This article covers Glorious GMMK 3 PRO 75% Barebones Wired Silver US配列 MXメカニカルキースイッチ アルミボディ ベアボーンキット GLO-KB-GMMK3-PRO-75-BB-W-SIL-US KB0850.

Overview

The Glorious GMMK 3 PRO 75% Barebones Wired Silver is a premium barebone keyboard kit featuring a CNC-machined aluminum chassis in a compact 75% layout. As a barebones kit, it ships without switches or keycaps, allowing you to fully customize the typing experience with your choice of MX-compatible switches and keycaps. It connects via USB-C and offers a 1000Hz polling rate, making it suitable for both gaming and productivity. This model sits at the top of Glorious's GMMK lineup, targeting enthusiasts who demand build quality and customization. The solid aluminum frame provides excellent rigidity, while the Modular Gasket System (MGS) lets you swap internal gaskets to adjust the typing feel from stiff to bouncy. Dual-layer sound-dampening foam inside the case reduces unwanted resonance for a clean acoustic profile.

Connectivity & Compatibility

The GMMK 3 PRO uses a USB-C connection (USB-A to C cable included) for wired operation. It is compatible with Windows, macOS, and Linux without additional drivers. The US ANSI layout features 80 keys plus a rotary encoder; Japanese layout users may need to remap keys or swap keycaps. It supports both 3-pin and 5-pin MX-style mechanical switches via hot-swap sockets—no soldering required. This means you can use switches from Glorious, Cherry, Gateron, Kailh, and many others. Keycaps with a standard MX cross stem are also interchangeable.

Product Info

Released in late 2024, the GMMK 3 PRO 75% Barebones is priced around ¥36,000 on Japan (as of June 2026). It comes with a 2-year manufacturer warranty. Included accessories: USB-C cable, keycap puller, and switch puller. The only color option is Silver. In the market, this is a high-end barebone keyboard. It competes with models like the Keychron Q1 Pro and Drop CTRL, but stands out with its modular gasket system and CNC aluminum build quality.

Best Use Cases

Custom keyboard enthusiasts: Ideal for those who enjoy hand-picking switches and keycaps. The ability to swap gaskets and add foam allows deep tuning. However, you'll need to budget extra for switches and keycaps. Gamers: The 1000Hz polling rate and rigid aluminum body handle intense gaming sessions well. You can choose linear switches for fast actuation or tactile switches for precision. Note that the 75% layout lacks a numpad, so MMO players may want a separate numpad. Programmers and writers: The gasket mount reduces finger fatigue during long typing sessions, and the dampened sound profile is less distracting. For maximum quietness, pair with silent switches. Aesthetic-focused users: The silver aluminum finish looks premium on any desk. The understated 3-zone RGB adds a subtle glow. Be aware that the all-metal construction makes it heavy, so it's not portable.
