The Corsair AX1600i is the objective winner of this comparison, securing victory across five of the nine evaluated specifications. Its most significant advantage is the inclusion of PCIe connectors, which provide a 233% increase in capacity compared to the alternative. This superior connectivity establishes the unit as the more robust option for systems requiring extensive hardware support, effectively outperforming the Corsair RM750e in the majority of technical categories measured during this assessment.

Users building high-end workstations or systems with multiple graphics cards should select the Corsair AX1600i to leverage its superior PCIe connector count. Conversely, those prioritizing modern hardware compatibility should choose the Corsair RM750e, as it offers a 100% advantage regarding the 12VHPWR connector. Selecting between these two units depends entirely on whether your specific build requires the extensive PCIe capacity of the former or the native 12VHPWR support provided by the latter.
