MSI MAG Z890 TOMAHAWK WIFI — LGA1851 ATX with PCIe 5.0, two Thunderbolt 4 ports, Wi-Fi 7 and 5G LAN

An Intel Z890 ATX motherboard for Intel Core Ultra (Series 2) processors on socket LGA1851. MSI feeds the CPU from a 16+1+1+1 Duet Rail design with 90A smart power stages on a 6-layer, 2oz-copper PCB, and gives it PCIe 5.0 x16 for the graphics card, four M.2 slots (one PCIe 5.0 x4), DDR5 up to 9200+ MT/s (OC), two rear Thunderbolt 4 ports, Wi-Fi 7 and Intel Killer 5G LAN.

1

Intel Socket LGA1851 — Centre

Takes Intel Core Ultra (Series 2) desktop processors. Game Boost, Memory Boost and a dedicated clock generator for BCLK tuning are in Click BIOS X.

2

16+1+1+1 Duet Rail VRM — Top & Left

Sixteen 90A smart power stages feed Vcore, fed by two 8-pin CPU power connectors. Heavy-plated VRM heatsinks sit on 7W/mK MOSFET pads with extra choke pads.

3

4 × DDR5 DIMM slots — Right

Dual-channel DDR5, up to 256 GB, rated to 9200+ MT/s (OC) with one single-rank DIMM per channel. Intel XMP 3.0 and CUDIMM supported.

4

PCIe 5.0 x16 slot with Steel Armor II — Upper expansion

Wired to the CPU at PCIe 5.0 x16. EZ PCIe Release frees a long graphics card with one press; an 8-pin PCIe supplemental power header backs the slot.

5

4 × M.2 under M.2 Shield Frozr — Lower half

M.2_1 PCIe 5.0 x4 and M.2_2 PCIe 4.0 x4 from the CPU, M.2_3 and M.2_4 PCIe 4.0 x4 from the chipset (M.2_4 also SATA). EZ M.2 Clip II makes them tool-free.

6

Right-angle SATA and headers — Bottom & right edge

4 × SATA 6Gb/s, a front USB-C 20Gbps header with 27W charging, 3 ARGB V2 and 1 RGB header, and a Thunderbolt 5 add-in card header (card not included).

16+1+1+1 Duet Rail, 90A SPS

Sixteen 90A smart power stages for Vcore plus one each for SA, GT and VNNAON, under digital PWM control, with MSI Core Boost.

6-Layer Server-Grade PCB

Six layers with 2oz thickened copper carry the current and keep DDR5 and PCIe 5.0 signals clean.

Frozr Guard Cooling

Extended, heavy-plated VRM heatsinks on 7W/mK MOSFET pads with extra choke pads, an enlarged chipset heatsink and a double-sided M.2 Shield Frozr.

Combo & EZ Conn Fan Headers

A 3A pump/fan combo header that auto-detects the device, six system fan headers, and the EZ Conn header for MSI EZ fans and MSI liquid coolers.

Technical & Policy Q&A

Common questions about this motherboard
Which processors does it support?+
Intel Core Ultra (Series 2) desktop processors on socket LGA1851. Older 12th–14th Gen Core chips use LGA1700 and will not fit.
What can I do with the two Thunderbolt 4 ports?+
Each rear Thunderbolt 4 USB-C port runs at 40Gbps, supplies 15W, can drive a display over DisplayPort (with a CPU that has integrated graphics) and can daisy-chain up to three Thunderbolt 4 devices. A header also accepts MSI's optional Thunderbolt 5 add-in card, which is sold separately.
How many SSDs can I install?+
Four M.2 NVMe drives plus four SATA drives. M.2_1 runs at PCIe 5.0 x4 and M.2_2 at PCIe 4.0 x4, both from the CPU; M.2_3 and M.2_4 run at PCIe 4.0 x4 from the chipset, and M.2_4 also takes M.2 SATA drives.
Is this the MAG Z890 TOMAHAWK WIFI or the WIFI II?+
This is the original MAG Z890 TOMAHAWK WIFI (board MS-7E32), with two rear Thunderbolt 4 ports and two CPU-connected M.2 slots.
Does AHW Store update the BIOS before shipping?+
Every motherboard ships sealed in its original retail packaging with the factory BIOS. Our engineers can flash the latest vendor BIOS free of charge on request when you order a CPU with the board, which guarantees first-boot compatibility with the newest supported CPU generation.
