Compact Intel Z390 foundation

This Micro ATX board uses the Intel Z390 chipset and an LGA 1151 socket for 8th and 9th generation Core, Pentium Gold and Celeron processors. It targets builders who need a small footprint without losing the Z390 feature set. Dual-channel DDR4 memory runs at 2133 MHz and scales to 128 GB across four slots.

Expansion layout for daily builds

Two PCIe 3.0 x16 slots operate in x16 or x4 modes and a single x1 slot handles add-in cards. One M.2 E-key slot accepts Intel CNVi wireless modules only. Storage connects through two M.2 interfaces and four SATA III ports. Rear I/O supplies one USB 3.1 Gen2 Type-A port, four USB 3.1 Gen1 ports and 7.1-channel audio via the Realtek ALC892 codec with S/PDIF output. A Realtek 8111H NIC provides wired networking.

Thermals and power in normal use

The compact PCB keeps trace lengths short, helping voltage regulation stay cool under typical loads. Passive heatsinks on the chipset and power phases dissipate heat without adding fan noise. The 24-pin and 8-pin CPU power connectors feed the board efficiently, so a standard ATX supply runs the system quietly during everyday workloads.

Questions about this item

What does the Intel Z390 chipset limit memory speed to?

The board supports dual-channel DDR4 up to 2133 MHz, so the chipset caps memory at that frequency.

What size case and mounting points does this Micro ATX board need?

It follows the Micro ATX form factor and uses standard standoff positions for that size.

How is the CMOS battery fitted and which step is often skipped?

Place the supplied battery into the onboard holder with the positive side up and press until it clicks into place.
