CORSAIR RM850e 850W 80 PLUS Gold Fully Modular Power Supply – Black | RM850e
The CORSAIR RM850e is a compact, fully modular 850W power supply featuring 80 PLUS Gold efficiency, Intel ATX 3.1 certification, and PCIe 5.1 compatibility. A native 12V-2x6 graphics-card cable, Zero RPM fan mode, industrial-grade capacitors, and quiet operation make it ideal for powerful modern gaming and workstation builds.
Product Overview
The CORSAIR RM850e provides efficient and dependable power for modern gaming PCs, professional workstations, and performance-focused custom builds. Its 850W continuous output offers ample capacity for powerful processors and graphics cards, while the fully modular design allows builders to install only the cables required by their system. This reduces cable clutter and helps improve airflow inside the case.
With 80 PLUS Gold efficiency, the RM850e delivers up to 90% operating efficiency under typical conditions, helping reduce wasted electricity, operating heat, and cooling requirements. It is officially certified for the Intel ATX 3.1 standard and supports PCIe 5.1 graphics hardware through an included native 12V-2x6 GPU cable. corsair.com
A quiet 120mm rifle-bearing cooling fan uses a carefully optimized fan curve to control temperatures without generating excessive noise. During lighter workloads, Zero RPM mode allows the fan to stop completely for near-silent operation. Internally, the RM850e uses a resonant LLC topology with DC-to-DC conversion and industrial-grade capacitors rated for operation at up to 105°C. corsair.com
The compact 140mm-long enclosure provides greater cable-management space than many conventional ATX power supplies. It also supports Modern Standby for fast wake-from-sleep performance and improved efficiency at low system loads.
Please confirm the exact regional part number before purchase, as included AC power cables and connector quantities can differ slightly between RM850e revisions and plug-type variants.
Please check the official manufacturer website for the latest and most accurate compatibility, clearance, radiator, fan, and I/O specifications before purchase or finalizing a build.
