ASUS ROG Maximus Z890 Hero

ASUS's flagship LGA1851 board sits in the no-compromise tier with a 22+2+1+2 power stage array, six M.2 slots (three Gen5), WiFi 7, dual 5G+2.5G LAN, and Thunderbolt 4 — a kitchen-sink spec sheet for Core Ultra 200S builds that lean on storage and connectivity. It's overkill for gaming, where a far cheaper Z890 or B860 board performs identically. Buy it for heavy multi-M.2 workstations or showcase builds; skip it if you're gaming-first on a budget.

Verdict

Best for

  • Flagship-tier LGA1851: 22+2+1+2 stages, 6x M.2 (3x Gen5), WiFi 7, 5G+2.5G LAN, Thunderbolt 4

Who should skip this

  • Anyone gaming-first on a budget — a budget Z890/B860 board games identically

Known limitations

  • $699 launch MSRP; deep mid-2026 discounting (Newegg first-party $429.99) reflects slow Arrow Lake demand

Compatibility

Built around ATX, DDR5, Intel LGA1851, PCIe 5.0. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →
