Built for Intel Core Ultra Series 2

The ASRock Z890 Steel Legend WiFi is an ATX motherboard using the LGA 1851 socket and Intel Z890 chipset. It targets daily users and mainstream enthusiasts who want a durable platform for current Intel Core Ultra processors. The board delivers an 18+1+1+1+1 power phase design with 80A SPS stages for stable CPU delivery.

Verify socket and memory before ordering

Your processor must be an Intel Core Ultra Series 2 CPU that fits LGA 1851. The board provides four 288-pin DDR5 slots supporting dual-channel operation up to 256 GB total. Native speeds run to 5600 MHz; XMP 3.0 profiles reach 9066+ MHz (OC). Graphics output uses one HDMI port and one Thunderbolt 4 Type-C connector.

Replaces Z790 or older Intel platforms

Moving from a Z790 board adds the LGA 1851 socket, PCIe 5.0 on the primary x16 slot, and a CPU-attached M.2 Gen5 x4 drive running at 128 Gb/s. The VRM upgrades to 20K-hour 1000 µF capacitors and 80A SPS stages. The jump is worth it when you need Gen5 GPU bandwidth, faster NVMe throughput, or the new Core Ultra architecture.

Questions about this item

Does the board ship with any cables, brackets or driver media, or must I source them separately?

The box contains the motherboard, I/O shield, SATA cables, M.2 screws, Wi‑Fi antennas, RGB cable, quick guide and driver disc; no extra mounting hardware or cables are required for a standard build.

Which DDR5 speed should I pick if I want the highest native frequency without overclocking?

The board runs DDR5‑5600 natively with a single rank per channel; higher speeds up to 9466 MHz are only reached through XMP 3.0 overclocking profiles.

What does the 128 Gb/s M.2 slot actually deliver for a Gen5 NVMe drive?

The CPU‑linked M2_1 slot provides a PCIe 5.0 x4 link rated at 128 Gb/s, giving a Gen5 NVMe SSD its full interface bandwidth.
