Overview

The SteelSeries Apex 9 TKL is a tenkeyless gaming keyboard built around optical switch technology. Its compact 355mm width frees up desk space for mouse movements, making it a strong contender for competitive gaming setups. The keyboard features OptiPoint optical switches with an ultra-low 0.2ms response time and adjustable actuation points of 1.0mm or 1.5mm, allowing users to fine-tune sensitivity for different game genres.
Beyond speed, the Apex 9 TKL emphasizes durability. The keycaps are made of double-shot PBT plastic to prevent letter wear, and the chassis uses an aluminum alloy frame rated for twice the structural rigidity of standard plastic boards. With onboard memory for five custom profiles and per-key RGB lighting, it balances esports performance with everyday reliability. The keyboard connects via a detachable USB-C cable, making it easy to pack for LAN events.

Connectivity & Compatibility

The Apex 9 TKL is a wired-only keyboard that connects through a USB Type-C to USB-A cable (included). It is fully compatible with Windows 7 and later operating systems; basic keyboard functionality works on macOS and Linux, but the full customization suite (SteelSeries Engine) is optimized for Windows. There is no wireless or Bluetooth connectivity.
The US English 87-key layout omits the numeric keypad, which is ideal for users who prioritize mouse space. The detachable USB-C cable allows for quick storage and replacement if damaged.

Product Info

Released in September 2022, the SteelSeries Apex 9 TKL sits in the mid-to-high tier of gaming keyboards. Its street price is around ¥14,900, which is competitive for an optical-switch board with adjustable actuation. The package includes the keyboard, a USB-C to USB-A cable, a keycap puller, and a product information guide. SteelSeries offers a 1-year manufacturer warranty.
What sets this keyboard apart in its price range is the combination of optical switch technology and variable actuation points. It directly competes with other TKL optical keyboards but adds the convenience of on-the-fly profile switching and a durable aluminum frame.

Best Use Cases

  • Competitive FPS and esports players: The 1.0mm actuation point and 0.2ms response give a literal edge in twitch-based aiming, while the tenkeyless layout provides extra room for low-sensitivity mouse swipes. The adjustable actuation also suits players who switch between sniping and close-quarters combat. Not ideal for MMO players who rely on a numpad for macros.
  • Gamers with limited desk space: Whether in a dorm room, small apartment, or LAN party setup, the Apex 9 TKL's compact footprint frees up valuable surface area. The detachable cable adds to portability. However, users needing a full-size layout for productivity or spreadsheet work should look elsewhere.
  • Durability-focused buyers: The PBT double-shot keycaps and aluminum frame resist wear and flex far better than ABS and plastic chassis keyboards. With 100-million-press rated switches, this keyboard is built for years of heavy daily use. That said, the optical switches produce a sharper, louder sound than most mechanical switches, so noise-sensitive environments may be an issue.
