This article covers ASUS AMD X470 搭載 マザーボード Socket AM4対応 PRIME X470-PRO 【ATX】.

Overview

The ASUS PRIME X470-PRO is an ATX motherboard built around the AMD X470 chipset, supporting Socket AM4 processors including Ryzen 2nd Gen (Pinnacle Ridge), 1st Gen, and Ryzen APUs with Radeon Vega Graphics. It packs four DDR4 DIMM slots rated up to 3466 MHz (OC), dual M.2 slots, and USB 3.1 Gen2 connectivity, making it a solid mid-range foundation for a cost-conscious build. Priced at around ¥11,000 (~$75), this board offers exceptional value for budget builders who need a reliable platform with Aura Sync RGB, Fan Xpert 4, and a comprehensive UEFI. The PRIME series is known for its emphasis on stability and noise control rather than flashy aesthetics, and the X470-PRO carries that tradition forward. However, it's important to note that the X470 chipset was released in 2018 and does not officially support Ryzen 3000/5000 series CPUs. While some users have reported success with beta BIOS, ASUS does not list these processors as compatible. The chipset also lacks PCIe 4.0 support, which may be a dealbreaker for users wanting the fastest SSDs or next-gen GPUs.

Product Info

The ASUS PRIME X470-PRO launched in April 2018 with an MSRP around ¥16,000; current street price is approximately ¥11,000. The board comes with a 3-year manufacturer warranty. It sits in the mid-range segment of AMD motherboards from that era, above B450 but below X470 flagship models. Market positioning: it is an entry-level-to-mid-range board, ideal for pairing with a Ryzen 5 2600 or 2400G for a balanced, affordable desktop. If you need PCIe 4.0 or official support for Ryzen 5000, you should look at B550 or X570 boards. The X470-PRO stands out for its combination of features (dual M.2, Aura Sync, robust VRM) at a very attractive price point for last-gen builds.

Best Use Cases

  • Budget-First DIY Builders: If you're building a secondary PC, a media server, or a first gaming rig on a tight budget, pairing this board with a used Ryzen 5 2600 and a GTX 1660 Super yields solid 1080p performance for under $400 total. - Silence-Optimized Office/Media PC: The fan control software (Fan Xpert 4) and passive chipset cooling help keep noise low. Combine with a quiet case and an aftermarket CPU cooler for near-silent operation. - RGB Enthusiasts on a Budget: The integrated Aura Sync header and onboard LED let you synchronize RGB strips and fans without extra controllers. A cheap way to get into ASUS's ecosystem. - Who Should NOT Buy: Those wanting official Ryzen 5000 support, PCIe 4.0, more than 64 GB RAM, or multiple GPU configurations. Also, if you plan to upgrade to a high-end GPU soon, consider a newer platform.

Things to Consider

The biggest limitation is the lack of official support for Ryzen 3000/5000 CPUs. While some BIOS mods exist, they are unsupported and may introduce instability. Additionally, the X470 chipset is limited to PCIe 3.0, so modern Gen4 SSDs will not run at full speed. Memory capacity maxes out at 64 GB—no 128 GB option. Compared to a B450 board, the X470-PRO offers slightly better VRM cooling and more USB ports, but B450 boards are generally cheaper and similar in features. For a similar price, a B550 board (e.g., ASUS TUF B550-PLUS) provides PCIe 4.0 and official Ryzen 5000 support, making the X470-PRO a niche choice for bargain hunters with older CPUs. Also ensure your CPU cooler has an AM4 mounting bracket. Coolers designed for AM3+ sockets may not work out of the box. ## FAQ
Q: Can I use a Ryzen 5 5600X on this motherboard? A: Officially no. While some beta BIOS versions may boot a 5600X, ASUS does not provide validated support. For guaranteed compatibility, step up to a B550 or X570 board. Q: Does the second M.2 slot support NVMe? A: Yes, both M.2 slots support PCIe 3.0 x4 NVMe drives. The first slot (M.2_1) also supports SATA mode and includes a heatsink. The second slot (M.2_2) is PCIe-only. Q: What is the maximum RAM speed I should expect? A: With a Ryzen 2nd Gen CPU, DDR4-3200 is typically stable after enabling DOCP/XMP. The official spec lists up to 3466 MHz but that depends heavily on your CPU's memory controller.
