This article covers ASUS Intel Z390 搭載 LGA1151対応 マザーボード ブラック ROG MAXIMUS XI HERO (WI-FI AC) 【ATX】.

Overview

The ASUS ROG MAXIMUS XI HERO (WI-FI AC) is an ATX gaming motherboard built around the Intel Z390 chipset. It supports LGA1151 sockets for 8th and 9th Gen Intel Core processors, and offers DDR4 memory up to 64GB with overclocking support beyond 4400MHz. Key features include dual M.2 slots with heatsinks, SupremeFX audio, Intel Gigabit LAN, onboard 802.11ac Wi-Fi, and Aura Sync RGB lighting. This motherboard targets enthusiasts and gamers who want a high-quality foundation for a flagship gaming PC. The ROG lineup is known for robust VRM design, premium components, and extensive tuning options in the UEFI BIOS. With integrated Wi-Fi and Bluetooth 5.0, it also suits users who prefer a clean, cable-free network setup.

Compatibility Guide

The LGA1151 socket is compatible with Intel 8th Gen (Coffee Lake) and 9th Gen (Coffee Lake Refresh) processors, including Core i9, i7, i5, i3, Pentium Gold, and Celeron. Memory support covers DDR4 DIMMs across four slots, with official support up to DDR4-4400 (OC) and a maximum capacity of 64GB. XMP profiles are fully supported. Expansion slots include two PCIe 3.0 x16 (first runs at x16, second at x4) and three PCIe 3.0 x1. Storage options consist of six SATA 6Gb/s ports and two M.2 slots (both support PCIe 3.0 x4 and SATA modes). The M.2 heatsinks help keep NVMe SSDs cool under load. The board follows the standard ATX form factor (30.5cm x 24.4cm) and fits most ATX cases. Power delivery uses a 24-pin ATX main connector and one 8-pin EPS12V CPU power. Rear I/O includes USB 3.1 Gen2 Type-A (2), Type-C (1), USB 3.1 Gen1 (4), USB 2.0 (2), plus HDMI and DisplayPort outputs for integrated graphics.

Product Info

Released in October 2018, the ASUS ROG MAXIMUS XI HERO (WI-FI AC) sits in the high-end tier of Z390 motherboards. It features a 10-phase VRM design, premium capacitors, and a comprehensive cooling solution including a chipset heatsink and M.2 heatsinks. The warranty period is typically three years (varies by region). Key specifications: Intel Z390 chipset, LGA1151 socket, 4x DDR4 DIMM slots (max 64GB, OC 4400+ MHz), 2x PCIe 3.0 x16, 3x PCIe 3.0 x1, 2x M.2 (PCIe 3.0 x4 & SATA), 6x SATA 6Gb/s, Intel Gigabit LAN, 802.11ac Wi-Fi, Bluetooth 5.0, SupremeFX S1220A audio, Aura Sync RGB headers.

Best Use Cases

High-end gaming: Pair with a Core i9-9900K or i7-9700K for maximum gaming performance. The robust VRM and cooling allow stable overclocking, and the onboard Wi-Fi eliminates the need for a separate adapter. Overclocking enthusiasts: The UEFI BIOS offers granular voltage and frequency controls, plus automated tuning via 5-Way Optimization. The board's thermal design handles high CPU and memory overclocks well. RGB-focused builds: Aura Sync lets you synchronize lighting across compatible components (fans, RAM, GPU). The board includes both standard RGB and addressable RGB headers. Content creation: Dual M.2 slots support fast NVMe SSDs for video editing and 3D rendering. However, lack of Thunderbolt may limit external high-speed storage options.

Things to Consider

This motherboard uses the Z390 chipset, which is limited to LGA1151 processors (8th/9th Gen). Upgrading to newer Intel CPUs (10th Gen or later) requires a board replacement. PCIe 3.0 is the maximum supported; while PCIe 4.0/5.0 GPUs will work, they will run at PCIe 3.0 speeds, which has negligible real-world impact for most games. One M.2 slot shares bandwidth with certain SATA ports, so check the manual when populating drives. The second PCIe x16 slot runs at x4 mode and also shares lanes with SATA ports, limiting multi-GPU or expansion card configurations. Given its age, the price has dropped significantly from launch. Compare with newer Z590 or Z690 boards if you need PCIe 4.0/5.0, Thunderbolt, or Wi-Fi 6E. For a budget-conscious builder, this board still offers excellent value for a high-end LGA1151 system. ## FAQ
Q: Can I use an Intel Core i7-9700K with this motherboard? A: Yes, the i7-9700K (LGA1151, 9th Gen) is fully supported out of the box. No BIOS update is required. Q: Will DDR4-3600 memory work? A: Officially supported up to DDR4-4400 (OC), so DDR4-3600 should work with XMP enabled. However, always check the QVL list for your specific memory kit to ensure compatibility. Q: Can I install Windows 11 on this motherboard? A: Yes, the board includes TPM 2.0 (firmware-based) and UEFI support, meeting Windows 11 requirements. Run Microsoft's PC Health Check tool to confirm compatibility before upgrading.
