The Corsair AX1600i is the objective winner of this comparison, securing victories in six out of nine evaluated specifications. Its most significant technical advantage is the inclusion of PCIe connectors, which offer a 400% improvement over the alternative. This superior connectivity ensures that the unit can support more demanding hardware configurations compared to the EVGA 500 BQ, which only outperformed its competitor in a single category.

Users requiring extensive hardware support and high-end connectivity should choose the Corsair AX1600i for its clear lead in technical specifications. Conversely, the EVGA 500 BQ is the appropriate selection for budget-conscious buyers, as it holds a 93% advantage in MSRP. Selecting between these two units depends entirely on whether your priority is maximizing the number of available PCIe connections or minimizing the initial purchase cost.
