Powered exclusively by 8th and 9th Generation Intel Core, Pentium Gold, and Celeron processors, the Prime Z390-A LGA 1151 ATX Motherboard from ASUS caters to daily users and content creators with well-rounded specs and features. Combining the benefits of Intel processors with essential ASUS design and engineering, the Prime Z390 provides a wealth of options for performance tuning via software and firmware features. This motherboard is designed to fit in ATX sized cases, supports the LGA 1151 socket, the Intel Z390 chipset, and is compatible with Windows 10 (64-bit).
The ATX form factor of the Prime Z390-A can support up to 64GB of DDR4 RAM over four dual-channel slots, or 16GB per slot at speeds of 4266 (OC) 4133 (OC), 4000 (OC), 3866 (OC), 3733 (OC), 3600 (OC), 3466 (OC), 3400 (OC), 3333 (OC), 3300 (OC), 3200 (OC), 3000 (OC), 2800 (OC), 2666, 2400, and 2133 MHz non-ECC unbuffered memory. For storage, there are six SATA III 6 Gb/s ports and two M.2 Socket 3 with M key, one of which supports type 2242, 2260, 2280, and 22110 PCIe 3.0 x4 SSDs, while the other supports type 2242, 2260, and 2280 SATA and PCIe 3.0 x4 SSDs.
There is also one USB 3.1 Gen 2 Type-C port (rear panel), three USB 3.1 Gen 2 Type-A ports (rear panel), two USB 3.1 Gen 1 Type-A ports (rear panel), two USB 2.0 Type-A ports (rear panel), one USB 3.1 Gen 1 Type-C connector (front panel), one USB 3.1 Gen 1 connector (mid-board) that support two additional USB 3.1 Gen 1 ports, and three USB 2.0 connectors (mid-board) that support an additional six USB 2.0 ports. For those looking to expand their system using PCIe, there are two PCIe 3.0/2.0 x16 slots (x16, x8/x8, x8/x4+x4, x8+x4+x4/x0), one PCIe 3.0/2.0 x16 slot (max at x4 mode), and three PCIe 3.0/2.0 x1 slots.
For delivering sharp, clear graphics, this motherboard supports Intel HD Graphics with HDMI and DVI-D outputs. HDMI supports a maximum resolution of 4096 x 2160 at 30 Hz and the DVI-D port supports a maximum resolution of 1920 x 1200 at 60 Hz. Integrated graphics has access to up to 1024MB of shared memory and also supports Intel InTru 3D, Quick Sync Video, Clear Video HD, and Intel Insider. For users looking to take advantage of multi-GPUs, the Prime Z390-A supports NVIDIA 2-Way SLI and AMD 3-Way CrossFireX technologies.
Using the 8-Channel Realtek S1220A HD audio codec, the Prime Z390-A can support audio with higher fidelity than standard controllers. Audio can also be output using the integrated five 3.5mm audio outputs or S/PDIF output. This motherboard is also equipped with features such as AI overclocking, OptiMemII, and M.2 heatsink, support for Intel Optane memory and a Thunderbolt 3 header, a TurboV Processing Unit (TPU), an Energy Processing Unit (EPU), Fan Xpert 4, Digi+ Power Control, Aura Sync, Crystal Sound 3, and more. Included is an ASUS Q-Shield, three SATA III 6 Gb/s cables, an M.2 screw package, an SLI HB Bridge (2-Way-M), a Q-connector, and a CPU fan holder. This motherboard is protected by a limited 3-year warranty.
Tune It Your Way
AI Overclocking results from a combination of CPU Potential, a proprietary algorithm that evaluates the CPU's capabilities, and Cooling Capability, an onboard intelligence that watches system vitals like temperatures, fan speeds, and power draw to gauge cooling performance. AI Overclocking then uses this intelligence to perform automated clocking and to provide target frequency and voltage estimations for veterans that prefer manual tuning.
