This article covers ASRock マザーボード X870 Pro RS WiFi AMD Ryzen 9000 シリーズ CPU (Soket AM5) 対応 X870 チップセット ATX マザーボード 【国内正規代理店品】.

Overview

The ASRock X870 Pro RS WiFi is an ATX motherboard built around the AMD X870 chipset, supporting Socket AM5 for Ryzen 9000, 8000, and 7000 series processors. Its white PCB and heatsinks make it a natural fit for light-themed PC builds, while the 14+2+1 phase power delivery with 80A Dr.MOS handles even the most demanding Ryzen 9 CPUs with ease.
Memory support extends to DDR5-8000+ (OC) across four DIMM slots, with a maximum capacity of 256GB. The board also features a single PCIe 5.0 x16 slot for the latest graphics cards, plus three M.2 slots—one of which runs at PCIe 5.0 x4 for blazing-fast NVMe storage.
Connectivity is a standout: two USB4 Type-C ports on the rear I/O, Wi-Fi 7, and a 2.5GbE LAN port. This makes the X870 Pro RS WiFi a well-rounded choice for users who want a modern feature set without stepping up to the flagship X870E platform.

Compatibility Guide

Socket AM5 is the only socket option, compatible with all Ryzen 7000, 8000, and 9000 series CPUs. The motherboard supports DDR5 memory only, with ECC and non-ECC DIMMs. XMP and EXPO profiles are supported for easy overclocking.
Form factor is standard ATX (305×244 mm). Most mid-tower and full-tower cases will accommodate it. Power delivery requires a 24-pin ATX main connector and two 8-pin EPS12V connectors for the CPU. Ensure your power supply has sufficient EPS cables, especially if you plan to overclock a high-core-count CPU.
Storage options include four SATA 3.0 ports and three M.2 slots: one Blazing M.2 (PCIe 5.0 x4), one Hyper M.2 (PCIe 4.0 x4), and one Ultra M.2 (PCIe 3.0 x4 & SATA3). All M.2 slots come with pre-installed heatsinks, which is crucial for PCIe 5.0 SSDs that can run hot.

Product Info

Released in September 2024, the ASRock X870 Pro RS WiFi sits in the mid-to-upper-mid-range segment. Priced around ¥30,000 in Japan, it competes with B650E boards but adds USB4 and Wi-Fi 7 as standard. The X870 chipset is essentially a B650E with mandatory USB4 support, so this board offers a clean upgrade path for Ryzen 9000 users.
Warranty is one year from the authorized Japanese distributor. ASRock also offers a product registration program that may extend the warranty period—check their official site for details.

Best Use Cases

First, the white aesthetic is a major draw for builders who want a cohesive color scheme. Pair it with white RAM, GPU, and case fans for a clean, modern look. The board’s white heatsinks and PCB ensure no dark spots ruin the theme.
Second, it’s ideal for mainstream gaming and content creation with a Ryzen 7 or Ryzen 9 CPU. The 14+2+1 phase VRM can handle sustained loads, and the PCIe 5.0 slot will accommodate future high-end GPUs without bottlenecking.
Third, users who need fast storage and external connectivity will appreciate the PCIe 5.0 M.2 slot and USB4 ports. USB4 offers 40 Gbps bandwidth, making it easy to connect high-speed external SSDs or a single-cable docking station.
On the other hand, this board is not for budget-conscious builders who only need basic features. Cheaper B650 or A620 boards will suffice for Ryzen 5 or Ryzen 7 builds without the need for USB4 or Wi-Fi 7. Also, mini-ITX enthusiasts should look elsewhere, as this is a full-size ATX board.

Things to Consider

The most notable limitation is the single PCIe x1 slot. If you plan to install multiple expansion cards (e.g., a capture card, sound card, or additional USB controller), the bottom PCIe 4.0 x16 slot may be blocked by a thick GPU. The second PCIe x16 slot runs at x4 mode electrically, so it’s best used for a storage controller or a second GPU running at reduced bandwidth.
Another point: the Ultra M.2 slot is PCIe 3.0 x4 only, which is slower than the other two. If you have multiple high-end NVMe drives, you’ll want to prioritize the Blazing and Hyper slots.
Compared to B650E boards, the X870 Pro RS WiFi commands a small premium for USB4. If you don’t need USB4, a B650E board with similar VRM and Wi-Fi 7 might be a better value. However, USB4 is increasingly common in external peripherals, so it may be future-proofing worth the extra cost.

FAQ

Q: Can I use this motherboard with a Ryzen 5 7600?
A: Absolutely. The Ryzen 5 7600 is a 65W CPU, and the 14+2+1 phase VRM will run it with ease. You won’t need to worry about power delivery at all.
Q: What memory should I buy?
A: Any DDR5 DIMM kit will work, but for best performance look for kits rated at 6000MT/s or higher with CL30 or lower timings. Both XMP and EXPO profiles are supported, so enable them in the BIOS for full speed.
Q: Is the white color consistent with other white components?
A: ASRock’s white is a matte off-white, slightly warmer than pure white. It pairs well with most white components, but it’s a good idea to check real-world build photos before committing to a full white theme.
