The ROG Falchion Ace 75 HE is a wired 75% keyboard for players who want magnetic Hall-effect switches without giving up arrow keys and a function row. Its hot-swappable ROG HFX V2 switches let you set the actuation point anywhere from 0.1 to 3.5 mm in 0.01 mm steps, and a dedicated Rapid Trigger toggle turns fast reset on or off without opening software. An adjustment wheel, touch panel and LED light bar handle on-board tuning, and polling runs at 8000 Hz. Settings live in Gear Link, a browser-based tool, and a protective carry case is included.
Key features
ROG HFX V2 magnetic switches
The HFX V2 switch has 3.5 mm of travel, 32 gf initial force and 49 gf total force. Combined with the ROG Hall sensor, the actuation point can be set from 0.1 to 3.5 mm in 0.01 mm steps. The switches are hot-swappable on the ROG HE platform.
Rapid Trigger toggle and adjustment wheel
A physical switch turns Rapid Trigger on and off; by default it applies to the WASD keys only. Press the wheel to choose actuation point or Rapid Trigger sensitivity, then roll it to adjust, while the LED light bar shows the level in 0.1 mm segments.
8000 Hz and Speed Tap
A high-speed USB controller reports at up to 8000 Hz. Speed Tap (SOCD) mode, switched on with Fn + Caps, prioritises the most recent of two opposing keys such as A and D for quicker counter-strafing.
Built to travel
The 75% body measures 320 x 145 x 35 mm, uses an angled USB-C connector to keep the cable tidy, and comes with a custom carry case. The multi-function button and touch panel control volume, media playback and lighting.

FAQ
Is this the HFX V2 or V2X version?
This listing is the HFX V2 version in Black or White. The V2X-switch version is listed separately.
Do I need to install software?
No. The keyboard is set up in Gear Link, which runs in a web browser. ASUS lists Windows 10 and 11 as supported.
Can I use other brands' magnetic switches?
Not reliably. ROG places the magnet on the side of the switch, so switches with a centre magnet are not compatible. Use ROG HE-platform switches.
