Our Verdict

Razer BlackWidow V4 75%

Corsair K65 PLUS WIRELESS

The Razer BlackWidow V4 75% and the Corsair K65 PLUS WIRELESS are similar gaming keyboards with compact (75%) form factors. The most significant difference is that the Razer is wired-only, while the Corsair is a wired model that connects with a 2.4 Ghz receiver or via Bluetooth. The Razer performs better overall and supports a maximum polling rate of 8000Hz. It also comes stock with tactile switches and has a scroll wheel feature, while the Corsair has linear switches and a multi-function control knob that you can use to scroll or zoom and control backlighting and media volume.
