MSI MAG Z890 TOMAHAWK WIFI

Four internal SSDs and dual Thunderbolt for a planned Intel workstation

Check with my buildRead the specifications ↓
The decision

The MAG Z890 TOMAHAWK WIFI is useful when an LGA1851 workstation needs four internal M.2 positions and dual Thunderbolt 4. That is a stronger purchase reason than a generic premium-board label. List the external storage, docks and displays that will use those connections, then compare whether the B860 alternative already covers the actual workflow.

Consider it when

  • An ATX Core Ultra desktop with an explicit multi-drive and external-device plan.

Look again when

  • You have a simple one-drive build or expect every SSD socket to be Gen5.

The checks that can change your choice

Only the first recorded SSD link is Gen5

M2_1 is PCIe 5.0 x4; the other three are Gen4 x4, with M2_4 additionally supporting SATA M.2. Confirm sharing, supported lengths and cooling from the manual. The LGA1851 socket excludes older LGA1700 CPUs even when their memory generation matches.

Prove the complete platform

Find the exact processor in this board’s CPU support list and compare its required BIOS with the installed version. Then check the exact memory kit, occupied slots and front-panel connectors. A matching socket or a published maximum memory capacity is only part of that check.

Published specifications

LGA1851; ATX; Z890; four DDR5 slots; four M.2 storage slots; dual Thunderbolt 4; Wi-Fi 7; 304.8 × 243.84 mm.

Check the manufacturer CPU support list and installed BIOS version before buying. Matching socket and DDR generation do not prove CPU support, memory-profile stability, power-delivery suitability, or PCIe/M.2 lane availability.

A different choice worth checking

MSI MAG B860 TOMAHAWK WIFIThe MAG B860 TOMAHAWK WIFI provides three M.2 positions and Thunderbolt 4 for an ATX Core Ultra desktop build. Its appeal is a usable connection plan without automatically moving to the more elaborate Z890 model. If you have an existing LGA1700 CPU, treat this as a CPU-and-board replacement decision, not a motherboard-only upgrade.Read this model’s tradeoffs ↗ASUS ROG STRIX Z890-I GAMING WIFIThe ROG STRIX Z890-I GAMING WIFI fits LGA1851 and dual Thunderbolt 4 into Mini-ITX. It is a compelling layout when small size is part of the requirement, but fewer expansion positions make the initial storage and memory choices more consequential. Choose it after establishing the case, cooling and GPU arrangement, not merely because the feature list resembles a larger board.Read this model’s tradeoffs ↗MSI MAG Z790 TOMAHAWK WIFIThe MAG Z790 TOMAHAWK WIFI is worth comparing for an LGA1700 system with several internal drives: four M.2 positions and seven SATA ports distinguish it from simpler two-drive boards. Those connections can support a useful rebuild, but they do not create a path to LGA1851 processors. Compare the whole replacement platform cost if buying the CPU and memory from scratch.Read this model’s tradeoffs ↗
