ASUS ROG Keris II Ace — Wireless Gaming Mouse, White
AimPoint Pro 42,000 DPI, 750 IPS8000 Hz wired / 4000 Hz wireless, booster in boxTri-mode: 2.4 GHz / Bluetooth / wired54 g, right-handed ergonomic
The ASUS ROG Keris II Ace is a 54 g right-handed ergonomic wireless gaming mouse in white, built around the ROG AimPoint Pro optical sensor (100 to 42,000 DPI, 750 IPS, 50 G, tracks on glass) and ROG 100M optical micro switches. It is tri-mode — ROG SpeedNova 2.4 GHz, Bluetooth 5.1 and USB-C wired — and reaches 8000 Hz wired and 4000 Hz over 2.4 GHz through the ROG Polling Rate Booster, which is included in the box. ASUS publishes up to 107 hours on 2.4 GHz and 134 hours on Bluetooth at 1000 Hz with lighting off (67 and 89 hours with lighting on). Part number 90MP03N0-BMUA10, EAN 4711387394618. The Ace is the lightest Keris II at 54 g and the one that ships with the booster. Tell us your grip and hand size and we will confirm this is the right ROG shape for you.
Compatibility — check before buying:
Right-handed only — the thumb rest and side buttons are on the left, so it does not suit left-handed use. The included ROG Polling Rate Booster gives 8000 Hz on USB and 4000 Hz on 2.4 GHz per ASUS’s specification; without the booster the mouse runs at up to 1000 Hz. Switches are optical and not user-replaceable (the Keris II Origin has hot-swap sockets). The 2 m ROG Paracord cable, the receiver, a receiver extender, 100% PTFE feet and four pieces of grip tape are in the box. Bluetooth mode works on laptops and tablets but ASUS publishes no Bluetooth polling rate and no battery figure at 8000 Hz — the hours below are at 1000 Hz. Consumables (feet, grip tape, booster) are excluded from ASUS warranty.

Frequently Asked Questions
Does the Keris II Ace run at 8000 Hz wireless?
ASUS’s specification lists 8000 Hz on USB and 4000 Hz on 2.4 GHz with the included booster. We publish the specification figures.
Is it suitable for left-handed players?
No — right-handed ergonomic with the side buttons on the left. For a symmetrical ROG shape look at the Harpe II Ace.
Ace or Origin?
Ace: 54 g, optical switches, booster included, scroll-wheel lighting. Origin: 65 g, hot-swap mechanical switches, three lighting zones, longer battery, booster sold separately.
Can I use it for work over Bluetooth?
Yes — up to 134 hours on Bluetooth with lighting off, so it doubles as a laptop mouse without the receiver.
Singular Expert Insight
The Keris II Ace is the ergonomic ROG for competitive play: light, optical, and complete with the booster. Pick the Origin only if you want to swap switches or the longest battery; pick the Harpe II Ace if you prefer symmetrical. See how it compares with the other wireless mice we stock, and ask us to confirm the shape against your grip before you order.
Buyer’s Guide
Buy it if
You want a 54 g right-handed ergonomic mouse with optical switches, the polling booster included and 100-plus hours of battery.
Skip it if
You are left-handed, want hot-swap switches (Origin), or prefer a symmetrical shape (Harpe II Ace).
Also consider
The ROG Keris II Origin for hot-swap switches, or the Harpe II Ace for a 48 g symmetrical shape with native 8K.
