The DeepCool PX850G is the objective winner of this comparison, securing more individual specification victories than the Corsair RM850x. While both units share several identical performance metrics, the most impactful advantage for the DeepCool PX850G is its 12VHPWR connector, which offers a 100% improvement over the alternative. This specific connectivity feature provides a significant edge for modern hardware compatibility, allowing the unit to outperform its competitor across the majority of evaluated technical categories.

Users prioritizing modern GPU connectivity should select the DeepCool PX850G to take advantage of its superior 12VHPWR support. Conversely, the Corsair RM850x remains the better choice for builders who require a high volume of peripheral connections, as it provides 150% more SATA connectors than the DeepCool model. Choosing between these two power supplies depends entirely on whether your specific build configuration relies more heavily on legacy storage expansion or the latest high-power graphics card standards.
