The Asus ROG Falchion Ace 75 HE is a wired mechanical gaming keyboard built in a compact 75% layout with a standard profile, connecting to a host system via USB with a detachable cable. It uses a gasket mount design and reaches a polling rate of 8000 Hz, placing it at the higher end of input reporting speeds. The keyboard measures 320 mm wide, 145 mm deep, and 35 mm thick, with a total weight of 668 g. It is not designed for Mac use, and comes backed by a one-year warranty.
The keyboard features a backlit layout with RGB lighting using south-facing LEDs, set into a case constructed from a combination of plastic and aluminum with an aluminum plate. It is available in two colorways — black and white — and includes adjustable feet to modify the typing angle. No wrist rest is included in the package.
This keyboard is equipped with the ROG HFX V2X Magnetic Switch, a Hall effect switch with a linear feel and an actuation force of 40 g. The total travel distance is 3.5 mm, while the actuation point can be set anywhere between 0.1 mm and 4 mm, offering a wide range of sensitivity adjustment. The switches are hot-swappable, allowing them to be replaced without soldering.
The keyboard supports rapid trigger, dual actuation, and adjustable actuation, giving users fine-grained control over how and when keystrokes register. Analog input and full N-key rollover (NKRO) are also supported, ensuring all simultaneous keypresses are recognized without conflict. On the other hand, the board does not include USB passthrough, a display, or support for QMK, ZMK, or VIA firmware customization.
The keyboard uses a standard ANSI (United States) layout with PBT double-shot keycaps in an OEM profile, and the key arrangement follows a standard layout without any non-standard sizing. Media controls are accessible via the Fn key rather than dedicated keys, and a rotary dial is included as an additional input element for quick adjustments.
