Z390 Micro ATX motherboard for 8th

The GIGABYTE Z390 M fits a Micro ATX chassis and accepts 8th or 9th Generation Intel Core i7, i5 or i3 processors through its LGA 1151 socket. Four DDR4 slots support up to 128 GB of memory running at 2666 MT/s. It is aimed at builders who need a compact board with full Z390 overclocking features.

LGA 1151 socket and Intel Z390 chipset

The single specification that decides compatibility is the LGA 1151 socket paired with the Intel Z390 chipset. Only 8th and 9th Generation Intel Core processors fit this socket. The chipset unlocks CPU overclocking and provides 24 PCI Express 3.0 lanes for graphics and storage expansion.

128 GB DDR4 capacity and dual M.2 slots

Four 288-pin slots hold up to 128 GB of DDR4 2666 memory, giving ample headroom for multitasking and content creation. Two M.2 sockets and six SATA 6 Gb/s ports handle multiple SSDs and hard drives. The board runs out of internal expansion after two PCI Express 3.0 x16 slots and three PCI Express x1 slots are populated.

Questions about this item

What does the 128 GB maximum memory mean for a build using this Z390 M board?

You can install up to 128 GB of DDR4 across the four 288-pin slots, allowing large workloads or heavy multitasking on supported 8th and 9th Gen Intel Core i7, i5 or i3 processors.

How does the PCI Express 3.0 x16 interface limit graphics or add-in cards on this board?

Two full-length slots run at PCI Express 3.0 x16 speeds, so each card is capped at the 3.0 bandwidth ceiling rather than newer 4.0 or 5.0 rates.

What physical clearance and connectors does the Micro ATX Z390 M need to fit and power up?

The board uses the Micro ATX form factor with a 24-pin ATX power connector and a 12 V CPU power connector, plus standard front-panel, fan and SATA headers for case wiring.
