Outstanding Audio
Combined onboard features deliver elevated audio
Intelligent design and premium hardware create audio quality unlike anything
you've ever experienced.
Audio Shielding
Separates analog/digital signal domains, significantly reducing multi-lateral
interference.
Separate Layer for Left and Right Tracks
Ensures minimal crosstalk between audio paths.
Premium Japanese Capacitors
Premium parts provide an immersive sound signature, with exceptional
fidelity.
Aura Sync | Outshine the Competition
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura
offers full RGB lighting control with a variety of functional presets for RGB
LED strips connected to the onboard RGB headers. And it can all be synced with
an ever-growing portfolio of Aura-capable hardware.
Addressable Gen 2 RGB Header
The addressable Gen 2 RGB header is now capable of detecting the number of
LEDs on second-gen addressable RGB devices, allowing the software to
automatically tailor lighting effects to specific devices. The new header also
offers backward-compatibility with existing Aura RGB gear.
Armoury Crate
Armoury Crate is a new software utility designed to give you centralized
control of supported products. From a single intuitive interface, Armoury Crate
