Compact 65% form factor

The ASUS ROG Falchion Ace HFX is a 65% gaming keyboard with 68 or 69 keys in a black chassis. It uses ROG HFX magnetic switches that allow actuation points to be set between 0.1 mm and 4.0 mm. A detachable braided USB-A to USB-C cable connects the board, and per-key RGB lighting is included. It is built for competitive players who want a small footprint without losing programmable keys.

Sustained input behaviour

An 8000 Hz polling rate delivers a 0.125 ms response time for consistent speed during long sessions. Rapid Trigger and Speed Tap modes can be toggled for instant key repeat without debounce delay. Three-layer dampening foam and a silicone gasket mount absorb pinging sounds and keep the typing feel cushioned over hours of use. The magnetic switches maintain their actuation settings without physical wear.

Installation and common issues

Plug the detachable cable into a USB-A port and the keyboard is recognised on Windows 11 without extra drivers. Dual USB-C ports on the board allow quick switching between two PCs, but the second cable is not supplied. The interactive touch panel and multi-function button control volume, lighting and actuation on the fly. Users who need a dedicated function row or a palm rest should look elsewhere.

Questions about this item

Does the 8000 Hz polling rate increase power draw or heat during long sessions?

The keyboard draws power through its detachable braided USB-A to USB-C cable; the 8000 Hz rate adds no separate power supply or cooling requirement.

What must I already own to use the dual USB-C ports for two PCs?

You need two systems each with a free USB-C port and Windows 11, plus the two USB-C cables that connect to the keyboard's dual ports.

Will the 65% layout and PBT/ABS keycaps fit my existing keycap sets?

The 65% layout uses 68/69 keys with standard stem spacing; most MX-compatible sets cover the alphas but may lack the compact modifiers.
