This article covers ASRock Intel 第10世代CPU(LGA1200)対応 H470チップセット搭載 ATXマザーボード 【国内正規代理店品】 H470 Steel Legend.
Overview
The ASRock H470 Steel Legend is an ATX motherboard built around the Intel H470 chipset, designed for Intel 10th Gen Core processors (LGA1200 socket). It supports up to 128GB of DDR4 memory across four slots, with speeds reaching 2933MHz. Large heatsinks on the chipset and M.2 slots help maintain stable thermals during extended use. Positioned in the mid-range segment, this motherboard strikes a balance between cost and features for gaming PCs and creative workstations. It offers two PCIe 3.0 x16 slots, four M.2 slots (two supporting PCIe Gen3 x4 & SATA3), and a 2.5GbE LAN port for fast networking. USB 3.2 Gen2 Type-A and Type-C ports provide 10Gbps data transfer speeds. The onboard audio solution uses a Realtek ALC1200 codec with Nichicon Fine Gold audio capacitors, complemented by Nahimic Audio software for sound optimization. ARGB LED headers allow synchronization with compatible lighting components, making it easy to build a visually cohesive system.
Compatibility Guide
This motherboard uses the LGA1200 socket and is compatible exclusively with Intel 10th Gen Core processors (Comet Lake-S). It does not support 11th Gen (Rocket Lake-S) CPUs. Memory support includes four DDR4 DIMM slots with a maximum capacity of 128GB, supporting speeds of 2933/2800/2666/2400/2133 MHz (non-ECC, unbuffered). The form factor is standard ATX (305mm x 244mm), fitting most ATX cases. Power delivery requires a 24-pin main connector and an 8-pin CPU power connector, compatible with standard ATX power supplies. Storage connectivity includes six SATA3 ports and four M.2 slots (two PCIe Gen3 x4 & SATA3, one dedicated for a Wi-Fi key E module). Graphics output options include one HDMI and one DisplayPort, useful when using CPUs with integrated graphics. Note that the H470 chipset does not support CPU overclocking, so K-series processors will run at stock multipliers.
Product Info
The ASRock H470 Steel Legend launched in mid-2020 as a mid-range motherboard option. It sits between Intel's B460 and Z490 chipsets in terms of features and pricing, offering a cost-effective platform for balanced builds. The typical retail price is around ¥9,000, with warranty coverage per ASRock's standard policy (usually 1-3 years). Key specifications include an 11-phase Dr.MOS digital power design for stable voltage delivery, 2.5GbE LAN, USB 3.2 Gen2 ports, and ARGB LED headers. These features make it suitable for entry-level to mid-range PC builds where reliability and expandability are priorities.
Best Use Cases
First, this motherboard is ideal for budget-conscious builders who want a stable Intel 10th Gen platform without paying a premium for Z490 features. It provides sufficient expansion for a gaming PC or office workstation at a lower cost. Second, users who plan to install multiple M.2 SSDs will appreciate the four M.2 slots, two of which support PCIe Gen3 x4 speeds. This allows for fast storage configurations without sacrificing SATA ports. The 2.5GbE LAN is also beneficial for NAS users or those with high-speed internet connections. Third, enthusiasts who enjoy customizing their PC's appearance with ARGB lighting will find the onboard ARGB headers convenient. They can synchronize fans, LED strips, and other compatible components for a unified look.
Things to Consider
The most important limitation is that this motherboard supports only Intel 10th Gen CPUs (Comet Lake-S). It is not compatible with 11th Gen (Rocket Lake-S) processors, so careful CPU selection is required. Additionally, the H470 chipset does not allow CPU overclocking, meaning K-series processors cannot have their multipliers adjusted. Memory overclocking (XMP) is supported, but speeds above 2933MHz depend on the CPU's memory controller. The second PCIe x16 slot operates at x4 speed, which limits dual-GPU configurations. Some M.2 slots may share bandwidth with SATA ports, so check the manual before planning your storage layout. Compared to B460 motherboards, the H470 Steel Legend offers higher memory speed support (2933MHz vs 2666MHz) and more M.2 slots. However, if the price difference is small, a Z490 board might be worth considering for future upgrade flexibility.
