GIGABYTE Z890 A TACHYON D X E Intel motherboard

LGA 1851 Intel Z890 EATX motherboard

The GIGABYTE Z890 A TACHYON D X E is an EATX motherboard built on the Intel Z890 chipset for Core Ultra Series 2 processors in the LGA 1851 socket. It targets enthusiasts and overclockers who want a high-phase power design and extensive high-speed expansion in a dual-channel DDR5 platform.

Verify EATX clearance and two-slot memory plan

Confirm your chassis accepts an EATX form factor before ordering, as this board exceeds standard ATX dimensions. The board provides only two 288-pin DDR5 slots supporting up to 256 GB total, so choose a matched 2-module kit rather than a four-module kit. Ensure your power supply delivers enough 12 V current for the 18+1+2 phase VRM under heavy loads.

Screwless M.2 shields and front-panel Thunderbolt 4

Four M.2 slots include tool-free heatsink clips that speed up SSD installation and removal without losing tiny screws. A front-panel Thunderbolt 4 header lets compatible cases expose a 40 Gb/s Type-C port for external storage or docks. The 5 GbE LAN and WiFi7 with directional antenna improve wired and wireless throughput for large transfers.
