This article covers SteelSeries Apex M800 Mechanical Gaming Keyboard JP 日本語配列ゲーミングキーボード 64179.

Overview

The SteelSeries Apex M800 is a mechanical gaming keyboard featuring the company's proprietary QS1 switches. This particular model comes in a Japanese (JIS) layout, making it ideal for Japanese users who prefer the localized key arrangement. The switches offer a 3mm total travel with a 1.5mm actuation point, enabling fast keystrokes for competitive gaming. It supports full N-key rollover (256 keys simultaneously), ensuring every press is registered even during intense gameplay. Connectivity is via two USB 2.0 cables, and the keyboard can be fully customized using the SteelSeries Engine 3 software. The per-key RGB backlight supports 16.8 million colors, allowing personalized lighting effects. The build quality is solid with a weight of 1,390g and dimensions of 510×174×41mm.

Connectivity & Compatibility

The keyboard connects to a PC using two USB 2.0 Type-A connectors. It is compatible with Windows 7 and later; macOS support is limited (software customization not available). The USB cable is 2m long, providing enough reach for most desktop setups. No additional drivers are required for basic keyboard function, but the SteelSeries Engine 3 software is needed for macro programming and lighting control. The Japanese layout is natively supported on Japanese Windows systems.

Product Info

Released around 2015, the SteelSeries Apex M800 remains available through and other retailers. The original MSRP was around ¥20,000, but current market prices (new or used) are approximately ¥8,000. The keyboard comes with a 1-year warranty for Japanese domestic units. Accessories include only the keyboard and USB cable; no wrist rest or keycap puller is included. Positioning-wise, this was a high-end keyboard at launch thanks to its unique QS1 switches and extensive customization, but today it competes in the mid-range segment against newer models with hot-swappable switches and more advanced software ecosystems.

Best Use Cases

Competitive gamers (FPS, fighting games): The 256-key rollover and shallow actuation point give a clear edge in fast-paced titles. Response is immediate and reliable. Not ideal for users who prefer a quieter, tactile typing experience. Power users who want deep customization: Full-key remapping, macro support, and per-key RGB lighting let you tailor the keyboard for gaming productivity or streaming. The software is mature but may feel dated compared to modern rivals. Casual users may not need this level of control. * Japanese layout enthusiasts: If you require a JIS keyboard for typing or gaming, this is one of the few high-performance mechanical options available. The full-size frame occupies significant desk space, so consider a tenkeyless model if space is limited.
