Description

Description

The Corsair RM850e is a top-quality, fully modular 850W computer power supply, specially designed to deliver quiet, stable, and energy-efficient operation in any modern PC build. It features official ATX 3.1 certification and full compatibility with the PCIe 5.1 protocol, including an integrated native 12V-2x6 cable capable of delivering up to 600W of power to the latest high-end graphics cards. With Cybenetics Gold energy efficiency certification, compact dimensions of just 140mm in length for easy cable management, and a 120mm fan with Rifle Bearing for low noise levels, the RM850e ensures maximum reliability. Its internal architecture is based on an LLC topology with DC-DC conversion and industrial-grade 105°C capacitors, providing absolute electrical stability backed by a 7-year manufacturer warranty.

Fully Modular Design & 12V-2x6 600W Cable

Keep the inside of your case perfectly organized thanks to the Corsair RM850e's fully modular design (Full Modular cabling). Connect only the cables your system needs, eliminating unnecessary clutter and improving airflow. The power supply includes a dedicated 12V-2x6 cable capable of delivering up to 600W, as well as multiple 8-pin PCIe connectors, fully covering the increased power demands of modern and future graphics cards (GPUs) and processors (CPUs).

Official ATX 3.1 Certification & PCIe 5.1 Compatibility

The Corsair RM850e is built according to the industry’s most stringent specifications, carrying official compatibility certification with the ATX 3.1 standard. This certification guarantees exceptionally high levels of stability, resistance to sudden load spikes (power spikes), and energy efficiency. Combined with full support for the PCIe 5.1 protocol, the power supply is a future-proof choice for powering the most demanding gaming systems and workstations.

Cybenetics Gold Energy Efficiency Certification

Ensure maximum energy savings and the lowest heat output thanks to the Cybenetics™ Gold energy efficiency certification. The Corsair RM850e delivers 850 Watt continuous power with an exceptionally high efficiency rating across all load levels. At the same time, it supports Windows Modern Standby, providing lightning-fast wake times from sleep mode and optimized power consumption during system idle.

Silent Operation & Compact 140mm Casing

With a compact chassis length of just 140mm, the RM850e installs with great ease even in the most space-constrained modern computer cases, leaving plenty of room for cable management. Its cooling is ensured by a quiet 120mm fan with Rifle Bearing technology. The fan uses a specially calculated rotation curve (fan curve) that keeps noise levels to an absolute minimum, even when the power supply is operating under its maximum load.

Advanced LLC Architecture with DC-DC & 105°C Capacitors

The internal design of the RMe series guarantees top-tier electrical performance and uninterrupted voltage stability. It incorporates a robust Resonant LLC topology with DC-DC conversion, delivering clean power to the +12V rail (62.5A) without fluctuations. In addition, it uses industrial-grade capacitors rated for 105°C, ensuring component longevity and the device’s seamless operation even at a continuous ambient temperature of 50°C.

Ultra-Flexible Cables & 7-Year Manufacturer Warranty

The package includes extremely flexible (ultra-flexible) embossed cables accompanied by low-profile combs, offering top-tier aesthetics and ease of routing. Corsair’s build quality and reliability are confirmed by the high mean time between failures (MTBF of 100,000 hours). The power supply comes with a 7-year manufacturer’s warranty, providing complete peace of mind and protection for your investment.
