Designed for 9th generation Intel® Core™ processors, the Prime Z390-A delivers maximum performance with customizable style. 5-Way Optimization provides AI overclocking and dynamic fan calibration while dual M.2 and USB 3.1 Gen2 delivers maximum transfer speeds. Aura Sync RGB with addressable headers customize your build. The overclocking module of AI Suite's 5-Way Optimization has been revamped for the Z390 platform. This new version quickly delivers overclocking results that would typically take days of manual tuning. With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. Also, with backward compatible USB 3.1 Gen 2 Type-A and reversible USB 3.1 Gen 2 Type-C ports, you'll experience ultimate connection flexability and blazing data-transfer speeds of up to 10Gbps. With Fan Xpert 4 you can map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU-intensive tasks. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
