Corsair HX1200i 1200W Fully Modular ATX Power Supply

The Corsair HX1200i delivers 1200W of 80 PLUS Platinum certified power with up to 92% efficiency, ensuring exceptional performance for high-end gaming PCs and workstations. This fully modular power supply features ATX 3.1 and PCIe 5.1 compliance, making it ready for the latest GPU and CPU configurations including PCIe Gen 5 graphics cards.

Advanced Cooling and Quiet Operation

Equipped with a 140mm fluid dynamic bearing (FDB) fan, the HX1200i provides long-lasting, ultra-quiet cooling performance. Zero RPM fan mode ensures near-silent operation during low to medium loads, with the fan only spinning up when necessary. The digitally controlled platform with resonant LLC topology minimizes coil whine and electrical noise for whisper-quiet operation even under heavy loads.

Comprehensive Connectivity

The HX1200i includes extensive fully modular cabling: 1x ATX 24-pin, 2x EPS/ATX12V 8-pin (4+4), 5x PCIe 8-pin (6+2), 2x 12V-2x6 PCIe 16-pin connectors for next-generation graphics cards, 8x SATA, 6x PATA (4-pin), and 1x USB Type-C to 10-pin connector. Connect only the cables your system requires for improved airflow and cable management.

iCUE Software Integration

Full integration with Corsair iCUE software enables advanced customization and monitoring. Create custom fan curves, monitor real-time power consumption, voltage levels, and system efficiency. Toggle between single and multi-rail overcurrent protection (OCP) modes on-the-fly to match your system requirements.

Premium Components and Reliability

Built with 100% industrial-grade, 105°C rated Japanese electrolytic capacitors for unwavering power delivery and long-term reliability. The digital platform ensures clean, consistent power across all rails. Modern Standby sleep mode support provides extremely fast wake-from-sleep times and improved low-load efficiency. Backed by a comprehensive 10-year warranty.

ATX 3.1 and PCIe 5.1 Ready

Full compliance with Intel's ATX 3.1 power standard ensures compatibility with the latest PCIe Gen 5 platforms and resistance to transient power spikes up to 200% of rated power. The included 12V-2x6 PCIe connectors deliver stable power to the most demanding next-generation graphics cards.
