The MEG Z890 Ace is MSI's enthusiast Z890 ATX board, with a 10GbE Marvell LAN port, Wi-Fi 7, two Thunderbolt 4 ports, five M.2 slots and eleven rear USB 10Gbps Type-A ports. A second Gen5 M.2 slot is available by changing a BIOS setting. It suits high-end Core Ultra 9 builds that want 10GbE and many USB ports; MSI lists its pages as showing different VRM figures by region, so verify the exact variant.
