The Corsair K65 Plus Wireless keyboard is distinguished by its minimalist design that focuses on functionality rather than elaborate aesthetics, making it one of Corsair's premier products. It operates at a 1000Hz polling rate for smooth performance in both gaming and typing.

The construction of the K65 Plus Wireless includes durable PBT keycaps with dye-sublimated legends, a heavy steel plate, internal foam, silicone dampening, and a large 4,200mAh battery, ensuring a sturdy build. Design-wise, it features a USB-C charging port, dongle storage, and switches for power and connectivity on the top, as well as a unique lighting button on the side for easy adjustment of lighting settings.

The keyboard features Red linear switches for a pleasing typing feel and includes a hot-swappable function for switch customization. A key feature of the K65 Plus Wireless is its comprehensive functionality, offering a 2.4GHz USB dongle and Bluetooth connectivity for multiple devices, and is compatible with various platforms including PC, Mac, Xbox, and PS5. It boasts an extended battery life of up to 266 hours without RGB lighting and includes media controls and a volume wheel for added convenience, with customization available via iCue software.

The keyboard is noted for its typing experience, with switches designed for a tactile feel and quieter operation. It allows for the swapping of compatible switch types to tailor to user preferences.

The design and functionality of the keyboard are further enhanced by features like instant RGB lighting control, a battery life indicator, and switches for connectivity and operating system compatibility, catering to both Windows and macOS users. While the keys have a single-shot PBT coating for a smooth feel, some may prefer a double-shot coating for enhanced durability, though this is a minor issue given the keyboard's overall capabilities.
