Cooler Master MM831 – Shape & Fit Overview
The Cooler Master MM831 is a wireless ergonomic gaming mouse weighing 123g with dimensions of 128.1 × 67.4 × 43.4mm. Its middle-mounted hump makes it particularly well-suited for palm and claw grip styles.
For hand sizing, the MM831 fits best for hands measuring 183–233mm in length and 79–96mm in width. If your hand falls outside this range, use the MouseShape fit tool to find a mouse calibrated to your exact measurements.
At 123g, the MM831 is classified as full-weight. Heavier mice over 100g deliver a premium, planted feel that some players prefer for precise, deliberate aiming.
The PixArt PAW3335 sensor is a high-performance optical sensor delivering accurate, consistent tracking suitable for the most demanding competitive use. Maximum DPI is 32,000. Polling rate: 1000Hz.
