ASUS ROG Keris II Ace Wireless Gaming Mouse - 54g, 42K DPI
The ASUS ROG Keris II Ace is an ultralight 54-gram wireless gaming mouse designed for competitive FPS players who need precision and low latency without the weight penalty. It pairs a 42,000 DPI optical sensor with tri-mode connectivity and support for polling rates up to 8,000 Hz in wired mode, letting you choose speed over wireless convenience or vice versa without sacrificing either entirely.
Why this product
54 grams for competitive gaming
Shape and weight tested by esports professionals. Dropping 25 grams from the previous design lets it move faster across your mat without compromising ergonomics or durability.
Three ways to connect
Wired USB, 2.4 GHz RF wireless, or Bluetooth—each with dedicated polling rate support. Switch modes on the fly; the ROG Omni Receiver handles multiple devices wirelessly from a single dongle.
ROG AimPoint Pro sensor, 42K DPI
Optical sensor with less than 1% deviation for pixel-perfect tracking. Rated to 750 IPS and 50G acceleration; can even track on glass if needed.
8000 Hz polling in wired mode
Reaction time matters in competitive play. The ROG Polling Rate Booster pushes wireless to 4000 Hz and wired to 8000 Hz, cutting input lag to single-digit milliseconds.
ROG Optical Micro Switches rated for 100 million clicks
Instant actuation with no tactile delay. Crisp feedback designed to handle spam-clicking in fast-paced games without wearing out.

Best for
- Competitive FPS players who value low latency and sub-gram weight differences
- Esports competitors and streamers needing precision tracking and customizable lighting across an RGB ecosystem

Trade-offs
- Casual or budget-conscious buyers—the lightweight design, tri-mode connectivity and 8000 Hz wired polling are premium features not found in entry-level gaming mice.
- Mac or Linux users—Armoury Crate software requires Windows 10 or Windows 11 for full RGB and programmability.
- Users who need extended warranty or enterprise support—the standard 1-year warranty is typical for gaming peripherals but offers no accidental damage or extended coverage.
- Left-handed gamers—the Keris II Ace is shaped asymmetrically for right-hand use and is not available in a left-handed variant.
The ROG Keris II Ace is an ultralight 54-gram ergonomic gaming mouse with a shape tested by pro FPS players. Equipped with 42,000-dpi ROG AimPoint Pro optical sensor, ROG Optical Micro Switches and the ROG SpeedNova wireless technology, the Keris II Ace is also able to enhance gaming performance even further with the ROG Polling Rate Booster, which supports polling rates up to 8000 Hz in wireless mode.
Reaction time is everything in competitive games, so we designed the Keris II Ace in consultation with esports professionals to make sure we dialed in every feature exactly right. That all starts with the weight: despite being a wireless gaming mouse, we've dropped 25 grams off the previous design, allowing it to slide effortlessly across your mousemat.
The chassis features an ergonomic design made from environmentally friendly nylon derived from renewable castor oil, available in classic black or a stunning Moonlight White colorway. The Keris II Ace even comes with anti-slip grip tape if you need a little extra friction to keep the perfect grip.
The Keris II Ace features an all-new ROG AimPoint Pro optical sensor, with a 42,000 DPI and incredibly low deviation of less than 1% for incredible in-game precision. It's so accurate that it can even track on glass (though we don't recommend trying that at your next esports tournament appearance).
It also comes with a new Polling Rate Booster, which increases the Keris II Ace's polling rate to 4K in wireless mode and 8K in wired mode.
ROG Optical Switches bring crisp and instant actuation with a 100-million-click lifespan, letting you ping the objective as many times as it takes to get your team's attention.
You can adjust RGB lighting, performance and surface calibration settings, or program and map buttons with the Armoury Crate Gear software, made exclusively for the ROG Keris II Ace. To synchronize lighting across other Aura Sync products, install the original Armoury Crate to access an endless spectrum of colors, preset effects and wallpapers to take the style of your whole setup to the next level.
