ASRock Z890I Nova WiFi (LGA1851/Intel Z890/Mini-ITX/12+1+1+1+1 110A SPS/Dual Thunderbolt 4) Review
The Z890I Nova WiFi is ASRock's flagship Mini-ITX board for Intel's Core Ultra 200S platform, combining a heavily disclosed VRM spec with three M.2 slots and dual Thunderbolt 4/USB4 ports for high-end compact Intel builds.
A 12+1+1+1+1 phase design using 110A SPS stages for VCore gives this board some of the strongest disclosed power delivery in the Mini-ITX Z890 segment, suited to Core Ultra 9 285K-class chips even under sustained load. Two DDR5 DIMM slots support up to 128GB total capacity, with CUDIMM support enabling speeds up to 9866+ MT/s, among the highest disclosed OC ceilings in this batch. A single PCIe 5.0 x16 slot handles the GPU, and three M.2 slots are provided: one PCIe 5.0 x4 and two PCIe 4.0 x4, giving this board more SSD capacity than most Z890 ITX competitors. A Realtek RTL8126 5Gbps LAN controller pairs with Wi-Fi 7 and Bluetooth 5.4. Two Thunderbolt 4/USB4 ports handle high-speed peripherals and displays, and ASRock's "Memory OC Shield" is marketed as improving memory overclocking stability at these DIMM speeds. Against the Gigabyte Z890I AORUS Ultra in this catalog, the Z890I Nova WiFi offers a third M.2 slot, faster 5Gbps LAN, and a fully disclosed VRM spec, making it the more feature-dense (and likely pricier) of the two Z890 ITX boards.
