHPWR connector for modern graphics cards and prefer the higher power ceiling.
