CORSAIR Power Supply - 750w Rm750x 24-pin ATX Black

Power your next build with the CORSAIR RMx Series fully modular PSU, offering quiet operation and Cybenetics Gold-certified efficiency. The RMx Series is an ATX 3.1–compliant power supply designed to deliver stable power to modern high-performance PCs, featuring all-Japanese 105°C-rated capacitors and support for current GPU power connectors.

Advantages

This fully modular PSU combines low acoustic profile operation with high reliability. It operates continuously at up to 50°C, uses industrial-grade 105°C Japanese electrolytic capacitors for long-term stability, and meets ATX 3.1 requirements to support contemporary sleep/hibernate states and modern CPU/GPU power demands. Fully modular connectors and an included native 12V-2x6 GPU cable simplify installation and cable management.

How to use

Install the PSU in a compatible ATX case following standard safety precautions and manufacturer instructions. Connect only the modular cables you need to motherboard, CPU, storage and GPU using the provided connectors and the native 12V-2x6 GPU cable for supported graphics cards. Use the manual fan override knob to increase fan speed when additional airflow or exhaust is required; otherwise, Zero RPM mode keeps noise at a minimum under low to medium loads.

Recommendations

For reliable operation, ensure your system cooling and case ventilation are adequate when running under sustained high loads or elevated ambient temperatures. Verify connector compatibility with your GPU and components before installation.
