Keyboard Cooler Master MK770 mechanical, USB + RF wireless + Bluetooth, QWERTY French, 99 keys, RGB, turquoise

The Cooler Master MK770 mechanical keyboard offers wired and wireless connectivity options including USB cable, RF wireless, and Bluetooth. It uses a French QWERTY 99-key layout with a numeric keypad and full RGB LED backlighting. Designed for multi-device use, the keyboard supports pairing with several devices and includes a 1.8 m cable for wired operation. Its construction features hot-swappable mechanical switches, Kailh Box V2 switches with factory lubrication, and PBT double-shot keycaps with high PBT content for increased durability.

Advantages

The MK770 combines hybrid connectivity and a compact 99-key French layout to serve both desktop and portable setups. Hot-swappable mechanical switches and pre-lubricated Kailh Box V2 switches enable smooth tactile feedback while the gasket structure, silicone dampers and EVA noise-absorbing elements reduce vibration and keystroke noise. Full RGB backlighting with individual key illumination and configurable lighting modes is supported by Master Control software that also manages macros and wheel control customization. The keyboard includes a three-way tactile wheel and factory-optimized stabilizers to improve key feel and reduce rattle.

Suitable for

• Typing and office work on a French QWERTY layout
• Gaming with tactile mechanical switches and low-latency wired or RF wireless modes
• Multi-device setups using Bluetooth for mobile devices and RF/USB for PCs
• Users who prefer durable PBT double-shot keycaps and customizable RGB lighting

How to use

Connect the keyboard via the supplied 1.8 m USB cable for wired use or switch to RF wireless or Bluetooth for untethered operation. Use the device-pairing function to connect multiple devices and switch between them according to the keyboard’s pairing instructions. Install the Master Control software on a compatible computer to configure backlighting, create macros, and assign functions to the three-way wheel. The hot-swappable design allows removing and replacing mechanical switches without soldering; follow standard hot-swap precautions and power down the keyboard before changing switches.

Recommendations

For the longest keycap and switch life, avoid exposing the keyboard to liquids and clean keycaps periodically. Use wired mode during competitive gaming to minimize latency, and use RF wireless or Bluetooth for mobile or casual use. If replacing switches, use compatible hot-swap switch types and handle components gently to preserve stabilizer and gasket integrity.
