Z390 ATX motherboard for 8th and 9th gen Intel Core

The ASUS Prime Z390-A uses the LGA 1151 (300 Series) socket and Intel Z390 chipset to support 8th and 9th generation Intel Core processors. Four 288-pin DDR4 slots accept up to 64 GB in dual-channel mode. The board provides three PCI Express 3.0 x16 slots, three PCI Express 3.0 x1 slots, six SATA 6Gb/s ports and two M.2 sockets for storage expansion.

Sustained-load behaviour with 5-Way Optimization

The 5-Way Optimization suite uses thermal telemetry to set a stable overclock in one click, keeping clocks consistent during long workloads. FanXpert 4 and a dedicated AIO pump header adjust cooling curves in real time so temperatures stay controlled under continuous stress. Intel I219-V LAN and 8-channel Realtek ALC S1220A audio maintain steady throughput without throttling.

Build quality and daily connectivity

SafeSlot Core reinforces the primary PCIe slots to withstand heavy graphics cards, while LANGuard and overvoltage protection shield network and power circuits. Two M.2 sockets accept 2242, 2260, 2280 and 22110 devices with both SATA and PCIe 3.0 x4 modes. AURA Sync RGB headers allow coordinated lighting across compatible components.

Questions about this item

Will this board run my 9th-generation Intel Core i7 without a BIOS update?

The LGA 1151 (300 Series) socket natively supports 9th and 8th generation Intel Core processors, so a compatible CPU will work out of the box.

Can I install four DDR4 sticks to reach the 64 GB limit?

Yes, the board has four 288-pin DDR4 slots running in dual-channel mode and supports up to 64 GB total capacity.

How many M.2 drives can I use at once and what lengths fit?

Two M.2 Socket 3 slots are provided: the first accepts 2242, 2260, 2280 and 22110 lengths in PCIe 3.0 x4 mode; the second takes 2242, 2260 and 2280 lengths in either SATA or PCIe 3.0 x4 mode.
