Overview

The Endgame Gear OP1 8K v2 is a wired gaming mouse engineered for competitive FPS players. It features a custom PixArt PAW3950 optical sensor and a Nuvoton M483 high-speed MCU, enabling a polling rate of up to 8000Hz. Click latency averages just 70 microseconds, making it one of the fastest mice on the market. The shell is designed around a claw-grip optimized shape, measuring approximately 3.8mm shorter and 5.5mm narrower than the XM series. At roughly 47 grams, it's exceptionally lightweight, reducing fatigue during extended gaming sessions.

Connectivity & Compatibility

The OP1 8K v2 connects via USB Type-A using the included Flex Cord 5.0 paracable, which offers near-wireless freedom of movement when paired with a mouse bungee. It supports Windows 10 and later operating systems. To fully utilize the 8000Hz polling rate, a reasonably modern CPU is recommended. Firmware updates require the dedicated Endgame Gear software, available from the manufacturer's website.

Product Info

Released in late 2025, the OP1 8K v2 is available in Dark Frost (this model), Black, and White. The standard warranty is two years. Positioned firmly in the high-end segment, it competes directly with the Razer Viper 8KHz and Logitech G Pro X Superlight 2. Its key differentiators are the 8000Hz polling rate, ultra-low click latency, and lightweight design at a competitive price point.

Best Use Cases

First and foremost, this mouse is for competitive FPS and tactical shooter players. The 8000Hz polling rate and low-latency clicks provide a tangible advantage in titles like Valorant, CS2, and Apex Legends, where every millisecond counts. Second, it's ideal for claw-grip users. The flat sides and extended main buttons allow for flexible finger placement while minimizing accidental clicks, accommodating a wide range of hand sizes. Finally, it's a top choice for gamers seeking an ultralight mouse. At around 47 grams, it enables swift flicks and reduces wrist strain during long sessions, with no battery anxiety to worry about.
