CORSAIR RM1000x Overview

Gaming enthusiasts and workstation builders can leverage their high-end components and ensure enhanced electrical output with the Corsair RM1000x 1000W 80 Plus Gold Fully Modular ATX Power Supply.

Driving electrical performance while maintaining balance is a single 1000W +12V rail operating on the ATX12V Version 3.1 standard which supports high-end systems with a focus on gaming, editing, and designing. Multiple connectors support your components with four PCIe 6+2-pin connectors, seven SATA connectors, and four peripheral connectors. A dedicated 16-pin connector offers a single-cable solution for NVIDIA 40 series graphics cards. With the 80 Plus Gold efficiency certification, you get almost 90% efficiency at full loads. Fully modular cables allow you to pick and choose which cables you need for your system which reduces case clutter and enhances airflow. Low noise operation inhibits distracting sounds thanks to Zero RPM Fan Mode. A fan override knob allows you to manually change the airflow settings as needed.

Low-Noise Fan
A 140mm fluid dynamic bearing fan with magnetic dome structure keeps noise to a minimum. Enabling Zero RPM mode eliminates noise completely at low to medium loads.

Very Quiet

Inaudible when powering a 7900x and 5070 ti, and reduces the gpu's coil whine compared to my previous PSU. The fan speed knob lets me put a low minimum fan speed to keep the unit cool while making no noticeable noise.
