Get to Know the CORSAIR Marksman S 33K DPI Sensor

A 33,000 DPI sensor is a high-caliber precision sensor enabling sub-millimeter movement detection with extraordinary consistency. Whether you’re working at 800 DPI or 12,000 DPI, you’ll benefit from more granular tracking, lower latency, and a sharper response curve. Compared to our previous Marksman sensor, the Marksman S has over 26% higher DPI.

This means:

• Movements feel immediate and deliberate.
• Small adjustments (like sniping or digital artwork) feel surgical.
• Fast swipes don’t outpace the sensor or lose fidelity.

Even if you never touch 33K DPI, having a sensor capable of that resolution ensures performance headroom that keeps up as your resolution scales, from 1080p to 4K. When you dial in your preferred DPI, you’ll find it more precise and accurate than ever.

The Marksman S is rated to track at speeds of up to 750 inches per second, an increase of 25% over our previous Marksman sensor. That’s more than enough speed to keep up with a 180° flick on a massive 4K display without dropping a pixel.

This matters in high-speed games like Counter-Strike 2, Valorant, or Marvel Rivals, where sweeping movements can play an important role. When you suddenly spin 180° to track a flanking opponent, the last thing you want is sensor loss or stuttering. For the low DPI player, this becomes your lifeline when needing to lock on to a tricky opponent. The Marksman S ensures that even the most aggressive inputs are recorded accurately. No prediction, no acceleration artifacts, just raw fidelity and your movements replicated as you intended.

In real-world gaming, you don’t just move slowly, your movements span across flick, snap, and twitch. Acceleration tracking is the sensor’s ability to register how quickly you start moving and how well it interprets sudden changes.

With support up to 50g, the Marksman S captures rapid bursts of movement with stunning clarity. Quick scopes, directional flicks, and panic dodges register cleanly. There’s no “catching up” or smoothing to wait for, you get instant reaction time that matches your reflexes.

It’s easy to focus on performance and forget what’s happening behind the scenes. Sensors are always sampling, tracking, and calculating. That takes power and the Marksman S has been designed not only to outperform its predecessor but to do so with significantly lower power draw.

• 27% less power consumption when running at 8K polling over USB
• 33% less power in wireless mode at 1K polling

This means longer wireless battery life, less heat, and more efficient performance across a wide range of devices.

High-stakes MMO moments such as dodging a boss's lethal AoE, sprinting to revive a downed teammate, or perfectly timing a burst rotation, every movement matters. With the CORSAIR Marksman S, your mouse becomes an extension of your will. No lag. No drift. Just pure surgical accuracy.

• Need to quickly strafe out of a one-shot zone? The 750 IPS speed ensures your twist happens the instant you react.
• Camera not cooperating mid-raid? Quick flick across your screen with buttery-smooth flow and zero stutter to reset your camera.
• Pulling off complex skill rotations? The sensor's pinpoint tracking keeps your cursor stickied to your action bar macros for accurate twitch selection.

Coupling our high-performance sensor with the 16 customizable buttons on the SCIMITAR ELITE WIRELESS SE, you unlock a new higher level of precision and control. Whether you're leading the charge in World of Warcraft, clutching a PvP duel in Guild Wars 2, or navigating chaotic boss mechanics in Final Fantasy XIV, the Marksman S gives you that feeling of complete authority. You’ll feel the real difference every second you’re in-game.

Sensor technology often gets overlooked, overshadowed by flashy RGB or high polling rates. The sensor is the core of your mouse experience, and the Marksman S is the sensor that elevates every click, every drag, every flick.

You won’t just notice it, you’ll come to rely on it. It’s the difference between a movement that feels “fine” and one that feels fluid, natural, and dialed in.

Whether you're a competitive gamer, a creative professional, or just someone who appreciates high-performance tools, the Marksman S delivers on every level: resolution, responsiveness, and reliability.

The CORSAIR Marksman S isn’t just a new sensor; it’s a milestone in mouse tracking technology engineered for the needs of tomorrow’s users while delivering tangible advantages today. If you want your gear to keep up with your ambition, your instincts, and your environment, the Marksman S is built for exactly that.

This is tech you can feel every time you move.
