Overview

The Endgame Gear OP1 8K v2 is a wired gaming mouse built for competitive esports. Its headline feature is an 8000Hz polling rate, which sends positional data to your PC eight times per millisecond—dramatically reducing input lag compared to standard 1000Hz mice. This is paired with a custom PixArt PAW3950 optical sensor that supports up to 32,000 CPI (at 4000Hz) or 10,000 CPI (at 8000Hz), with CPI adjustable in 10-CPI steps and lift-off distance configurable in 0.1mm increments. The combination delivers pixel-perfect tracking and instant response, especially valuable in fast-paced shooters. The shape is purpose-built for claw grip: flat sides allow thumb and ring finger freedom, while the extended main button shell reduces accidental clicks and provides a comfortable resting spot. The mouse is slightly smaller than Endgame Gear's XM series—about 3.8mm shorter and 5.5mm narrower—making it approachable for smaller hands yet still usable for larger ones with a relaxed claw hold.

Connectivity & Compatibility

Connectivity is via a wired USB Type-A connection using the included Flex Cord 5.0 paracable, which is exceptionally flexible and minimizes drag. Compatible with Windows 10/11, macOS, and Linux. To fully utilize the 8000Hz polling, your system's USB controller must support high bandwidth—modern PCs (Intel Z490 / AMD B550 or newer) are fine, but older hardware or USB hubs may cause stability issues. Direct connection to a motherboard USB port is recommended. No Bluetooth or wireless option is available.

Product Info

Released in 2025, the OP1 8K v2 is priced around ¥13,600 (~$90 USD) in Japan via , positioning it in the mid-to-high tier for wired gaming mice. It competes with other 8000Hz models from Razer, Logitech, and VAXEE but stands out with its hot-swappable switch design and custom Kailh GX switches. The package includes the mouse, an extra set of large skatez, a switch removal tool, and a user manual. Manufacturer warranty is 2 years.

Best Use Cases

First and foremost, this mouse is a top pick for competitive FPS players—especially those playing Valorant, CS2, or Overwatch. The 8000Hz polling and low click latency (~70 microseconds average) shave off precious milliseconds, giving you a slight but tangible edge in reaction-heavy duels. Claw grip users will feel right at home thanks to the optimized shape; palm grippers may find it too small. Second, modding enthusiasts will appreciate the hot-swappable main switches. Without any soldering, you can replace the Kailh GX switches with other compatible mechanical switches to fine-tune click feel and durability. The bundled extra skatez also let you swap between small and large feet depending on your mousepad surface. However, if you prioritize cable-free convenience or need many extra buttons for MMOs or productivity, look elsewhere. Also, the 8000Hz feature demands a capable CPU and USB subsystem—on lower-end PCs, you might not see a benefit. For casual gamers, a 1000Hz mouse is still perfectly adequate and cheaper.
