This article covers ASRock Intel 第10世代CPU(LGA1200)対応 H470チップセット搭載 Mini-ITXマザーボード 【国内正規代理店品】 H470M-ITX.

Overview

The ASRock H470M-ITX/ac is a Mini-ITX motherboard designed for Intel's 10th Gen Core processors (LGA1200). Despite its compact 170mm x 170mm footprint, it packs two DDR4 memory slots, three M.2 slots (one pre-populated with a Wi-Fi module), and a solid set of connectivity options including 2.5GbE LAN and 802.11ac Wi-Fi. Powered by the Intel H470 chipset, this board skips overclocking support but delivers stable, reliable performance for everyday computing. The 7-phase Dr.MOS VRM, Realtek ALC1200 audio codec with Nahimic Audio, and Nichicon Fine Gold audio capacitors ensure a quality experience for both work and entertainment. Positioned as an entry-to-mid-range solution, the H470M-ITX/ac is ideal for users building a compact desktop, home server, or HTPC. Its reasonable price point and well-rounded feature set make it a strong contender in the Mini-ITX motherboard market.

Compatibility Guide

CPU Socket: LGA1200, compatible with Intel 10th Gen Core i9/i7/i5/i3, Pentium Gold, and Celeron processors. Note: 11th Gen (Rocket Lake) CPUs are not supported. Memory: 2 x DDR4 DIMM slots, supporting DDR4-2933/2800/2666/2400/2133 non-ECC, unbuffered memory. Maximum capacity is 32GB (16GB per slot). Form Factor: Mini-ITX (170mm x 170mm). Fits only Mini-ITX cases; not compatible with ATX or Micro-ATX cases. Expansion: 1 x PCIe 3.0 x16 slot for a graphics card or other add-in card. Storage: 4 x SATA3 ports, 2 x M.2 slots for storage (one PCIe Gen3 x4 only, one PCIe Gen3 x4 & SATA3), plus 1 x M.2 Key E slot for the pre-installed Wi-Fi module. Power: 24-pin ATX main connector and 8-pin CPU power connector. An SFX power supply is recommended for Mini-ITX builds.

Product Info

Released in mid-2020, the ASRock H470M-ITX/ac is an entry-to-mid-range Mini-ITX motherboard. It omits overclocking features but compensates with a well-balanced selection of I/O and expansion options for its size. Key specifications include a 7-phase Dr.MOS VRM, Realtek ALC1200 audio with Nahimic Audio suite, and Nichicon Fine Gold audio capacitors. Video output is handled by one HDMI and one DisplayPort port, leveraging the integrated graphics of 10th Gen CPUs. The board carries a standard 1-year warranty (for official domestic distribution units in Japan). It is available through and major PC component retailers, with a street price around ¥22,800.

Best Use Cases

Compact Home Server or NAS Builder: With three M.2 slots and four SATA ports, you can pack plenty of storage into a tiny chassis. Pair it with a low-power 10th Gen Core i3 or Pentium for an energy-efficient 24/7 server. Space-Saving Office / HTPC: The H470M-ITX/ac is perfect for a quiet, small-form-factor PC for web browsing, office applications, and media playback. Integrated graphics handle 4K video output without a dedicated GPU. Budget-Conscious First-Time Builder: Beginners will appreciate the straightforward BIOS and lack of overclocking complexity. However, the limited expansion slots mean you must plan your build carefully. Not ideal for: Gamers seeking high frame rates (you'll need a discrete GPU, which uses the only PCIe slot), users wanting multiple GPUs or capture cards, or anyone planning to use an 11th Gen CPU.

Things to Consider

No 11th Gen CPU support: Despite sharing the LGA1200 socket, the H470 chipset only works with 10th Gen (Comet Lake) processors. If you have a Rocket Lake CPU, look for a B560 or Z490 board instead. Single PCIe slot: You get exactly one PCIe 3.0 x16 slot. If you install a graphics card, you cannot add a Wi-Fi card (though Wi-Fi is built-in), a capture card, or any other PCIe device. M.2 configuration quirks: One of the storage M.2 slots supports both PCIe and SATA modes, which may require a BIOS setting change depending on your SSD type. Memory speed cap: XMP (memory overclocking) is not supported. Even if you install high-speed DDR4-3600 RAM, it will run at a maximum of 2933 MHz. * Competition: Alternatives like the ASUS ROG STRIX B460-I GAMING or GIGABYTE B460I AORUS PRO offer similar features, but the ASRock stands out with its built-in 2.5GbE LAN and Wi-Fi module. ## FAQ
Q: Can I use a Core i7-10700K with this motherboard? A: Yes, the i7-10700K is compatible. However, since the H470 chipset does not support overclocking, the CPU will run at stock speeds only. The 'K' suffix is essentially wasted on this board. Q: How many M.2 SSDs can I install? A: You can install up to two M.2 SSDs for storage (one PCIe-only, one PCIe/SATA combo). There is also a third M.2 slot (Key E) that is occupied by the pre-installed Wi-Fi module. Q: Is this motherboard good for gaming? A: For light or older games, the integrated GPU in a 10th Gen CPU may suffice. For modern 3D gaming, you will need to add a discrete graphics card in the single PCIe slot. Keep in mind that doing so will prevent you from using any other PCI
