Description
The GravaStar Mercury V75 HE is a competition-grade wired Hall Effect mechanical keyboard engineered for gamers who demand split-second responsiveness. Boasting a True 8kHz polling rate and 256kHz key-position scanning, it slashes latency to a near-instantaneous 0.125ms. Its custom GravaStar Blackcore UFO HE switches deliver 0.005mm Rapid Trigger precision with fully adjustable actuation points from 0.1mm to 3.6mm. Pro features like Dynamic Rapid Trigger, Last Keystroke Prioritization (LKP), and Snap Click eliminate input chaos during intense matches. The 5-layer acoustic foam structure and hot-swappable PCB combine premium sound with versatility, while multi-zone RGB lighting and a semi-aluminum frame complete this futuristic powerhouse for Windows and macOS.

True 8kHz Polling Rate
The V75 boasts a blazing 8000Hz USB polling rate, paired with 256kHz key-position scanning, delivering a True 8kHz polling experience that slashes keyboard latency to a near-instantaneous 0.125ms. This means your commands reach the game engine eight times faster than a standard 1000Hz keyboard, giving you a measurable edge in competitive titles where every millisecond counts.
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), you can tailor each key to your playstyle—shallow presses for lightning-fast combos, deep presses for intentional precision. This flexibility is perfect for reducing accidental taps and optimizing response times in fast-paced games.
Dynamic Rapid Trigger & Rapid Trigger Mode
Say goodbye to fixed reset points. Dynamic Rapid Trigger adjusts activation and deactivation points based on real key travel distance, not predefined limits. Keys engage instantly on press and release immediately on release, enabling fluid, rapid-fire key repeats. Rapid Trigger Mode further eliminates key “stiction”—resetting keys instantly as they travel upward—so you can re-press and switch inputs faster than ever with zero delay.
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 during counter-strafing and split-second decision-making.
GravaStar Customized UFO HE Switches & Acoustic Perfection
Experience flawless consistency with a perfectly balanced 40gf end force and a massive 100-million click lifespan. The switches are engineered for 0.005mm RT precision—instantaneous response for complete, unflinching control. Meanwhile, a meticulously designed multi-layer structure with premium PORON and silicone foams eliminates hollow resonance for a pure, satisfying typing experience.
Design, Comfort & Customization
Stay comfortable during marathon sessions with a 19mm ergonomic curve, curved front profile, and softened edges designed to eliminate wrist fatigue. The semi-aluminum construction combines a sturdy aluminum frame with a lightweight premium plastic base, while the hot-swappable PCB lets you swap magnetic Hall Effect switches without soldering. Limitless RGB illumination offers 16.7 million brilliant colors and 16 dynamic lighting effects with dual-zone control.
