Key Specifications

Three EPS12V Connectors for Future-Proof Builds

The HX1000i features three EPS12V connectors, providing the headroom needed for extreme multi-GPU setups and high-core-count processors. Combined with fully modular cabling, you can configure exactly the connections you need without excess clutter, making it ideal for both current high-end systems and future upgrades.

ATX 3.0 Certified for Modern Components

Meeting the ATX 3.0 standard, this PSU delivers reliable power delivery for today’s most demanding hardware. The included PCIe 5.0 12VHPWR cable supports modern graphics cards like NVIDIA GeForce RTX 40 Series, ensuring compatibility with the latest gaming and content creation hardware that requires stable, high-current power delivery.

140mm FDB Fan with Zero RPM Mode

The fluid dynamic bearing fan operates silently under typical loads thanks to Zero RPM mode, which keeps the fan off during low and medium power draw. When cooling is needed, the 140mm fan spins only as fast as necessary, balancing quiet operation with effective thermal management for your components.

105°C-Rated Japanese Capacitors

Built with 100% industrial-grade, 105°C-rated Japanese electrolytic capacitors, the HX1000i ensures unwavering power delivery and long-term reliability. These premium components maintain stable voltage output even under heavy loads, protecting your valuable hardware from power fluctuations and extending the lifespan of both the PSU and connected components.

iCUE Software Integration

Monitor real-time power consumption, adjust fan curves, and toggle between single-rail and multi-rail operation using CORSAIR iCUE software. This level of control lets you optimise performance for your specific workload, whether you’re gaming, rendering, or running intensive applications that demand consistent power delivery.
