The MSI MPG A750G PCIE5 is the objective winner of this comparison, securing more individual specification victories than its competitor. While the Corsair AX1600i offers a significant advantage in power capacity, boasting 113% more wattage, the MSI MPG A750G PCIE5 provides a more modern feature set. Its most impactful advantage is the inclusion of a 12VHPWR connector, which represents a 100% improvement in native compatibility for current hardware standards compared to the alternative.

Users building a modern system that requires the latest power delivery standards should choose the MSI MPG A750G PCIE5 for its native connector support. Conversely, the Corsair AX1600i is the superior choice for enthusiasts or professionals who require extreme power output for high-draw components. Selecting between these two units depends entirely on whether your priority is the specialized connectivity of the MSI unit or the massive raw wattage capacity provided by the Corsair model.
