Description

High Efficiency and Reliability

The Corsair RM850x power supply boasts an 80 PLUS Gold certification, which means it achieves high energy efficiency of up to 90% at typical loads. This high efficiency not only reduces operating costs but also minimizes heat generation, extending the lifespan of your components. The use of high-quality 105°C Japanese capacitors ensures a stable power supply and high reliability, even under demanding conditions.

Whisper-Quiet Operation with Zero RPM Mode

One of the standout features of the RM850x is its extremely quiet operation. Thanks to the Zero RPM fan mode, the 135mm fan remains completely off at low to medium loads. The fan only begins to spin when higher power draw is needed to cool the components. This intelligent mode ensures a virtually silent experience during everyday use, while the rifle bearing fan operates quietly and efficiently even under load.

Fully Modular Cable Management

The fully modular design of the RM850x allows you to connect only the cables you need. This significantly simplifies installation and cable management, as it avoids clutter from excess cables inside your case. The result is a clean, tidy PC build with improved airflow. The flat, black cables also blend aesthetically with any case design.
