ATK Fierce X

Manufacturer: ATK

The ATK Fierce X is a right-handed gaming mouse built around a minimalist design philosophy, weighing just 42 grams while offering both wired USB and 2.4GHz wireless connection options. It runs on a rechargeable battery rated for up to 70 hours of use and connects wirelessly via Bluetooth 5 in addition to its primary 2.4GHz mode, giving users some flexibility in how they pair the device.

At its core, the Fierce X uses the PixArt PAW3950 Ultra sensor, which supports a DPI range from 50 to 30,000 and tracks at up to 750 IPS with a maximum acceleration of 50G. The polling rate reaches 8000 Hz, and all five buttons are programmable, though the mouse ships without onboard memory profiles. Its physical dimensions sit at roughly 119.57 mm in length, 60.99 mm wide, and 36.26 mm thick, and it includes a 1.8 m cable for wired use. There is no RGB lighting, no tilt scroll wheel, and no wireless charging support.

Pros
  • At 42 grams, the mouse is exceptionally light, reducing hand fatigue during extended use
  • The 8000 Hz polling rate ensures very frequent position updates, resulting in highly responsive cursor movement
  • DPI is fully adjustable across a wide range from 50 to 30,000, accommodating a broad variety of sensitivity preferences
  • All 5 buttons are programmable, offering flexible control customization
  • Battery life is rated at 70 hours, allowing for extended wireless use before needing a recharge
  • Supports both 2.4GHz wireless and Bluetooth 5, providing two wireless connection options
Cons
  • Cannot be used while charging, which means the mouse is out of action once the battery runs out until fully or partially recharged
  • Stores no onboard memory profiles, so custom settings cannot travel with the device independently
  • No RGB lighting is present, which may be a drawback for users who prefer visual customization
  • Warranty coverage is limited to one year
  • Designed only for right-handed users, excluding left-handed or ambidextrous users entirely
  • Does not support wireless charging, requiring a physical cable connection to recharge
Who is this for?

The ATK Fierce X is well matched to right-handed users who prioritize low weight and fast tracking in their gaming setup, particularly those playing titles where quick, precise movements are frequent. Its 8000 Hz polling rate and wide DPI range make it a practical fit for users who fine-tune their sensitivity settings regularly. The 70-hour battery life combined with 2.4GHz wireless connectivity also makes it a solid choice for those who prefer a cable-free desk environment without worrying about frequent recharging.

Who is this NOT for?

The mouse is not a good fit for left-handed users, as its shape is designed exclusively for right-handed ergonomics. Users who rely on onboard memory profiles to carry personalized settings between different systems will find the lack of that feature limiting. Additionally, those who need to keep working through a depleted battery will be hindered by the fact that the mouse cannot be used while charging, making it less practical in scenarios where uninterrupted session continuity is important.

Final Verdict

The ATK Fierce X positions itself as a stripped-down, performance-focused gaming mouse built around a clear set of priorities: minimal weight, responsive tracking, and reliable wireless connectivity. At 42 grams with an 8000 Hz polling rate and the PixArt PAW3950 Ultra sensor, it delivers a technically capable foundation for right-handed users who value precision and agility over feature richness. The 70-hour battery and dual wireless support add practical staying power, though the inability to use the mouse while charging and the absence of onboard memory profiles are constraints worth weighing depending on one's workflow. For users whose needs align with what the Fierce X actually offers — a lightweight, no-frills wireless gaming mouse with strong core tracking credentials — it represents a coherent and well-defined option within its category.
