Corsair has updated its AX1600i, the company's highest-output consumer power supply, with pin monitoring, new GPU power connectors, and a smaller chassis.
The original AX1600i was already unusual for a PSU: it shipped with digital monitoring capabilities most power supplies skip entirely. The refresh goes further. Pin monitoring now tracks whether connectors are properly seated, a feature that carries real weight given the broader industry's recent history with high-power GPU connector reliability. Corsair has also replaced the GPU power sockets with what it calls "proper" ones, implying the previous design had room for improvement, and shaved down the physical size of the unit, which matters when you are fitting 1,600 watts of capacity into a case that was not designed around it.
The connector work is the part worth paying attention to. Pin monitoring that can flag a loose connection before it causes damage is a legitimate engineering addition, not a spec-sheet checkbox. Builders running power-hungry single-GPU configurations have concrete reasons to care about sound power delivery, and a warning system built into the PSU itself beats finding out the hard way.
The price has not been announced. For a flagship Corsair unit with digital monitoring and 1,600W output, that number is going to land somewhere uncomfortable.
