Product Description
Corsair RM1000x – Silent, Powerful, and Built to Last
Quiet, Efficient, and Ready for Next-Gen Power
The Corsair RM1000x is a reliable, low-noise power supply engineered for efficiency and clean cable management. Its fully modular design lets you connect only the cables your system requires, reducing clutter and improving airflow. Cybenetics Gold-certified for up to 91% efficiency, it ensures lower power consumption, reduced heat output, and quieter operation. Built to meet the latest ATX 3.1 standard, it supports PCIe 5.1 and is designed to handle transient power spikes with ease—making it ideal for modern, high-performance systems.
Optimized for GPUs
The RMx Series is designed for seamless compatibility and clean aesthetics. A native 12V-2×6 connector offers direct, adapter-free power delivery to the latest GPUs. Ultra-flexible embossed cables with low-profile combs provide a sleek, professional look while simplifying installation. For quiet performance, a 140mm fluid dynamic bearing (FDB) fan operates with a finely tuned curve, keeping noise to a minimum—even under full load. Plus, a convenient rear fan speed adjustment knob gives you manual control when you need it.
Unmatched Reliability and Silent Operation
Built with 100% Japanese electrolytic capacitors, this PSU ensures consistent, reliable power with excellent electrical performance, even under high temperatures—thanks to capacitors rated for up to 105°C. Designed to operate in high-stress environments, it boasts a 50°C maximum operating temperature for sustained reliability. For near-silent performance, the Zero RPM fan mode kicks in at lower loads, keeping noise to an absolute minimum. Backed by a ten-year warranty, this power supply is built to last through multiple system builds, offering peace of mind for years to come.
