Product Description

Mercury V75- HE Gaming Keyboard

8000Hz Polling Rate, 0.005mm RT Precision, 256K Scan Rate

• True 8kHz Polling Rate: Boasts an 8000Hz USB polling rate paired with 256kHz key-position scanning, reducing latency to a near-instantaneous 0.125ms.
• ​GravaStar x Gateron Magnetic Jade Pro Switch: Engineered for 0.005mm precision with adjustable trigger depth (0.1mm–3.5mm) to eliminate lag and enhance control.
• Adjustable Actuation Point: Customizable trigger depth (0.1mm increments, 0.1mm–3.5mm) to suit playstyles—shallow for fast combos, deep for precise inputs.
• Dynamic Rapid Trigger: Dynamically adjusts activation/deactivation points based on key travel (not preset limits), enabling fluid rapid-fire key repeats.
• Last Keystroke Prioritization (LKP) + Snap Click: Prioritizes the last-pressed key for smooth directional changes; resolves simultaneous presses by favoring deeper inputs.
• Rapid Trigger Mode: Eliminates key "stiction" with instant reset on upward travel, enabling faster re-presses and input switching.
• Semi-Aluminum Construction: Combines a sturdy aluminum frame (for durability) with a premium plastic base (lightweight, modern desk aesthetic).
• Hot-Swappable Design: Allows switch swapping (no soldering) with magnetic Hall Effect switches; compatible with select TTC and Gateron models.
• 5-Layer Acoustic Foam: Minimizes keystroke vibrations for crisper sound and smoother typing feel.
• 16 Modes, Dual Systems, Multi-Zone RGB Lighting: Customizable 16 dynamic modes, dual-zone control (keys + ambient side lights), and adjustable hue/saturation/brightness.

Precision Trigger, Rapid Response, Enduring Performance

GravaStar x Gateron Magnetic Jade Pro Switch

Engineered for industry-leading 0.005mm precision and adjustable trigger depth (0.1mm- 3.5mm), they eliminate lag and keep you in control. Perfect for clutch plays in CS2, precise aiming in Valorant, or building a setup that stays sharp.

Adjustable Actuation Point​ Eliminate the slowest part of input lag: the initial key press travel before activation. With ​0.1-3.6mm adjustable trigger depth​ (in 0.1mm increments), tailor each key to your playstyle-shallow presses for lightning-fast combos, deep presses for intentional precision. Perfect for reducing accidental taps and optimizing response times in fast-paced games.
Dynamic Rapid Trigger​ Say goodbye to fixed reset points. This feature dynamically adjusts activation/deactivation points based on key travel distance, not predefined limits. Keys engage instantly on press and release immediately on release, enabling ​fluid, rapid-fire key repeats—ideal for gaming scenarios requiring split-second reactions (e.g., FPS aim, MOBA skill shots).
Last Keystroke Prioritization (LKP) + Snap Click​ LKP ensures smooth directional changes by prioritizing your last-pressed key, critical for games like Valorant or Apex Legends. Snap Click intelligently resolves simultaneous key presses: it favors deeper presses and auto-resets shallower ones, so you never miss a command. Together, they eliminate "input chaos" and sharpen your competitive edge.
Rapid Trigger Mode Rapid Trigger Mode eliminates key "stiction"-resetting keys instantly as they travel upward, so you can re-press and switch inputs faster than ever. No more waiting for keys to "bounce back"-execute rapid combos, skill shots, or direction changes with zero delay.

Meets Modern Design​

GravaStar V75 blends rugged durability with sleek aesthetics through its innovative ​semi-aluminum construction: a sturdy metal frame forms the backbone, ensuring structural integrity even during intense gaming marathons, while a premium plastic base adds a lightweight, modern touch to your desk setup.

Hot-Swappable Design

Tailor Your Keyboard To Perfection

GravaStar V75’s hot-swappable magnetic switches let you redefine your typing experience-swap out worn switches or experiment with new feels without soldering. While our magnetic switches use advanced Hall Effect technology for precise actuation.

Compatibility is limited to select TTC Switches and Gateron models (check our website for details).

5-Layer Acoustic Foam

Silence Meets Sensation

GravaStar V75’s enhanced acoustic foam system minimizes keystroke vibrations-delivering a crisper, more satisfying sound and a smoother typing feel. Whether you’re crushing FPS combos or typing up reports, this multi-layer design ensures every press feels deliberate, every click stays quiet, and your focus stays sharp.

16 Modes, Dual Systems, Multi-Zone RGB Lighting

Endless Customization​

GravaStar V75’s RGB backlighting system delivers 16 dynamic modes and dual-zone control—keyboard keys and side ambient lights sync for immersive visuals. Tweak hue, saturation, brightness, effect speed, or switch modes to craft your own signature look. Perfect for gaming with pulsating battle effects or typing under soft ambient glow—customize every detail, no limits.
