This article covers Keychron G5 8K ワイヤレスマウス.

Overview

The Keychron G5 8K Wireless Mouse weighs just 43 grams, making it one of the lightest performance wireless mice on the market. Its shell is crafted from a carbon-fiber composite with a honeycomb texture for improved grip and ventilation. At the heart of the G5 8K is the PixArt PAW3950 optical sensor, offering up to 30,000 DPI and native 8,000 Hz polling rate for near-instantaneous cursor movements. The mouse supports three connection modes: 2.4 GHz wireless (with USB dongle), Bluetooth 5.3, and wired USB-C, ensuring compatibility with Windows, macOS, and Linux. Battery life is rated at up to 162 hours, and the included USB-C cable can be used while charging. Positioned in the mid-high tier of gaming mice, the G5 8K targets enthusiasts who demand both extreme lightness and high sensor performance. The online Launcher app (compatible with Chrome/Edge/Opera) allows deep customization of button mappings, macros, DPI steps, polling rates, and lift-off distance. Five onboard memory profiles let you carry your settings across different computers.

Connectivity & Compatibility

The G5 8K offers three connectivity options. The 2.4 GHz wireless mode uses a nano dongle stored inside the mouse and delivers the full 8,000 Hz polling rate with sub-0.125ms latency. Bluetooth 5.3 provides a stable connection for office or casual use, though polling rate is limited to 1,000 Hz. Wired USB-C mode is available for zero-latency gaming or when the battery is low. Compatibility spans Windows (7 or later), macOS (10.12+), and Linux (kernel 3.2+). All three modes work out of the box without additional drivers. The package includes the mouse, a 1.8m USB-C to A braided cable, a USB extender for the dongle, extra mouse feet, and a user manual.

Product Info

The Keychron G5 8K was released in late 2025 and is priced around ¥36,000 in Japan (approximately $240 USD). This places it in the upper mid-range segment, competing with other lightweight 8K wireless mice like the Razer Viper V3 Pro and the Logitech G Pro X Superlight 2. Keychron offers a one-year limited warranty. Key specifications include the PixArt PAW3950 sensor (30,000 DPI, 650 IPS), 8,000 Hz polling rate, five programmable buttons, and a 400mAh battery. The mouse measures approximately 125 × 64 × 39 mm. Weight is listed at 43g (excluding USB dongle).

Best Use Cases

Competitive FPS players: The 8,000 Hz polling rate reduces input lag to a fraction of standard 1,000 Hz mice, giving a tangible advantage in fast-paced shooters. However, achieving consistent 8K performance requires a moderately powerful CPU (e.g., Intel 12th-gen or AMD Ryzen 5000 series or better). Players on older hardware may want to stick with 4,000 or 2,000 Hz to avoid CPU overhead. Weight-optimization enthusiasts: At 43g, the G5 8K is among the lightest wireless mice you can buy. The carbon-fiber composite construction feels rigid despite the low weight. Users who prefer a heavier mouse for stability may find it too light. Multi-device workflow: Switch between a gaming PC (2.4 GHz), a work laptop (Bluetooth), and a tablet (Bluetooth) with a press of the bottom button. The dongle can be stored inside the mouse for travel. Tinkerers and macros users: The online Web Launcher offers extensive customization. You can assign media controls, keyboard shortcuts, or complex macros to any of the five buttons. Four DPI stages are accessible via the top button, and lift-off distance can be adjusted from 1mm to 2mm.
