Corsair unveiled the Nightsword v2 Wireless SD Stream Deck gaming mouse at Computex 2026. This right‑handed wireless mouse includes a dedicated Stream Deck launch button, and because Corsair owns Elgato, the integration is done in‑house rather than through a third‑party partnership. The mouse brings Elgato’s shortcut system directly to the device, allowing gamers, streamers and creators to fire app, game and workflow commands without needing a separate desktop panel.
**Stream Deck controls are now under your thumb**
The Nightsword v2 Wireless SD appears as a device inside the Stream Deck app. After pairing, users can map Stream Deck actions to any mouse button and open virtual Stream Deck menus via the dedicated launch button. Once configured, shortcuts can be set for Discord, mic muting, audio levels, game launches, app switching, or multi‑step macros. In‑game, these shortcuts can handle commands, emotes or repetitive actions, while for streaming or productivity they cut down the clicks required to mute a mic, launch a tool, or hop between frequently used applications. The mouse also accesses plugins and profiles from the Elgato Marketplace, giving creators more flexibility to craft app‑specific controls beyond basic button remapping.
**The mouse still packs serious gaming hardware**
Beyond the Stream Deck button, the Nightsword v2 Wireless SD is built as a high‑performance gaming mouse. It features an ergonomic right‑handed shape, a sculpted thumb rest, 11 programmable buttons and three‑zone RGB lighting, weighing just 89 g. The device uses Corsair’s Marksman S optical sensor with DPI ranging from 100 to 33,000 in 1‑DPI steps, optical switches rated for up to 100 million clicks, and supports an 8,000 Hz polling rate. Connectivity options include 2.4 GHz wireless, Bluetooth 5.2 + LE, and wired USB. Battery life reaches up to 170 hours on 2.4 GHz with RGB off at 1,000 Hz polling, or 47 hours at 8,000 Hz polling; with lighting on, Corsair lists up to 42 hours at 1,000 Hz and 25.5 hours at 8,000 Hz. Bluetooth mode offers up to 164 hours without backlighting.
The Nightsword v2 Wireless SD is priced at $129.99 and is currently available through Corsair’s official website.
