The DeepCool PX850G is the objective winner of this comparison, securing three spec victories against the Corsair RM850x, which recorded zero. The most impactful advantage offered by the DeepCool PX850G is the inclusion of a 12VHPWR connector, representing a 100% improvement over the alternative. This specific hardware addition provides a significant functional edge for modern system builds that require this native power standard, whereas the Corsair RM850x lacks this specific connectivity feature entirely.

Users planning to build a system with modern graphics cards that utilize the 12VHPWR standard should choose the DeepCool PX850G to ensure native compatibility and streamlined power delivery. Conversely, the Corsair RM850x remains a viable option for those whose hardware configurations do not require this specific connector. By evaluating your current or future GPU requirements against these connectivity differences, you can determine which unit aligns best with your specific power delivery needs.
