Overview

The Endgame Gear OP1 8K is a wired gaming mouse built for competitive esports, where every millisecond counts. It features the PixArt PAW3395 optical sensor, capable of up to 26,000 CPI, 650 IPS, and 50G acceleration. The standout spec is the 8000Hz polling rate, which reduces input latency to just 0.125ms — far faster than the typical 1000Hz mice. This makes it one of the most responsive mice on the market. The shell is specifically designed for claw grip users. The sides are flat instead of the usual inverted-V shape, giving fingers more freedom of movement. The main buttons extend to the side edges, preventing accidental clicks. The weight is kept low (around 53g) thanks to the perforated interior structure, though the outer shell remains seamless.

Connectivity & Compatibility

The OP1 8K is a wired mouse with a USB-A to USB-C paracord cable (Flex Cord 5.0). The cable is attached to the mouse and cannot be removed. To achieve the full 8000Hz polling rate, a compatible USB controller and sufficient CPU power are required. The mouse works with Windows 10/11 out of the box. A dedicated software utility allows customization of button assignments, debounce time, polling rate, and lift-off distance. macOS support is limited to basic mouse functions without the software.

Product Info

Released in late 2023, the OP1 8K is priced around $79–$89 USD (approx. ¥12,000 in Japan). Endgame Gear offers a 2-year warranty. The package includes the mouse, Flex Cord 5.0 cable, a set of large skatez, and a sticker sheet. The mouse positions itself in the mid-to-high performance tier, offering enthusiast-grade features like 8000Hz polling and hot-swappable switches at a price that undercuts many competitors.

Best Use Cases

Competitive FPS and esports players: The 8000Hz polling rate dramatically reduces input lag, giving an edge in fast-paced shooters like Valorant, CS2, or Overwatch. The Motion Sync feature (supported up to 4000Hz) smooths cursor movement for better tracking. Claw grip users: The flat side profile and extended button design make this mouse one of the best for claw grip. It accommodates a wide range of hand sizes, from small to large. Enthusiasts who love customization: The screwless switch replacement system lets you swap main switches without soldering. You can buy optional switch packs to change the feel and actuation force. Users who prefer wired peripherals: No battery anxiety, no wireless interference — just a stable, low-latency connection. The paracord cable is light and flexible, minimizing drag. However, the 8000Hz mode can increase CPU load, so older systems may need to lower the polling rate. Also, palm grip users may find the shell too short for comfortable full-hand support.
