01 / 06Corsair HX1000i 1000W 80 Plus Platinum Fully Modular ATX Power Supply
The Corsair HX1000i 1000W 80 Plus Platinum Fully Modular ATX Power Supply combines ATX 3.0 and PCIe 5.0 compliance with Platinum-grade efficiency for the most power-demanding builds. A 140mm fluid dynamic bearing fan runs in zero-RPM mode at low to medium loads for near-silent operation, while CORSAIR iCUE software enables custom fan curves, real-time power monitoring, and on-the-fly switching between single and multi-rail OCP protection. Designed for high-end Intel Core Ultra and AMD Ryzen 9000 platforms paired with RTX 5090 / Radeon RX 9070 XT class graphics cards.
Features
- 80 PLUS Platinum Efficiency — Operates at up to 92% efficiency, reducing heat output and electricity usage compared to Gold-rated units under equivalent workloads.
- ATX 3.0 & PCIe 5.0 Compliant — Natively supports the 16-pin power connector for RTX 50 series and Radeon RX 9000 series GPUs, handling transient power spikes per the ATX 3.0 specification.
- 140mm Fluid Dynamic Bearing Fan — Larger fan diameter combined with FDB technology delivers extremely quiet airflow; zero-RPM mode disables the fan entirely at low to medium loads.
- CORSAIR iCUE Software Integration — Custom fan curves, live power rail monitoring, and switchable single/multi-rail OCP are all managed through iCUE without any hardware changes.
- Fully Modular Harness — All cables are removable, including the ATX and EPS connectors, for a completely clean build interior.
- 7-Year Warranty — Corsair's full warranty programme applies to every HX1000i unit.
