Built for competitive typing

The Corsair K70 RGB MK.2 CH-9109011-NA is a full-size mechanical gaming keyboard with 104 Cherry MX Blue switches. Its clicky, tactile action gives clear feedback for every keystroke. A detachable palm rest supports comfort during long sessions. Per-key RGB backlighting allows full colour customisation across the board.

Upgrade from membrane or linear switches

Users moving from standard rubber-dome keyboards gain faster actuation and audible confirmation. The jump is worth it when you want distinct click feedback for typing or gaming precision. Three onboard profiles store lighting and macros without software. USB 2.0 passthrough adds a convenient port for a mouse or headset.

Simple plug-and-play setup

Connect the wired USB cable and the keyboard works immediately on any system with a USB 2.0 port. iCUE software unlocks advanced lighting sync and macro editing but is not required for basic use. The aluminium frame resists flex during intense play. Buyers who need wireless connectivity or a compact layout should look elsewhere.

Questions about this item

How much desk depth does the detachable palm rest add to the keyboard footprint?

The palm rest attaches magnetically to the bottom edge and extends the depth by roughly 8 cm, so allow that extra space in front of the 104-key layout.

Which USB ports must be plugged in for the keyboard and the pass-through to work?

Connect both USB 2.0 plugs — one for the keyboard itself and the second for the pass-through port — otherwise the extra port stays inactive.

How are the Cherry MX Blue switches serviced if a key starts chattering?

Switches are plate-mounted and not hot-swappable; replacing one requires desoldering the faulty switch from the PCB and soldering in a new Cherry MX Blue unit.
