Product overview
Announced January 8, 2018 at CES, the Corsair AX1600i is the AXi-series digital flagship and successor to the AX1500i. It combines a 1600 W ATX design with 80 PLUS Titanium efficiency and a GaN totem‑pole PFC stage, with iCUE software monitoring/control.Sourcecorsair.com
Positioned as a flagship PSU, it exists to power extreme desktops where multiple high-end GPUs/CPUs, many peripherals, and overclocking demand very high, fully modular capacity with a 10‑year warranty. It conforms to ATX12V v2.4 (no native ATX 3.x/12VHPWR), but supports Corsair’s Type‑4 12VHPWR cable for modern ATX 3.0 GPUs. Not discontinued as of 2026.Sourcecorsair.com
