This article covers エンドゲームギア(Endgame Gear) OP1 8K 有線 ゲーミングマウス 8000Hz ポーリング PixArt PAW3395センサー Kailh GXスイッチ ブラック EGG-OP1-8K-BLK.

Overview

The Endgame Gear OP1 8K is a wired gaming mouse purpose-built for competitive FPS players. Its standout feature is support for an 8000Hz polling rate, sending positional data to the PC eight times more frequently than a standard 1000Hz mouse. This results in noticeably smoother cursor movement and lower input latency on screen. At its heart lies the PixArt PAW3395 flagship optical sensor, capable of up to 26,000 CPI, 650 IPS, and 50G acceleration. Motion Sync is supported up to 4000Hz polling, giving a near-instantaneous feel between hand movement and cursor tracking. The main clicks use Kailh GX mechanical switches, co-developed with Endgame Gear, offering a short, crisp actuation that enhances click precision during intense gameplay.

Connectivity & Compatibility

The OP1 8K connects via USB only, using a paracord-style Flex Cord 5.0 cable that is exceptionally soft and minimizes drag during use. It is compatible with Windows 10 and later. A dedicated software utility allows customization of button assignments, debounce time, polling rate, and lift-off distance (LOD) settings. The mouse features a hybrid skate design. It ships with small, balanced skates pre-installed, and includes a set of larger skates for softer mouse pads, allowing users to tailor glide feel to their preference.

Product Info

Released in early 2024, the OP1 8K sits in the mid-to-high tier of the gaming mouse market. Its key differentiator is the combination of 8000Hz polling and an ultralight body weighing approximately 49 grams. The manufacturer provides a 2-year warranty. The package includes the mouse, a spare set of large skates, and a tool for switch replacement. It is available through Japan and select PC hardware retailers.

Best Use Cases

This mouse is specifically optimized for claw grip users. The flat sidewalls allow fingers to move freely without being locked into a fixed position, making it ideal for players who rely on fine aim adjustments with a claw hold. It accommodates a wide range of hand sizes. Compared to the XM series, the OP1 is about 3.8mm shorter and 5.5mm narrower, making it a great fit for smaller hands while still being comfortable for larger hands in a relaxed claw. Competitive FPS players and tinkerers will appreciate the hot-swappable main switches. No soldering is required; simply unscrew the base, pull out the switch, and insert a different one from Endgame Gear's optional switch packs to customize click feel.

Things to Consider

The OP1 8K is a wired-only mouse. If you prefer a completely cable-free setup, this model is not for you. Running at 8000Hz polling can put additional load on the CPU. On lower-end systems, this may impact in-game frame rates, so consider your PC's capabilities before enabling the highest polling rate. Motion Sync is only supported up to 4000Hz polling. At 8000Hz, Motion Sync is automatically disabled. Also, the lightweight paracord cable, while flexible, may benefit from a mouse bungee to keep it from tangling on the desk.
