Little Things Make a Big Difference
Prime Z490 series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.
Realtek Codec and Unique Design Features for Pristine, Powerful Audio
Prime Z490-A utilizes a unique audio codec designed in close collaboration with Realtek — the Realtek S1220A. It also features an unprecedented 120 dB signal-to-noise ratio for the stereo line out and a 113 dB SNR for the line in, providing pristine audio quality. Additionally, an impedance-sensing circuit automatically adjusts gain to ensure an optimal volume range for your headphones.
DTS:X® Ultra adds a spatial audio feature to boost headphones and speakers for enhanced gaming, VR, and extended-reality experiences. DTS:X Ultra supports sound based on channels, scenes, and objects to allow for deeper sonic immersion in enabled content. It also provides post-processing enhancements and device-level tuning for DTS® codecs.
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 the built-in RGB LEDs as well as strips and devices 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
Two addressable Gen 2 RGB headers are 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 headers also offer backward-compatibility with existing Aura RGB gear.
Armoury Crate is a new software utility designed to give you centralized control of supported products. From a single intuitive interface, Armoury Crate allows you to easily customize RGB lighting and effects for every compatible device in your arsenal. The software also provides control of settings for an ever-growing number of ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlight to help you stay in touch with the ASUS community.
Protect Your Graphics Card
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
