The Corsair AX1600i is the objective winner of this comparison, securing a lead across four of the nine evaluated specifications. Its most significant advantage is the inclusion of PCIe connectors, which offer a 100% improvement over the alternative. This superior connectivity provides a distinct hardware edge for systems requiring extensive power distribution to multiple expansion cards or high-end components, establishing this unit as the more robust option for demanding configurations based on the provided technical data.

Users should select the Corsair AX1600i if their primary requirement is maximizing PCIe connectivity for complex builds. Conversely, the Corsair RM1000x (2024) is the better choice for those prioritizing modern standards, as it holds a 100% advantage regarding the 12VHPWR connector. Choosing between these two power supplies depends entirely on whether your specific system architecture relies more heavily on traditional PCIe power delivery or the newer 12VHPWR interface for current hardware compatibility.
