The CORSAIR RM850x SHIFT is an 850W power supply unit designed for ATX systems, featuring an 80 PLUS Gold certification for efficiency. It complies with the ATX 3.1 standard and is PCIe 5.1 ready, providing stable power delivery for contemporary high-performance components. A native 12V-2x6 cable is included for direct connection to modern graphics cards, eliminating the need for adapters. Its fully modular cabling system allows for the use of only required cables, which can contribute to cleaner builds and improved internal airflow.
A defining characteristic of this PSU is its side-mounted connector panel, which repositions the modular interface for more direct cable routing and access in compatible chassis. For thermal management, it incorporates a 140mm fluid dynamic bearing fan that operates silently under low and medium loads via a Zero RPM mode. The unit is constructed with 100% Japanese capacitors rated for 105°C to support consistent performance. A full suite of electrical protections is integrated to safeguard connected hardware from power anomalies.
