Overview
The Corsair Nightsword RGB is a wired gaming mouse built for FPS and MOBA players who demand precise weight and balance customization. Its standout feature is the built-in weight system: two weight sets with six mounting positions let you adjust the total weight from 119g to 141g, and the Corsair iCUE software can automatically detect the center of gravity in real time, helping you fine-tune the balance to match your grip and playstyle. Under the hood, a custom PixArt PMW3391 optical sensor delivers native 18,000 DPI with 1 DPI step adjustments, ensuring pixel-perfect tracking. Ten fully programmable buttons with durable Omron switches, a comfortable rubberized grip, and dynamic 4-zone RGB lighting round out the package. It's a mouse that rewards tinkerers who want their peripherals to feel truly personal.
Connectivity & Compatibility
The Nightsword RGB connects via a braided USB cable (approximately 1.8m). It is plug-and-play on Windows 10/11 and macOS 10.14+, with no additional drivers required for basic functionality. For full customization—button remapping, DPI profiles, macro recording, RGB lighting effects, and the real-time weight-balance detection—you need to install Corsair iCUE software. The mouse is right-handed ergonomic, designed for palm or claw grip with medium to large hands. The large PTFE feet provide smooth gliding on most mouse pads. It does not support wireless connectivity, so you'll need to keep the cable connected at all times.
Product Info
Released in 2019, the Corsair Nightsword RGB sits in the mid-to-high tier of gaming mice, targeting enthusiasts who value adjustability over raw lightness. Its weight-tuning system is unique in this price range, offering over 120 possible weight/balance configurations. The mouse comes with a 2-year warranty and includes two weight sets and a quick-start guide. The cable is braided and terminates in a USB Type-A connector.
Best Use Cases
FPS Gamers: The ability to dial in both weight and center of gravity makes the Nightsword RGB ideal for players who want consistent, repeatable aim. You can shift the balance forward for sniping or rearward for flick shots. However, if you prefer ultra-light mice (under 70g), this mouse will feel heavy even at its minimum weight. MOBA/RTS Players: With 10 programmable buttons, you can assign abilities, items, or macros directly to the mouse, reducing keyboard hand movement. The iCUE software allows complex macro sequences. But if you prefer a minimalist button layout, consider a simpler mouse. * Productivity Users: The high-precision sensor and comfortable ergonomics make it suitable for long work sessions. You can create a low-DPI profile for precise cursor control in design software. The wired connection ensures zero latency, but those who hate cable drag may want a bungee or a wireless alternative.
