Intel Z790 ATX motherboard for 12th to 14th Gen CPUs

This board uses the LGA 1700 socket and the Intel Z790 chipset to support 12th, 13th and 14th generation Intel Core, Pentium Gold and Celeron processors. It provides four DDR5 slots with a maximum capacity of 192 GB and dual-channel architecture. The ATX form factor fits standard chassis layouts.

Tool-free M.2 installation with four slots

The screwless M.2 Shield Frozr design lets you fit or remove M.2 drives without tools. The primary slot runs at PCIe 5.0 x4 from the CPU and accepts 22110, 2280 and 2260 lengths. Two further slots run at PCIe 4.0 x4 from the chipset and take 2280 or 2260 drives. A BIOS update may be required for some 14th generation processors.

192 GB DDR5 headroom and 5.8 Gbps Wi-Fi 7

Memory scales from JEDEC 4800 MHz up to 7800 MHz with XMP 3.0 overclocking, giving ample headroom for high-capacity kits. Networking uses Intel 2.5 Gbps LAN and Wi-Fi 7 with a 320 MHz channel for up to 5.8 Gbps throughput. Storage includes eight SATA 6 Gb/s ports and four M.2 connectors with RAID 0, 1, 5 and 10 support for both SATA and NVMe devices.

Questions about this item

How do I confirm the MAG Z790 TOMAHAWK MAX WIFI is running at full speed after setup?

Enter the BIOS and verify the CPU runs at its rated boost clocks, DDR5 memory shows the selected XMP profile speed, the primary M.2 slot reports a PCIe 5.0 x4 link, Wi-Fi 7 connects on a 320 MHz channel, and the Intel LAN negotiates a 2.5 Gbps link.

What comes in the box with the MAG Z790 TOMAHAWK MAX WIFI and what must I purchase separately?

The motherboard includes the I/O shield, Screwless M.2 Shield Frozr coolers for the four M.2 slots, and Wi-Fi 7 antenna. You must buy an LGA 1700 CPU, DDR5 memory modules, M.2 SSDs or SATA drives, and a power supply.

Which M.2 slot should I use for the fastest NVMe drive on the MAG Z790 TOMAHAWK MAX WIFI?

Install the highest-performance NVMe SSD in M.2_1, which is wired to the CPU and supports PCIe 5.0 x4 with up to 128 GB/s bandwidth; the other three slots run at PCIe 4.0 x4 from the chipset.
