Overview

The Razer Viper (RZ01-02550100-R3M1) is a serious eSports gaming mouse that prioritizes speed and accuracy. At just 69 grams, its ultra-lightweight chassis allows for rapid, effortless movements. The star of the show is the Razer Optical Mouse Switch, which uses infrared light to register clicks with a response time of 0.2ms — three times faster than traditional mechanical switches — and eliminates debounce delay entirely. Powered by the Razer 5G Optical Sensor with 16,000 DPI native resolution and 99.4% tracking accuracy, the Viper delivers pinpoint precision demanded by professional gamers. The flexible Speedflex cable provides a near-wireless feel, reducing drag during intense gaming sessions. Its ambidextrous design accommodates both left-handed and right-handed users, with eight programmable buttons and Razer Chroma RGB lighting. ## Specifications | Item | Specification | | --- | --- | | Brand | Razer | | Model | Viper (RZ01-02550100-R3M1) | | Weight | 69g | | Sensor | Razer 5G Optical Sensor | | Max DPI | 16,000 | | Tracking Accuracy | 99.4% | | Max Speed | 450 IPS | | Number of Buttons | 8 | | Main Switches | Razer Optical Mouse Switch (70 million clicks) | | Cable | Speedflex Cable (2.1m) | | OS Support | Windows, macOS | | Dimensions (W×D×H) | 66mm × 127mm × 38mm | | Lighting | Razer Chroma (16.8 million colors) |

Connectivity & Compatibility

The Viper connects via a standard USB-A wired interface, offering plug-and-play compatibility. It works with Windows 7, 8, 10, and 11, as well as macOS 10.11 or later. Using the Razer Synapse software, you can remap buttons, adjust DPI in 100-step increments, and customize Chroma lighting effects. Onboard memory saves your profile directly to the mouse, so settings persist even when connecting to another PC without Synapse installed.
