Compact 75% gaming keyboard

The ASUS ROG Falchion Ace 75 HE is a wired 75% keyboard with 83/84 keys and ROG HFX V2 magnetic switches. It targets competitive gamers who want adjustable actuation and an 8000 Hz polling rate in a compact form factor. The linear magnetic switches allow per-key actuation tuning from 0.1 to 3.5 mm in 0.01 mm steps. A protective carry case is included for transport.

Adjustment wheel and Rapid Trigger toggle

An onboard wheel lets you change actuation point and Rapid Trigger sensitivity without software. The interactive touch panel handles media playback and volume. The Rapid Trigger toggle enables the fastest key repeat for gaming. A web-based configurator provides deeper per-key customisation when needed. The package includes a keycap puller, a USB cable, a ctrl keycap, a ROG sticker and documentation.

Hot-swappable magnetic switches ease changes

The HFX V2 switches are hot-swappable, so you can replace them without soldering. Five-layer dampening with a silicone gasket mount reduces ping and creates a cushioned feel. Three tilt angles adjust typing angle for comfort. The 8000 Hz polling rate delivers a 0.125 ms response time over USB 2.0. Buyers who need a full-size layout or dedicated macro keys should look elsewhere.

Questions about this item

Will the ROG HFX V2 magnetic switches need to be replaced after heavy use?

The hot-swappable ROG HFX V2 magnetic switches can be removed and replaced individually without soldering, so only a worn switch needs swapping rather than the whole board.

What limits how low I can set the actuation point on the HFX V2 switches?

The actuation point is adjustable from 0.1 mm to 3.5 mm in 0.01 mm steps, so the 0.1 mm floor is the lowest setting the hardware allows.

How much power does the keyboard draw when running at 8000 Hz polling all day?

The keyboard connects via a single USB 2.0 cable and draws its power from that port; no external power adapter is required.
