Corsair RM850x Shift 850W 80 Plus Gold Fully Modular Power Supply PSU (White)
ATX 3.1 Certified Power with Side-Mounted Connections & Quiet Cooling
The Corsair RM850x SHIFT 850W is a fully modular power supply designed to deliver reliable, efficient and convenient power for modern gaming and high-performance PCs. Featuring 80 PLUS Gold efficiency, an innovative side-mounted modular connection panel and ATX 3.1 certification, the RM850x SHIFT makes building and managing your system easier while providing the power modern components demand.
The innovative side-mounted modular connections move the cable interfaces to the side of the PSU, keeping them within easy reach when installing or upgrading your PC. This design makes connecting and managing cables more convenient, particularly in compatible cases. The PSU and cables are designed for ATX-format cases that are at least 210mm wide and provide side access to the power supply.
With ATX 3.1 compliance and a supplied PCIe 5.1 12V-2x6 GPU cable, the RM850x SHIFT is ready for modern graphics cards and demanding gaming systems. Its fully modular Corsair Type 5 Gen 1 Micro-Fit cables allow you to connect only the cables your system requires, helping reduce cable clutter and improve airflow inside your case.
Cooling is handled by a 140mm fluid dynamic bearing fan with Zero RPM Mode support. The fan can remain virtually silent during lower loads and automatically provides additional cooling when required. Combined with 105°C-rated Japanese primary electrolytic capacitors, the RM850x SHIFT is engineered for reliable operation and long-term durability.
