Overview

The ASRock Z890 Nova WiFi is an ATX motherboard built around the Intel Z890 chipset, designed for Intel Core Ultra processors (LGA1851 socket). It supports DDR5 memory up to 256GB and features PCIe 5.0 slots for both graphics and storage, making it a solid foundation for high-end gaming or creative workstations. Positioned in the mid-to-high range of ASRock's lineup, the Z890 Nova WiFi strikes a balance between premium features and reasonable pricing. It includes onboard Wi-Fi 7, 2.5GbE LAN, and a generous selection of USB ports, including a front-panel USB 3.2 Gen2x2 Type-C. The board's build quality is reassuring, with reinforced PCIe slots and substantial heatsinks. For users building a new system around Intel's latest Core Ultra architecture, this motherboard offers a well-rounded feature set without the premium price tag of flagship models. It's a practical choice for enthusiasts who want PCIe 5.0 support and robust connectivity.

Compatibility Guide

CPU Socket: LGA1851 — exclusively for Intel Core Ultra (Arrow Lake) processors. Not compatible with LGA1700 or earlier sockets. Memory: DDR5 only, 4 slots, up to 256GB. Supports XMP and EXPO profiles for overclocking. Form Factor: Standard ATX (305mm x 244mm). Fits most mid-tower and full-tower cases. Expansion Slots: 1x PCIe 5.0 x16 (full bandwidth), 1x PCIe 4.0 x16 (x4 electrical). Multi-GPU possible but second slot is bandwidth-limited. Storage: 2x M.2 PCIe 5.0 x4, 2x M.2 PCIe 4.0 x4, 4x SATA 6Gb/s. Mix NVMe and SATA drives freely. Power: 24-pin main, 8+4 pin CPU. For high-end builds (Core Ultra 9 + RTX 4090), an 850W or higher PSU is recommended.

Product Info

The ASRock Z890 Nova WiFi launched in late 2024 as part of the Z890 chipset lineup. It sits in the mid-to-high tier, offering most premium features (PCIe 5.0, Wi-Fi 7, high-speed USB) at a more accessible price than flagship models. Warranty is standard 3 years for official Japanese imports. Street price is around ¥29,000–¥30,000. Key specs: Intel Z890 chipset, LGA1851 socket, DDR5-9200 (OC) support, ATX form factor. Onboard features include Wi-Fi 7 (BE200), Bluetooth 5.4, 2.5GbE LAN (Realtek), USB 3.2 Gen2x2 Type-C front header, and Realtek ALC1220 audio.

Best Use Cases

High-End Gaming: Pair with a Core Ultra 9 285K and RTX 5090 for 4K high-refresh gaming. PCIe 5.0 ensures future GPU and SSD compatibility. Not ideal for budget gamers — a B760 board would save money. Content Creation: Large DDR5 capacity (up to 256GB) and fast PCIe 5.0 storage accelerate video editing and 3D rendering. Multi-GPU support is useful for GPU rendering workflows. Enthusiast Builds: Users who want the latest platform features (Wi-Fi 7, PCIe 5.0) without paying flagship prices. Good for those planning to keep the system for 3–4 years. Not for: Users on a tight budget, those reusing DDR4 memory, or anyone building a basic office PC — a cheaper chipset like B760 would suffice.

Things to Consider

CPU Upgrade Path: LGA1851 is a new socket with uncertain future CPU support. Don't expect to drop in a next-gen CPU years later. DDR5 Cost: DDR5 memory is still pricier than DDR4, increasing total build cost. Second PCIe Slot Limitation: The second x16 slot runs at x4, so dual-GPU setups will see reduced performance on the second card. Price vs. B760: At ~¥30,000, this board costs nearly double a decent B760 board. Only worth it if you need Z890 features (overclocking, more PCIe lanes, Wi-Fi 7). * BIOS Updates: Early units may require a BIOS update for optimal stability with new Core Ultra CPUs. Check the ASRock support page after purchase. ## FAQ
Q: Can I use a Core Ultra 7 265K with this motherboard? A: Yes, the Z890 Nova WiFi fully supports all Core Ultra processors. The 265K is a great match for this board. Q: Does it support PCIe 5.0 SSDs? A: Yes, two M.2 slots support PCIe 5.0 x4. Use a heatsink-equipped SSD or the included M.2 heatsink to prevent thermal throttling. Q: Can I install DDR4 memory? A: No, DDR4 is physically incompatible. Only DDR5 DIMMs will fit. Make sure to buy DDR5 RAM for this board.
