Core platform

The MSI MAG Z490 TOMAHAWK is an ATX motherboard built on the Intel Z490 chipset and the LGA 1200 socket. It supports 10th Gen and 11th Gen Intel Core processors along with Pentium Gold and Celeron CPUs for the same socket. Dual-channel DDR4 memory runs at speeds from 2133 MHz up to 4000 MHz with a maximum capacity of 128 GB.

Expansion fit

The board provides one PCIe 4.0 x16 slot when paired with an 11th Gen CPU and PCIe 3.0 x16 with a 10th Gen CPU, plus a second x16 slot wired for x4 mode and two x1 slots. Six SATA III ports and two M.2 interfaces handle storage, while dual LAN controllers — a 2.5 G Realtek and a 1 G Intel — serve networking. Users needing more than two full-length cards or more than six SATA devices should look elsewhere.

Deciding spec

The LGA 1200 socket and Z490 chipset combination determines compatibility; only 10th and 11th Gen Intel desktop processors fit this board, and memory must be DDR4. Verify your CPU generation and memory type before purchasing.

Questions about this item

How loud and hot does the VRM area get when the board runs a 10th or 11th Gen Intel Core processor all day?

The board uses an extended heatsink and 7W/mK thermal pad on the VRM section, keeping temperatures low enough for continuous full-load operation with 10th or 11th Gen Intel Core CPUs in the LGA 1200 socket.

What CPU cooler mounting hardware must I already own to install this LGA 1200 motherboard in my chassis?

You need a cooler that includes the LGA 1200 mounting kit or a separate LGA 1200 retention bracket; the board itself only supplies the socket and back-plate cut-out.

Will my existing PCIe 3.0 graphics card and SATA SSDs work at full speed alongside the Z490 chipset on this board?

Yes — the primary x16 slot runs at PCIe 3.0 with a 10th Gen CPU and the six SATA III ports operate at full 6 Gbps regardless of processor generation.
