The Corsair RM850x (2024) is the objective winner of this comparison, securing more category victories than its predecessor. Its most significant advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the original model. While the Corsair RM850x maintains a 7% lead in MSRP, the newer iteration provides superior hardware compatibility for modern systems that require this specific power interface for high-end graphics cards.

Users building a modern PC with a GPU requiring a 12VHPWR connector should choose the Corsair RM850x (2024) to ensure native compatibility and avoid the need for adapters. Conversely, the original Corsair RM850x remains a viable option for budget-conscious builders who do not require this specific connector and prefer to take advantage of the 7% lower MSRP. Select the model that best aligns with your current hardware requirements and overall build budget.
