This article covers MSI X870E Gaming Plus WiFiマザーボード.

Overview

The MSI X870E Gaming Plus WiFi is an ATX motherboard built around AMD's flagship X870E chipset, designed for the AM5 socket. It supports Ryzen 9000, 8000, and 7000 series processors, making it a versatile choice for both new builds and upgrades. The board features a 14-duet rail 60A SPS VRM configuration, ensuring stable power delivery for even the most demanding Ryzen 9000 CPUs.
Memory support extends to DDR5 with overclocking headroom up to 8200+ MT/s in 1DPC 1R configurations. The single PCIe 5.0 x16 slot delivers up to 128GB/s of bandwidth for the latest graphics cards, while storage options include one M.2 Gen5 x4 slot and two M.2 Gen4 x4 slots. Connectivity is a strong suit here, with Wi-Fi 7, Bluetooth 5.4, and a Realtek 5G LAN controller built in.
The rear I/O panel includes a USB4 Type-C port with 40Gbps throughput and display output support, adding to the board's versatility. Positioned in the mid-to-high tier of X870E offerings, this motherboard strikes a balance between premium features and reasonable pricing, making it an attractive option for gamers and content creators alike.

Compatibility Guide

The MSI X870E Gaming Plus WiFi uses the Socket AM5, compatible with AMD Ryzen 9000, 8000, and 7000 series desktop processors. This includes popular gaming CPUs like the Ryzen 7 9800X3D and high-core-count options like the Ryzen 9 9950X3D. Memory is DDR5-only; DDR4 modules are physically incompatible, so plan your memory purchase accordingly. Four DIMM slots support up to 192GB of RAM.
The ATX form factor fits standard mid-tower cases without issue. The primary PCIe 5.0 x16 slot is ready for the latest graphics cards, while the M.2 slots provide flexible NVMe storage options. SATA 6Gbps ports are also available for traditional hard drives or SATA SSDs.
For power, the board requires both 8-pin EPS connectors for the CPU. A quality 850W power supply is recommended for Ryzen 9-class builds, especially when paired with a high-end GPU. The integrated Wi-Fi 7 module eliminates the need for a separate wireless card, simplifying the build process.

Product Info

The MSI X870E Gaming Plus WiFi was released in 2025 as part of MSI's Gaming Plus lineup. It occupies the mid-to-high tier in the X870E market, offering the full feature set of the flagship chipset without the premium pricing of MSI's MEG series. This positioning makes it a sensible choice for builders who want X870E capabilities without paying for unnecessary extras.
Key specifications include a 14-duet rail 60A SPS VRM, DDR5 support up to 8200+ MT/s (OC), one PCIe 5.0 x16 slot, one M.2 Gen5 x4 slot, and two M.2 Gen4 x4 slots. Networking is handled by Wi-Fi 7, Bluetooth 5.4, and Realtek 5G LAN. The rear panel features a USB4 Type-C port with 40Gbps bandwidth and display output.
Pricing sits around ¥42,000 at major Japanese retailers, which is competitive for an X870E board. MSI's standard warranty period applies, and the board is widely available through official channels and major PC component retailers.

Best Use Cases

For gamers building a high-end Ryzen 9000 system, this motherboard provides the PCIe 5.0 bandwidth needed for the latest GPUs and Gen5 SSDs. The robust VRM design ensures stable performance during extended gaming sessions, even with power-hungry CPUs like the Ryzen 9 series.
Content creators working with video editing or 3D rendering will appreciate the combination of strong CPU power delivery and fast storage options. The USB4 Type-C port enables high-speed transfers to external drives, streamlining workflows involving large media files.
However, budget-conscious builders pairing a Ryzen 5 with a mid-range GPU may find the X870E chipset overkill. In such cases, a B650 or B850 motherboard would offer better value without sacrificing essential features.

Things to Consider

The X870E chipset commands a price premium over B650 and B850 alternatives. If you're building a mid-range system with a Ryzen 5 or Ryzen 7, the extra cost may not translate into tangible benefits. Consider your actual needs before committing to this platform.
M.2 Gen5 SSDs generate significant heat, and while the included EZ M.2 Shield Frozr II helps, adequate case airflow is essential. Ensure your case has good ventilation to prevent thermal throttling on high-performance storage drives.
This board supports DDR5 memory only. If you're upgrading from an older platform with DDR4 modules, you'll need to factor in the cost of new memory. Additionally, while AM5 is expected to support future AMD CPUs, there's no guarantee of long-term compatibility, so plan your upgrade path accordingly.

FAQ

Q: Will this motherboard work with the Ryzen 7 9800X3D?
