HX1000i 1000 W ATX power supply

The Corsair HX1000i is a fully modular ATX12V 2.4 unit rated for 1000 W continuous output. It targets enthusiast builders who want platinum-grade efficiency and a single +12 V rail for high-end graphics cards and multi-CPU workstations.

Full modular installation and cable routing

Fully modular cabling lets you connect only the leads your build requires, reducing clutter inside the case. Three dedicated 4+4-pin CPU cables and three PCIe 6+2-pin cables are included, so most modern motherboards and dual-GPU setups are covered without adapters. The 140 mm fluid-dynamic-bearing fan runs quietly and meets Cybenetics A noise certification.

Capacity headroom for demanding systems

The single +12 V rail delivers the full 1000 W to graphics cards and processors, while minor rails provide 25 A each on +3.3 V and +5 V. Eight SATA and eight PATA connectors give plenty of drive power. At loads approaching the 1000 W limit the fan ramps up to maintain thermal margins.

Questions about this item

How can I verify the Corsair HX1000i is operating correctly after installation?

Connect the included USB Type-C to 10-pin cable to the motherboard, then run the Corsair Link software to monitor the 1000 W output, fan speed, and efficiency in real time.

What cables come in the box and what must I purchase separately for a typical build?

The box supplies one 24-pin ATX cable, three 4+4-pin CPU cables, three dual 6+2-pin PCIe cables, two SATA chains, two PATA chains, and the USB link cable; no extra cables are required for standard ATX builds.

Which capacity should I choose if my system draws up to 1000 W from a single +12 V rail?

This model provides a single +12 V rail rated for the full 1000 W, so it covers the entire load without needing a higher-capacity unit.
