The Corsair RMx Series RM850x is a fully modular 850W ATX power supply built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC with virtually silent operation—available in multiple generations (2018, 2021, and 2024 ATX 3.1 models) all providing reliable performance. The latest 2024 model (CP-9020270) is ATX 3.1 compliant supporting PCIe 5.1 with a native 12V-2x6 (12+2-pin) connector capable of delivering 600W for modern graphics cards such as NVIDIA RTX 40-series, with support for 2x transient power excursions up to 200% of max power resisting power spikes from next-gen GPUs, while older models use ATX12V v2.4 and EPS12V 2.92 standards with traditional PCIe 6+2-pin connectors. 80 PLUS Gold certification delivers up to 90% efficiency at real-world loads, reducing power consumption from the wall, generating less heat, and lowering electricity costs over time. Cybenetics Gold efficiency rating (87-89% at 115V, 89-91% at 230V) and Cybenetics A- noise rating (25-30 dBA average) ensure efficient, quiet operation perfect for noise-sensitive environments. Built with 100% industrial-grade, 105°C-rated Japanese electrolytic capacitors for unwavering power and reliability, the RM850x ensures reliable power for your PC even under high-stress conditions with long-term stability. The ultra-quiet 135mm rifle-bearing fan (2018 model) or 140mm magnetic levitation bearing fan (2021\/2024 models) with Zero RPM Fan Mode allows the fan to remain off at low to medium loads for virtually silent operation—the fan doesn't spin at all during idle and light workloads, providing near-silent computing, then intelligently ramps up only when needed with precise thermally controlled speed for optimal cooling and minimal noise. Fully modular Type 4 low-profile, all-black cables (sleeved and flat mix) allow you to connect only the cables your system needs, dramatically reducing cable clutter inside your case and promoting better airflow for improved cooling while delivering clean aesthetics. The 2021 model features three EPS connectors—something hard to find in today's market even in stronger PSUs—perfect for supporting ultra-high-end mainboards requiring multiple CPU power cables. Rated for continuous full power delivery at 47°C (2021 model) or 50°C ambient temperature, the RM850x delivers dependable performance even in thermally challenging environments. The compact 160mm length (standard models) or 180mm (white variant) ensures easy installation in standard ATX cases without compatibility issues. Fully compliant with ATX v2.52 (2021 model) or ATX 3.1 (2024 model), the RM850x provides high overall performance with quiet operation making it ideal for delivering dependable power to today's top-performing PCs. Multi-GPU ready for both SLI and CrossFire configurations. Comprehensive protection circuitry guards against over voltage, under voltage, over current, over power, short circuits, and over temperature conditions, protecting both the PSU and your valuable components. With a robust 100,000-hour MTBF (Mean Time Between Failures) rating and backed by CORSAIR's industry-leading 10-year warranty with world-class support—a must in this price range matching all competing offerings—the RM850x delivers peace of mind and reliable performance for a decade through multiple builds.
