Compact Z390 board for small-form-factor builds

The ASRock Z390M-ITX/ac is a Mini-ITX motherboard built on the Intel Z390 chipset with an LGA 1151 socket that accepts 8th and 9th generation Intel Core processors. It provides two DDR4 memory slots supporting dual-channel operation up to 32 GB and a single PCI Express 3.0 x16 slot for a graphics card. An Ultra M.2 socket handles M Key drives from 2230 to 2280 lengths, and six SATA3 connectors offer RAID 0, 1, 5 and 10. Onboard Intel I219-V LAN, Wi-Fi 802.11 ac and Realtek ALC892 7.1 channel audio complete the platform.

Suited to compact overclocking rigs.

This board suits builders who want Z390 overclocking features in a Mini-ITX footprint and need integrated Wi-Fi 802.11 ac plus wired networking. It will not work with 6th or 7th generation LGA 1151 processors despite the shared socket, so owners of those CPUs must choose a 100 or 200 series board instead. Users requiring more than two memory slots, multiple PCIe x16 slots or front-panel USB 3.1 Gen 2 headers should look at larger ATX or micro-ATX Z390 models.

The LGA 1151 (300 Series) socket decides

Only 8th and 9th generation Intel Core CPUs fit this socket; earlier LGA 1151 processors are physically identical but electrically incompatible and will not boot. Verify your processor generation before purchase, as no BIOS update can enable older chips on the Z390 chipset.

Highlights

  • Supports 9th and 8th Gen Intel Core processors on LGA 1151 socket

Questions about this item

What PCIe generation does the single x16 slot use, and what bandwidth does that cap the GPU at?

The board provides one PCI Express 3.0 x16 slot running in x16 mode, so a graphics card is limited to PCIe 3.0 bandwidth.

What physical clearance does the Mini-ITX form factor and the vertical M.2 Key E slot with bundled Wi-Fi module require in a case?

The board fits any Mini-ITX chassis, but the vertical M.2 Key E socket occupies the rear I/O area, so the case must allow a module to protrude upward from the motherboard edge.

How is the bundled Wi-Fi 802.11 ac module installed, and what step do builders often miss?

Insert the module into the vertical M.2 Key E socket, secure it with the screw, then attach the two antenna cables to the gold connectors on the module before fitting the I/O shield.
