Tenkeyless Silent Gaming Keyboard

The ARK DB-K4 Blade 87 is a tenkeyless mechanical keyboard built with pre-lubed linear silent switches for quiet operation. It targets office workers, dorm residents and late-night gamers who need low noise without sacrificing mechanical feel. The compact 87-key layout keeps the mouse closer for free swiping during play or work.

8000Hz Polling and Full NKRO

An 8000Hz polling rate delivers a 0.125ms response time for rapid input registration. Full N-key rollover with anti-ghosting ensures every keystroke is captured accurately during complex gaming combos or high-speed typing. The wired USB connection provides consistent bandwidth for competitive scenarios.

Gasket Mount with Hot-Swap Sockets

A gasket structure combined with sound-dampening foam absorbs vibration and hollow noise for a soft, cushioned typing feel that reduces finger fatigue. Hot-swappable sockets support both 3-pin and 5-pin switches, allowing switch changes in seconds using the included puller. RGB backlighting and DarkBeacon software enable key remapping, macros and AI-assisted lighting creation.

Questions about this item

Will the 8000 Hz polling rate work on my older motherboard that only has USB 2.0 ports?

The keyboard connects through a standard USB wired interface; the 8000 Hz rate is handled by the keyboard's own controller, so it will function on USB 2.0 ports, though the full polling benefit may be limited by the port's bandwidth.

How can I verify the 0.125 ms latency and 8000 Hz polling rate are active after I plug it in?

Install the DarkBeacon software — it reports the current polling rate and lets you confirm the 8000 Hz setting is applied; you can also run third-party input-latency tests to see the 0.125 ms figure in practice.

What comes in the box and do I need to buy switches or keycaps separately to start using it?

The box includes the 87-key tenkeyless keyboard, a keycap puller and a switch puller; silent linear switches and keycaps are already installed, so no extra parts are required unless you want to swap to different 3-pin or 5-pin switches later.
