The CORSAIR K100 RGB Optical-Mechanical OPX keyboard is built for players who want fast, responsive actuation with a premium look and highly customizable lighting. Designed around CORSAIR OPX optical-mechanical keyswitches and CORSAIR AXON Hyper-Processing Technology, it delivers up to 4,000Hz hyper-polling and 4,000Hz key scanning for rapid input response—ideal for competitive FPS and fast-paced MOBA sessions where timing matters. With a durable aluminum frame, per-key RGB backlighting, and a 44-zone three-sided RGB LightEdge, it becomes a centerpiece for any setup while staying practical for everyday gaming and productivity.
Powered by CORSAIR OPX optical-mechanical keyswitches, this keyboard is tuned for hyper-fast input with a 1.0mm actuation distance and smooth linear travel. Compared to slower actuation designs, the shorter distance helps reduce the time between your press and the registered input—useful for rapid movement, quick ability triggers, and consistent rhythm in aim training. If you prefer a linear feel for gaming (rather than a tactile bump), the OPX setup supports precise control during sustained engagements and repeated key presses.
CORSAIR AXON Hyper-Processing Technology enables a high-performance gaming experience by delivering your inputs up to 4x faster with native 4,000Hz hyper-polling and 4,000Hz key scanning. In practical terms, this helps maintain responsiveness during intense gameplay where multiple actions happen quickly. It also supports driving 20-layer lighting effects, so your RGB setup can stay visually rich without sacrificing the responsiveness you expect from a gaming keyboard.
The K100 RGB supports full key rollover (NKRO) with 100% anti-ghosting, which is especially valuable when you press multiple keys at once—such as movement plus abilities, complex combos, or coordinated commands in team-based games. This reduces the risk of missed or mixed inputs, making it a strong choice for players who rely on consistent key combinations. For productivity use, NKRO also benefits fast typing and shortcut-heavy workflows where multiple keys may be pressed together.
Enjoy dynamic per-key RGB backlighting and a 44-zone three-sided RGB LightEdge that adds depth to your desk lighting. The keyboard is compatible with CORSAIR iCUE software, allowing you to manage backlighting and create custom effects. Beyond visuals, the iCUE ecosystem supports advanced control options, making it easier to match your lighting to your gaming profile or daily routine. If you like switching between moods—such as calmer lighting for work and brighter effects for gaming—this keyboard’s programmable lighting approach is designed to fit that style.
For faster in-game actions, the keyboard includes six dedicated macro keys that are fully programmable for complex macros and key remaps in iCUE. It also supports special streaming commands through Elgato Stream Deck software, which can be helpful for content creators who want quick scene or command triggers. Media control is handled with dedicated hotkeys, a volume roller, and an iCUE control wheel—useful for adjusting audio without leaving the game. A dedicated WIN Lock hotkey helps prevent accidental interruptions during intense sessions.
This is a wired gaming keyboard with a USB interface. It includes USB pass-through via USB 2.0 Type-A and supports keyboard connectivity through 2 x USB 3.0 or 3.1 Type-A. The keyboard also features on-board memory of 8MB and can store up to 200 profiles depending on complexity, which is convenient if you want your settings available across different sessions. For power and charging, battery charging is listed as supported, and the keyboard cable is braided for durability and a cleaner desk setup.
A magnetic detachable wrist rest is included, cushioned with a soft textured leatherette cover to support comfortable long sessions. This can help reduce strain during extended gaming nights or long typing periods. The keyboard is sized as “Extended,” supporting a layout intended for full-feature gaming control rather than a compact minimal footprint. With a weight of 1.31kg, it feels substantial on the desk, which many gamers prefer for stability during fast, frequent movements.
The CORSAIR K100 RGB Optical-Mechanical OPX keyboard comes with a 2-year warranty, giving you added confidence for long-term use.
