The DeepCool PX850G is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most impactful advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement over the alternative. This feature provides essential native compatibility for modern hardware requirements that the competing unit lacks. While the competition remains strong in other areas, the superior connectivity of the DeepCool PX850G makes it the more versatile choice for current system builds.

Users prioritizing modern hardware compatibility should choose the DeepCool PX850G to utilize its native 12VHPWR connector. Conversely, those who prioritize power conversion should select the Fractal Design Ion+ 2 Platinum 860W, which offers a 25% advantage in efficiency. By focusing on these specific strengths, builders can align their power supply selection with either the need for advanced connector standards or the desire for higher operational efficiency in their desktop configuration.
