Compact LGA 1151 board for 8th and 9th Gen Intel

This Mini ITX motherboard uses the Intel B360 chipset and the LGA 1151 socket for 300 series processors. It fits small-form-factor builds that need integrated Wi-Fi and a single full-length PCIe slot. The board delivers essential connectivity without the bulk of larger ATX designs.

Who this suits and who should look elsewhere

It suits builders assembling a compact desktop with an 8th or 9th Generation Intel Core CPU and up to 32 GB of DDR4 memory. It is not suitable for older LGA 1151 CPUs, for overclocking unlocked K-series chips, or for systems that require more than two memory slots or multiple x16 slots.

The spec that decides fit

The single PCI Express 3.0 x16 slot runs in x16 mode and also supports NVMe SSDs as boot devices. If the build needs a second graphics card, additional x16 lanes or a larger M.2 complement, this board will not meet those requirements.

Highlights

  • Supports 8th generation Intel Core processors on LGA 1151 socket
  • Dual-channel DDR4 memory up to 2666 MHz with 32 GB maximum
  • Ultra M.2 slot enables PCIe 3.0 x4 NVMe storage at 32 Gb/s
  • Intel I219-V Gigabit LAN plus 802.11 ac dual-band Wi-Fi module
  • Realtek ALC887 codec delivers 7.1 channel high-definition audio

Questions about this item

How much heat does the B360M-ITX/ac produce when running an 8th generation Core processor all day?

The board uses a 6-phase power design for the CPU socket, and the B360 chipset has a 6 W TDP, so sustained loads stay cool with a standard Mini-ITX case airflow.

Which DDR4 memory kit do I need to populate both 288-pin slots for dual-channel operation?

Install two DDR4 modules rated at 2666, 2400 or 2133 MT/s; the board supports up to 32 GB total in dual-channel mode.

Will my existing SATA 6.0 Gb/s SSD still work if I add an M.2 NVMe drive in the Ultra M.2 slot?

Yes, the Ultra M.2 socket runs over PCIe 3.0 x4 and does not share bandwidth with the four SATA3 ports, so both drives operate simultaneously.
