Digital ATX Power Supply

The Corsair AX1600i CP-9020087-NA is a 1600 W ATX power supply built with gallium nitride transistors and 100% 105°C Japanese capacitors. It targets builders of high-end workstations or multi-GPU systems who need continuous, ultra-stable delivery at 80 PLUS Titanium efficiency.

Fully Modular Cable Set

Full modularity lets you attach only the cables your build requires, reducing clutter and improving airflow. The bundle includes 10 PCIe 6+2-pin connectors, 16 SATA power connectors, two EPS 4+4-pin cables, and a USB link for software monitoring.

Single +12V Rail Design

All 1600 W are provided on a single +12V rail, simplifying load balancing across multiple graphics cards and storage arrays. The 140 mm FDB fan operates at low noise while maintaining thermal headroom for sustained output.

Questions about this item

Will the 140 mm FDB fan need replacement after years of continuous use?

The 140 mm fluid-dynamic-bearing fan is rated for long life; under normal loads it should run for years without service, and the unit carries a multi-year manufacturer warranty.

What thermal limit appears first when the AX1600i runs at full 1600 W for hours?

Internal 105 °C Japanese capacitors set the thermal ceiling; the digital controller will throttle or shut down before those caps exceed their rated temperature.

How loud and how hot does the 140 mm fan get during all-day 1600 W operation?

At high load the fan spins faster but stays within spec; the 80 PLUS Titanium efficiency above 94 % keeps waste heat low, so case airflow typically handles the exhaust.
