Verdict

The Corsair M65 RGB Ultra is a high-performance FPS gaming mouse featuring a durable anodised aluminium frame and the Corsair Marksman optical sensor, which delivers a native 26,000 DPI, 650 IPS tracking, and 50G acceleration. Key characteristics include 8 programmable buttons with a dedicated sniper button, Omron optical switches for rapid response, and a six-axis gyro supporting programmable tilt gestures and ultra-low lift-off distance. Its main pros are the 8,000Hz hyper-polling rate (wired) for minimal latency, a customisable weight system (97g–115g), and high-quality 100% PTFE feet for a smooth glide. Notable cons include a relatively high base weight that may not suit competitive players preferring ultra-light mice, a stiff rubber cable on the wireless model's charging port, and a shape that can be uncomfortable for users with extra-large hands or those who prefer a palm grip.

What customers dislike about Corsair M65 RGB Ultra?

  • Relatively heavy even without additional weights, which may not suit competitive FPS players
  • The wide shape and specific ergonomics may be uncomfortable for those with small hands
  • Not ideal for palm grip users as the mouse can feel too short or small for that style
  • Wired version features a stiff rubber cable that can hinder smooth movement
  • iCUE software is required for full customisation and can be resource-intensive
  • Some users report historical durability concerns with the scroll wheel axle
  • Lack of a free-scrolling mode or left/right tilt on the scroll wheel
