Corsair RM850 850W White Fully Modular Low-Noise ATX 3.1 PSU, 80 PLUS Gold, PCIe 5.1
High-Efficiency Power Delivery and Gold Certification
The Corsair RM850 White is designed to provide consistent, high-efficiency power to your gaming PC or workstation with an 80 PLUS Gold certification. This rating ensures up to 90% efficiency, significantly reducing energy overhead and heat production within your system. Built with premium industrial-grade capacitors, the RM series delivers the unwavering power and long-term reliability that enthusiast-level builds demand. The white aesthetic extends to the casing and the fully modular cables, making it the perfect centerpiece for clean, snow-themed setups where performance and style must go hand-in-hand.
ATX 3.1 Compliance and PCIe 5.1 Ready
Equipped with the latest industry standards, the RM850 is fully compliant with ATX 3.1, providing improved voltage regulation and superior transient response for modern hardware. It features a native 12V-2x6 cable, offering direct support for the most advanced PCIe 5.1 graphics cards without the need for cumbersome adapters. This future-proof connectivity ensures that your power supply is ready to handle the massive power excursions of next-generation GPUs, delivering up to 850W of stable energy to keep your high-end components running smoothly under even the most demanding gaming or rendering loads.
Low-Noise Operation and Zero RPM Fan Mode
Silence is a priority with the RM850, which utilizes a specially tuned 140mm rifle bearing fan designed for quiet operation even at full load. The fan curve is mathematically optimized to keep noise levels at a minimum, while the integrated Zero RPM Fan Mode ensures the fan shuts off entirely during low to medium loads. This results in virtually silent operation during everyday tasks like web browsing or document editing. Even when the action heats up, the fan remains whisper-quiet, ensuring that your focus stays on your game or your work rather than the hum of your power supply.
Fully Modular White Cables and Easy Installation
The fully modular cable system of the RM850 White allows you to connect only the cables your system requires, drastically reducing clutter and improving airflow within your chassis. Each cable is finished in a matching white sleeve, providing a professional and unified look for your build right out of the box. The flexible, low-profile design of these cables makes routing through tight spaces and behind motherboard trays a simple task. This focus on ease of use, combined with the compact 160mm-long casing, ensures that the RM850 fits comfortably into most modern PC cases while leaving plenty of room for effective cable management.
