This article covers ASUS Prime Z890M-PLUS WiFi Z890 LGA 1851 mATX マザーボード.

Overview

The ASUS Prime Z890M-PLUS WiFi is a micro-ATX motherboard built around Intel's Z890 chipset and the LGA1851 socket, designed for the latest Core Ultra Series 2 processors. It packs modern connectivity including DDR5 memory support, a PCIe 5.0 x16 slot, three M.2 slots, Wi-Fi 7, and 2.5Gb Ethernet into a compact footprint. A 10+1+2+1 phase 80A DrMOS VRM ensures stable power delivery even under sustained loads, making it suitable for mid-range to high-end Core Ultra CPUs. ASUS also includes AI Cooling II and AI Networking II for intelligent system optimization, plus a suite of DIY-friendly features like BIOS FlashBack, Q-LED Core, and a pre-mounted I/O shield. At roughly ¥35,000 (around $230 USD), the Prime Z890M-PLUS WiFi sits firmly in the mid-range tier, offering excellent value for builders who want a feature-rich mATX platform without stepping up to premium ROG models.

Compatibility Guide

The motherboard uses the LGA1851 socket exclusively for Intel Core Ultra (Series 2) processors. It supports dual-channel DDR5 memory up to 192GB, with official speeds up to DDR5-7200 (OC). The mATX form factor (244×244 mm) fits most mATX cases. Expansion slots include one PCIe 5.0 x16 (CPU-attached), one PCIe 4.0 x16 (x4 electrical), and three M.2 slots: one PCIe 5.0 x4 (CPU) and two PCIe 4.0 x4 (chipset). There are also four SATA 6Gbps ports. Power is supplied via a 24-pin main connector and an 8-pin EPS12V; a 650W or higher PSU is recommended for typical configurations with a discrete GPU.

Product Info

The ASUS Prime Z890M-PLUS WiFi launched in October 2024 with a street price around ¥35,000 (approximately $230). It carries a standard 3-year warranty (registration required). The Z890 chipset provides CPU-attached PCIe 5.0, Thunderbolt 4 header support (via USB4), and ample connectivity for both gaming and productivity builds. Its market positioning is upper mid-range: not the flashiest, but well-equipped for most users.

Best Use Cases

Compact gaming PC builders Pair it with a Core Ultra 5 or 7 and a PCIe 5.0 GPU like the RTX 5060 Ti for a high-refresh-rate 1440p gaming rig. The mATX size allows for smaller cases without sacrificing performance. Content creators on a budget DDR5 memory and fast NVMe storage (including a PCIe 5.0 slot) are ideal for video editing and 3D rendering. Thunderbolt 4 header support enables high-speed external storage or a dock. * First-time PC builders BIOS FlashBack lets you update the BIOS without a CPU installed, and the Q-LED Core simplifies troubleshooting. The layout is clean and easy to work with. However, if you need many PCIe expansion cards (e.g., multiple capture cards) or plan heavy overclocking on a Core Ultra 9, a full-ATX board with more robust VRM may be a better choice.

Things to Consider

The mATX form factor means PCIe slot spacing is tight; a thick dual-slot GPU may block the second x16 slot. While the VRM is adequate for stock operation, pushing a Core Ultra 9 under extended all-core loads might benefit from better airflow over the VRM heatsinks. LGA1851 is a new socket—there is no backward compatibility with LGA1700 CPUs. Ensure you purchase a Core Ultra Series 2 processor. The board lacks a POST code display, relying on Q-LED Core (4 LEDs) for debugging, which is less granular than a numeric display. Compared to ASUS's TUF Gaming Z890-PLUS WiFi (ATX), the Prime model skips some premium features like additional M.2 heatsinks and a more aggressive VRM layout, but it costs less and fits smaller cases. ## FAQ
Q: Is this motherboard compatible with Intel Core i7-14700K? A: No. The LGA1851 socket only supports Intel Core Ultra Series 2 processors. 13th/14th Gen LGA1700 CPUs will not fit. Q: Can I use a PCIe 5.0 graphics card? A: Yes, the primary x16 slot runs at PCIe 5.0 speeds, supporting GeForce RTX 50-series and Radeon RX 9000-series cards. Q: Does it support DDR5-7200 overclocking? A: The official spec lists DDR5-7200 (OC). Actual stability depends on your CPU's IMC and memory kit. Enabling XMP is recommended for rated speeds. Q: Does the box include a Wi-Fi antenna? A: Yes, the ASUS WiFi Q-Antenna (external desktop antenna) is included in the package.
