The CORSAIR RM850e is an 850W power supply unit engineered for modern PC builds that require stable and efficient power delivery. It is fully compliant with the latest ATX 3.1 and PCIe 5.1 standards, ensuring broad compatibility with current-generation components. The unit holds an 80 PLUS Gold certification, signifying up to 90% operational efficiency which helps to reduce heat output and energy consumption. A native 12V-2x6 GPU power cable is included to directly support high-performance graphics cards without the need for additional adapters.
This PSU utilizes a fully modular cabling system, which allows builders to use only the necessary cables for their specific hardware configuration. This approach simplifies the installation process and can improve airflow within the case. Its compact 140mm-deep chassis fits a wide range of ATX-compatible enclosures, providing flexibility for system integrators. For acoustic performance, the RM850e is equipped with a 120mm fan that features a zero RPM mode, stopping fan rotation entirely under low to medium loads to minimize noise.
