German PC accessory maker be quiet! expands beyond power supplies with its first gaming mice, the Dark Perk Ergo and Dark Perk Sym. The Ergo adopts a right‑handed, Logitech G403‑style silhouette, measuring 120 mm × 66 mm × 39 mm and weighing just 54 g. Its solid chassis leaves only four modest cutouts at the base. Founded in 2001, the firm earned acclaim for silent PSUs before entering peripherals.

Inside, the mouse houses PixArt’s PAW3950 sensor with a 32,000 CPI ceiling, paired with Omron D2FP‑FN2 optical switches for crisp clicks. Nordic’s nRF54H20 MCU delivers true 8000 Hz polling in wired or wireless mode, and the 1.75 m braided cable supports up to 4000 Hz. Battery life reaches roughly 110 hours at 1000 Hz. The mouse also supports DPI shift shortcuts via its side buttons.

Pricing lists the Dark Perk Ergo at $109.99 with a two‑year warranty, positioning it above many mainstream esports mice but below premium boutique offerings. Five programmable buttons plus a dedicated wheel click give ample customization, while the optional web driver mirrors the desktop IO Center software. For right‑handed gamers seeking a lightweight, high‑polling device, the Ergo delivers on its specifications. It feels solid.
