This article covers Razer Viper 8K Hz ゲーミングマウス 8倍以上の高速性 8000Hzポーリングレート 20000 DPI Focus +センサー 軽量71g 柔らかい布巻ケーブル Chroma ライティング 【日本正規代理店保証品】 RZ01-03580100-R3M1.

Overview

The Razer Viper 8K Hz is a wired gaming mouse that pushes the polling rate envelope to 8000Hz—eight times the standard 1000Hz. Weighing just 71g and featuring the second-generation Razer Optical Mouse Switch alongside the Focus+ optical sensor (up to 20,000 DPI), this mouse is engineered for competitive esports. Its ambidextrous design suits both left- and right-handed users.
Unlike most wired mice, the Viper 8K Hz uses Razer's HyperPolling technology to send position data up to 8,000 times per second, resulting in ultra-smooth cursor movement and reduced input latency. This is especially noticeable on high-refresh-rate monitors (240Hz and above). The mouse connects via a flexible Speedflex cable that minimizes drag.

Connectivity & Compatibility

The Viper 8K Hz connects through a standard USB Type-A port. The cable is fixed (non-detachable) but uses a braided, flexible Speedflex material that reduces cable drag. It works plug-and-play on Windows 10/11 and macOS (with limited software features). Full customization, including button remapping and DPI staging, requires Razer Synapse 3. The mouse is compatible with PCs and some consoles via USB, but advanced features are PC-only.

Product Info

Released in 2021, the Razer Viper 8K Hz sits between mid-range and high-end gaming mice. Its original MSRP was around ¥12,000, but it now sells for approximately ¥6,400 on Japanese online retailers—excellent value for the performance. The warranty is 2 years from Razer. The package includes only the mouse; no extra grips or cable tie are included. It is widely available from Razer's official store and major retailers.

Best Use Cases

This mouse is built for competitive FPS gamers. The 8000Hz polling rate provides a tangible advantage in twitch shooters like Valorant or CS2, where every millisecond counts. To fully benefit, pair it with a high-refresh monitor over 240Hz.
It also suits left-handed gamers who need an ambidextrous shape with side buttons on both sides (two per side). The symmetrical design makes it a rare choice for lefties in the esports scene.
Finally, it's ideal for users transitioning to a lightweight mouse but uninterested in wireless. The 71g weight reduces fatigue during long sessions, and the wired connection eliminates battery anxiety. However, if you need wireless freedom or more than 8 programmable buttons (e.g., for MMOs), consider other models like the Razer Naga or a wireless Viper Ultimate.
