Power supply unit CORSAIR HX1000i 1000 W, 24-pin ATX, 80 PLUS Platinum, 140 mm fan, ATX black

CORSAIR HX1000i is a 1000 W ATX power supply designed for high-performance desktops and workstations. It delivers up to 1000 W of continuous power through standard ATX connections and is certified 80 PLUS Platinum for high energy efficiency across a wide input range (100–240 V AC, 47–63 Hz). The unit uses a compact ATX form factor (180×150×86 mm), a 24‑pin ATX motherboard connector and fully modular, side-mounted cabling to simplify installations and upgrades. Integrated iCUE LINK technology and a built-in iCUE LINK System Hub allow centralized control and automatic detection of compatible cooling and lighting components, while a 140 mm fluid dynamic bearing fan with Zero RPM mode provides quiet operation at lower loads.

Advantages

The HX1000i combines high efficiency with stable power delivery and advanced connectivity. 80 PLUS Platinum certification reduces wasted energy and heat, while the fully digital power design improves voltage regulation and transient response. Side-mounted modular connectors and a debossed PVC cable kit with smaller Type-5 connectors improve cable routing and case compatibility. Native 12V-2x6 GPU power support and ATX 3.1 / PCIe 5.1 readiness ensure compatibility with modern high-power graphics cards and CPU platforms. Integrated iCUE LINK System Hub provides system-level control for up to 24 iCUE LINK devices.

How to use

Install the CORSAIR HX1000i into a compatible ATX case and secure it using the standard mounting points. Connect the 24‑pin ATX cable to the motherboard and attach the required modular cables to the CPU, GPU and storage devices using the side-mounted connectors. Connect the power cord to a suitable AC source within the specified 100–240 V range. For devices compatible with iCUE LINK, route and attach iCUE LINK cables to the integrated System Hub and use CORSAIR iCUE software to detect and configure connected components. Ensure proper airflow inside the case and verify that the fan operates as expected; Zero RPM mode will keep the fan stopped at low-to-medium loads.

Recommendations

Use this unit with systems that require high, stable power delivery and modern connectivity. Keep airflow unobstructed around the 140 mm fan, use the modular cabling to minimize cable clutter, and update CORSAIR iCUE software and firmware to maintain compatibility with the iCUE LINK ecosystem and to access monitoring and OCP adjustment features.
