This article covers ASRock マザーボード Z890I Nova WiFi Intel CPU Core Ultra (LGA1851) 対応 Z890 チップセット DDR5 Mini-ITX マザーボード 【国内正規代理店品】.

Overview

ASRock Z890I Nova WiFi is a Mini-ITX motherboard built around the Intel Z890 chipset, designed for Intel Core Ultra processors (LGA1851). It supports up to 128GB of DDR5 memory with overclocking speeds reaching 9466 MHz, making it one of the most feature-rich small-form-factor boards on the market. This motherboard targets enthusiasts who want a compact yet powerful system. With PCIe 5.0 support, Wi-Fi 7, and robust power delivery, it can handle everything from high-refresh-rate gaming to content creation workloads, all within a tiny 170mm x 170mm footprint. Key specs include an LGA1851 socket, dual DDR5 DIMM slots (max 128GB), one PCIe 5.0 x16 slot, dual M.2 slots (PCIe 5.0 + PCIe 4.0), and four SATA3 ports. It ships with integrated Wi-Fi 7 and Bluetooth 5.4.

Compatibility Guide

Socket: LGA1851 exclusively for Intel Core Ultra (Arrow Lake / Lunar Lake). Some LGA1700 coolers may work but check ASRock's official cooler compatibility list. Memory: 2x DDR5 DIMM slots, dual-channel, up to 128GB (non-ECC). Supports XMP and EXPO profiles for speeds up to 9466 MHz+. Form Factor: Mini-ITX (170mm x 170mm). Fits any case designed for Mini-ITX, including compact SFF cases. Power: 24-pin ATX + 8-pin CPU EPS. Recommended PSU wattage: 650W or higher for a typical build with a discrete GPU. Storage: 1x M.2 PCIe 5.0 x4 + 1x M.2 PCIe 4.0 x4, plus 4x SATA3 ports. Great mix of high-speed NVMe and traditional HDDs. Graphics: Single PCIe 5.0 x16 slot. Fits modern GPUs easily, but the compact layout may interfere with thick cards in some cases.

Product Info

Released in late 2025, the ASRock Z890I Nova WiFi sits in the high-end Mini-ITX segment. It combines the latest Z890 chipset with premium features like 9466 MHz memory support, PCIe 5.0, and built-in Wi-Fi 7. Pricing is around $300–$350, reflecting its niche status. The motherboard comes with a 3-year warranty through ASRock's official distributor in Japan.

Best Use Cases

Compact Gaming PC: Ideal for building a small yet powerful gaming rig with a Core Ultra processor and a high-end GPU. The Z890 chipset allows CPU and memory overclocking for extra FPS. Not recommended for users who need multiple PCIe expansion slots or traditional ATX boards. Space-Saving Workstation: Professionals working with video editing, 3D modeling, or software compilation benefit from 128GB memory capacity and PCIe 5.0 storage speeds. The small footprint fits neatly on a desk without dominating the workspace. * Home Theater / Living Room PC: With integrated Wi-Fi 7 and Bluetooth, it's easy to build a silent, media-focused system that can also game or run light creative tasks. If you need four memory slots for maximum capacity, consider an ATX board instead.

Things to Consider

Expansion Limits: Only one PCIe x16 slot and two memory slots. Adding a large GPU can block access to the M.2 slot or impede airflow in tight cases. Cooler Compatibility: While LGA1851 is physically the same as LGA1700, some coolers may require a new mounting kit. Always verify with ASRock's official list. Overclocking Realism: The 9466 MHz memory capability is impressive but requires good CPU silicon, high-end memory kit, and proper cooling. It's more a goal for experienced overclockers than a plug-and-play feature. Price Premium: Mini-ITX boards cost more than their ATX counterparts. If you don't need the smallest footprint, a Z890 ATX board offers better value. ## FAQ
Q: Can I use a Core Ultra 7 265KF on this board? A: Yes, any LGA1851 Intel Core Ultra processor (including the Core Ultra 7 265KF) is supported. Make sure the BIOS is updated to the latest version for optimal stability. Q: Does it support DDR5-6000 memory out of the box? A: Yes. Standard JEDEC DDR5-6000 kits will work at their rated speed. For XMP or EXPO overclocking, check the board's memory QVL for best compatibility. Q: Will an RTX 4080 fit in a typical Mini-ITX case with this motherboard? A: The PCIe slot can handle the card electrically, but physical clearance depends on the case. Measure maximum GPU length and thickness allowed by your case before purchasing.
