Corsair K100 RGB Optical-Mechanical Gaming Keyboard - Elite PC Hub

Our review of the Corsair K100 RGB finds it is aimed squarely at serious PC gamers and content creators who want a fast, programmable keyboard with premium build and lighting. The single biggest reason to buy is its AXON Hyper-Processing plus OPX optical-mechanical switches, which deliver hyper-fast 1.0mm actuation and up to 4,000Hz polling for the most responsive input available in a wired gaming keyboard. It feels solid, customizable, and deliberately designed for long sessions and streaming workflows.

Key Features

• Durable aluminum frame: A sturdy chassis gives the keyboard a premium, long-lasting feel that resists flex during intense play.
• AXON Hyper-Processing Technology: Native 4,000Hz hyper-polling and 4,000Hz key scanning reduce input latency and allow complex layered lighting effects to run smoothly.
• OPX optical-mechanical switches: Hyper-fast 1.0mm actuation with linear travel offers extremely responsive keypresses and a long 150 million keystroke life.
• Per-key RGB and LightEdge: Dynamic per-key lighting plus a 44-zone three-sided LightEdge provide expansive customization for game feedback and ambience.
• iCUE control wheel and macros: A programmable control wheel and six dedicated macro keys integrate with Elgato Stream Deck for streamlined media and streaming control.

Who It's For

The K100 RGB is best for competitive and enthusiast PC gamers who prioritize the fastest possible input and deep customization, and for streamers who benefit from the six macro keys and Elgato Stream Deck integration. It also suits users who want a high-quality keyboard with durable PBT double-shot keycaps and a premium metal frame.

Casual typists or buyers on a tight budget should look elsewhere; the keyboard's advanced polling rates, dedicated streaming features, and premium materials are overkill if you only need a basic office or travel keyboard.
