Intel Z390 ATX Motherboard

The MSI MAG Z390 TOMAHAWK is an ATX Intel motherboard built on the Z390 chipset for LGA 1151 (300 Series) processors. It supports 9th and 8th Generation Intel Core, Pentium Gold and Celeron CPUs. Four DDR4 slots accept up to 128 GB of memory in dual-channel mode. The board targets builders who need a full-size platform with extensive expansion room.

PCIe 3.0 And SATA 6Gb/s Limits

Three PCIe 3.0 x16 slots operate in x16/x4/x1 configurations alongside two PCIe 3.0 x1 slots for add-in cards. Six SATA 6Gb/s ports provide high-throughput storage connections, though bandwidth is shared with the M.2 slots. An M.2 Key E slot accepts only an Intel CNVi wireless module. The HDMI 1.4 output reaches 4096x2160@24Hz while DisplayPort 1.2 delivers 4096x2304@60Hz when a CPU with integrated graphics is installed.

Memory Capacity And M.2 Storage Headroom

Dual-channel DDR4 scales to 128 GB across four 288-pin slots with supported speeds ranging from 2133 up to 4400(OC). Two M.2 Key M slots each handle PCIe 3.0 x4 or SATA 6Gb/s drives in 2242, 2260, 2280 and, on the first slot, 22110 lengths. RAID 0/1/5/10 is available on the SATA array. Intel Optane memory readiness adds caching headroom for responsive system drives.

Questions about this item

Will this board fit in a standard ATX case and line up with the pre-installed I/O shield?

The board follows the ATX form factor and ships with a pre-installed I/O shield, so it mounts directly into any standard ATX chassis without a separate shield.

Which Intel processors are supported and do I need a BIOS update for 9th-generation CPUs?

The socket is LGA 1151 300 Series and supports 8th and 9th generation Core, Pentium Gold and Celeron CPUs; 9th generation chips work out of the box with the shipping BIOS.

How many M.2 drives can I install and what lengths do the two slots accept?

Two M.2 Key M slots are provided — the first takes 2242, 2260, 2280 and 22110 lengths, the second takes 2242, 2260 and 2280 lengths, both running at PCIe 3.0 x4 or SATA 6Gb/s.
