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.
