ASUS ROG Falchion Ace 75 HE Hall Effect Gaming Keyboard
The ASUS ROG Falchion Ace 75 HE is a compact gaming keyboard built for competitive players who need faster response times and customizable switches without sacrificing portability. It combines Hall Effect magnetic switches with an 8000 Hz polling rate and on-the-fly actuation tuning, all in a 75% layout that fits easily into a carry case.
Why this product
8000 Hz polling rate for 0.125ms response
Refreshes input 8× faster than standard gaming keyboards, reducing delay to 0.125 milliseconds per keystroke.
Adjustable actuation from 0.1–3.5mm
Fine-tune the actuation point in 0.01mm steps using the onboard adjustment wheel, then toggle Rapid Trigger for the fastest repeat rate.
Hot-swappable ROG HFX V2 & V2X switches
Swap magnetic switches without tools. Each switch supports customizable actuation and works across all ROG HE platform keyboards.
Six-layer dampening absorbs noise
Three PORON® and three silicone layers suppress keystroke vibrations and pinging for cleaner acoustics during play.
Includes protective carry case
Travel-ready with a custom-fit case, keycap puller, and all cables included.

- Users who want precise control over actuation point tuning without opening the keyboard.
- Those seeking quieter keystrokes via the six-layer dampening system.
Trade-offs
- Users who prefer full-size keyboards; the 75% layout omits the numpad and some function keys.
- Mac or Linux users; software support is limited to Windows 10 and Windows 11.
- Those needing wireless connectivity; this keyboard is USB-wired only.
- Budget-conscious buyers; magnetic switches and Hall Effect sensors command a premium price.
The ROG Falchion Ace 75 HE builds on the success of the ROG Falchion Ace HFX with a roomier 75% layout, upgraded HFX V2 & V2X magnetic switches, and a new ROG Hall Sensor. It also introduces an adjustment wheel for effortless on-board tuning, while retaining the multifunction button, interactive touch panel, and the fan-favorite Rapid Trigger toggle. Plus, an 8000 Hz polling rate delivers lightning-fast response, ensuring every keystroke is registered with unmatched speed and precision.
ROG HE Platform
ROG HE is a new keyboard platform that features structural upgrades for improved stability and performance. It is a socket platform identifier for ROG keyboards using Hall Effect switches and supports hot-swappable magnetic switches. The magnetic switches can be shared across all supported ROG HE keyboards and will support future upgrades within the same socket.
ROG Hall Sensor
Delivers exceptional precision and accurate input detection, reduces electrical noise and interference, and increases magnetic flux limits for superior performance. Leveraging the increased magnetic flux tolerance of the HFX V2/V2X Magnetic Switch, each switch is further refined through precision calibration during manufacturing to enhance magnetic sensing accuracy without affecting saturation.
8000 Hz Polling Rate
A high-speed USB microcontroller delivers an 8000 Hz polling rate that refreshes input up to 8X faster than most gaming keyboards, reducing delay from 1 millisecond to a mere 0.125 ms. The theoretical response time for an 8000Hz polling rate is 0.125 ms, meaning your computer requests data from the keyboard every 0.125 ms. However, the actual end-to-end delay is also influenced by the travel distance of the switch and the processing speed of the device.
Six-Layer Dampening Design
The Falchion Ace 75 HE uses six dampening layers - three PORON® and three silicone layers - to absorb keystroke vibrations and pinging noise.
Protection and Portability
Built for gamers on the move, the custom-fit carry case shields your keyboard from impact and scratches, keeping it secure and ready for every match - anytime, anywhere.
