Corsair HX1000i 1000W ATX 3.0 power supply
Fully modular 1000W ATX 3.0 PSU with 80 PLUS Platinum efficiency, iCUE monitoring, zero-RPM mode and 140mm FDB fan for quiet PCIe 5.0 builds
- Clean builds with fully modular cabling
- ATX 3.0 and PCIe 5.0 compliant for modern platforms
- 140mm FDB fan gives quiet, long-lasting cooling
- iCUE software controls fan curves and OCP modes
- Zero RPM mode stops the fan at low loads
Fully Modular ATX 3.0 Power Supply
The Corsair HX1000i is a 1000W ATX 3.0 power supply built for high-end desktop systems. Its fully modular cabling lets builders connect only the cables required, simplifying cable management and improving airflow inside the case. It targets enthusiasts who need reliable power for modern components and value software monitoring. It is not suited for compact builds that require SFX form factors or lower-wattage units.
1000W Capacity With Platinum Efficiency
Rated at 1000W, the unit delivers ample headroom for multi-GPU configurations and overclocked CPUs while maintaining 80 PLUS Platinum efficiency up to 92%. The fully digital platform with resonant LLC topology and DC-to-DC conversion provides clean power and minimises coil whine. Transient spike resistance meets the ATX 3.0 standard for PCIe Gen 5 platforms. Systems with modest power demands will not utilise the full capacity.
140mm FDB Fan And iCUE Control
A 140mm fluid dynamic bearing fan enables Zero RPM mode, stopping completely at low and medium loads for near-silent operation. CORSAIR iCUE software allows custom fan curves, power monitoring, and on-the-fly switching between single and multi-rail overcurrent protection. Industrial-grade 105°C Japanese electrolytic capacitors back long-term reliability. Modern Standby support ensures fast wake times. Builders who prefer hardware-only control may find the software dependency unnecessary.

Questions sur cet article
Will the ATX 3.0 compliant 1000W unit work with my existing motherboard that uses a 24-pin and 8-pin CPU connector?
Yes, the supply is fully modular and ATX 3.0 compliant, so you can connect the 24-pin motherboard and 8-pin CPU cables from the included set to your current board.
How do I verify the 140mm FDB fan and Zero RPM mode are functioning correctly after installation?
Connect the USB link to your motherboard, open CORSAIR iCUE software, and you can monitor real-time fan speed, confirm Zero RPM activates at low load, and set custom fan curves.
Which cables come in the box and what must I purchase separately for a standard build?
The package includes a full set of fully modular cables for motherboard, CPU, and PCIe power; no extra cables are needed for a typical ATX 3.0 system.
