Compact 97-key layout

The ASUS TUF Gaming K3 Gen II is a 96% optical-mechanical keyboard built for gamers who want a smaller footprint without losing the function row. Its 97-key arrangement frees desk space for mouse movement and fits easily into a travel bag.

IP57 rating and detachable top plate

The board carries an IP57 waterproof and dust resistance rating, so spills and debris can be rinsed away. A detachable top plate makes deep cleaning simple, while a silicone gasket mount with dampening foam reduces pinging noises for a quieter typing sound.

Per-key RGB with Armoury Crate control

Per-key RGB LEDs deliver 16.8 million colours that synchronise with other Aura Sync devices through ASUS Armoury Crate software. Eight programmable function keys (F1-F8) let you assign macros or lighting profiles without extra hardware. The package includes the keyboard, a quick start guide and a warranty card.

Questions about this item

What does the USB 2.0 interface cap the keyboard's polling rate at in practice?

The USB 2.0 connection supports the keyboard's full N-key rollover and 100% anti-ghosting performance without bandwidth bottlenecks.

What are the exact dimensions needed to fit this 97-key keyboard on a desk?

The keyboard measures 15.16 inches wide by 6.02 inches deep by 1.5 inches high, requiring that footprint plus cable clearance.

How do I install the keyboard and what step do users often miss when setting up per-key RGB lighting?

Plug the USB 2.0 cable into the PC; the keyboard works instantly, but per-key RGB control and Aura Sync require installing ASUS Armoury Crate software.
