Cooler Master MK770 Wireless

Manufacturer: Cooler Master

The Cooler Master MK770 Wireless is a full-size mechanical keyboard built around a gasket mount design, offering a layout that retains a numpad while trimming down the overall footprint to a 98% form factor. It supports wireless use via both 2.4GHz and Bluetooth 5.1, as well as wired connection through a detachable USB cable, giving users flexibility in how they connect it. The case combines plastic and aluminum construction and is finished in gray, with RGB backlighting and adjustable feet rounding out the physical build.

Switch-wise, the MK770 Wireless ships with Kailh Box V2 Red switches, which are mechanical clicky units requiring 45 g of actuation force across a total travel distance of 3.6 mm. The board supports hot-swappable switches, so replacements can be made without soldering. Keycaps are PBT double-shot in an OEM profile following a standard ANSI layout, and the keyboard includes N-key rollover for full simultaneous key input. A rotary dial is present on the board, while media functions are accessible via an Fn key layer. The polling rate runs at 1000 Hz over wired and 2.4GHz connections.

Pros
  • Hot-swappable switches allow for easy switch replacement without soldering
  • Tri-mode connectivity via USB, 2.4GHz wireless, and Bluetooth 5.1 offers flexible usage options
  • Gasket mount construction provides a more cushioned typing feel compared to standard tray mounts
  • N-key rollover ensures every simultaneous keypress is accurately registered
  • PBT double-shot keycaps are durable and resistant to shine over time
  • A detachable cable adds convenience when switching between wired and wireless use
Cons
  • At 1052 g, the keyboard is relatively heavy for a wireless board, reducing portability
  • No wrist rest is included, requiring a separate purchase for extended comfort
  • Media controls are only accessible via the Fn key layer, with no dedicated media keys
  • The keyboard is not designed for Mac, limiting out-of-the-box compatibility for macOS users
  • Lacks advanced input features such as rapid trigger or adjustable actuation, which some gaming keyboards in this category offer
Who is this for?

This keyboard suits users who want flexible wireless connectivity without committing to a single connection method, as the combination of USB, 2.4GHz, and Bluetooth 5.1 covers a wide range of setups. The gasket mount and hot-swappable switches make it a solid choice for those who enjoy customizing their typing experience without technical barriers, whether swapping switches or fine-tuning feel. The full 98% layout with a numpad also appeals to users who need a complete key set for productivity or data entry while still keeping the board relatively compact.

Who is this NOT for?

Users who prioritize portability or lightweight travel use will likely find the 1052 g weight inconvenient for carrying between locations regularly. The absence of advanced input features such as rapid trigger or adjustable actuation makes this board a poor fit for competitive gamers who rely on precise actuation customization for fast-paced gameplay. Additionally, macOS users looking for a plug-and-play experience may encounter limitations, as the keyboard is not designed with Mac compatibility in mind.
