Corsair Nightsword v2 Adds Dedicated Stream Deck Button at $130

Key Takeaways

• The Nightsword v2 Wireless SD is detected as a native Stream Deck device, allowing full access to Stream Deck plugins and Multi-Action workflows
• Battery life reaches 170 hours with RGB off and 1kHz polling, or approximately 50 hours at 8,000Hz
• Priced at $130, it targets streamers and power users who want Stream Deck functionality without a separate hardware unit

A Gaming Mouse That's Also a Stream Deck

Corsair revealed the Nightsword v2 Wireless SD at Computex 2026. The mouse does something its competitors don't: the Stream Deck app recognizes it as part of the Elgato ecosystem. That means you can map Stream Deck actions directly to any of the mouse's 8 programmable buttons.

The standout feature is a dedicated Stream Deck Launch button. Press it, and a Virtual Stream Deck appears on your screen. You can then trigger any Stream Deck function from that overlay. No physical Stream Deck unit required.

“By effectively turning the mouse into an Elgato-supported peripheral, we've broken down the wall between hardware control and software automation.”

This isn't just about macro buttons. Because the mouse integrates with Stream Deck's software, you get access to the full plugin library. That includes integrations for OBS, Twitch, Discord, Spotify, and dozens of other streaming and gaming platforms. You can also set up Multi-Actions, which chain multiple commands into a single button press.

Specs: Marksman S Sensor and 8,000Hz Polling

The Nightsword v2 Wireless SD uses Corsair's Marksman S optical sensor. It maxes out at 33,000 DPI, tracks at up to 750 IPS, and handles 50G acceleration. This is the same sensor Corsair put in the Sabre v2 Pro Wireless and last year's Scimitar Elite SE.

The mouse supports 2.4GHz wireless, Bluetooth, and wired connections. Over 2.4GHz, it achieves an 8,000Hz polling rate. That's the same 8K spec we've seen marketed as a competitive gaming advantage in recent flagship mice.

Battery life is where things get interesting. Corsair claims up to 170 hours with RGB lighting disabled and polling set to 1kHz. At full 8,000Hz polling, expect closer to 50 hours. Both figures are well above average for wireless gaming mice.

Design and Build

The Nightsword v2 Wireless SD has a sculpted, right-handed ergonomic shape. It measures 129.6 x 78 x 40.9mm and weighs 89g. That weight puts it in the middle of the pack for wireless mice. Not ultralight, but not heavy either.

Primary switches are optical, rated for 100 million clicks. The mouse has 11 buttons total, with 8 of them programmable through either Corsair's iCUE software or Stream Deck's interface.

Not Corsair's First Stream Deck Mouse

The Scimitar Elite Wireless SE already offered Stream Deck integration. That mouse has a 12-button side panel, making it popular with MMO players who need lots of keybinds. But it treated Stream Deck as a bonus feature rather than a selling point.

The Nightsword v2 Wireless SD is different. The dedicated launch button and Virtual Stream Deck workflow suggest Corsair designed this mouse specifically for streamers and productivity power users. The Scimitar is for gamers who might also stream. The Nightsword v2 is for streamers who also game.

What the Community Is Saying

On Reddit's r/gamingpc, users praised the Virtual Stream Deck feature as a cost saver. A physical Stream Deck takes up desk space and costs $80 to $200. If you can get similar functionality from your gaming mouse, that's one less device to buy and manage.

HackerNews users were more skeptical. Some raised concerns about software bloat. The mouse requires Stream Deck 7.0 or later, and some commenters wondered whether running that software would affect performance on systems not built for streaming.

Pricing and Availability

The Corsair Nightsword v2 Wireless SD will retail for $130. That's premium pricing for a gaming mouse, but competitive if you factor in the Stream Deck integration. A Stream Deck Mini costs $80 on its own.

Corsair hasn't announced a specific release date yet. Given the Computex unveiling, expect availability in the coming months.
