The MSI PRO X870E-P WIFI ATX motherboard combines a 14+2+1 Duet Rail Power System running 60A Smart Power Stages with the AMD X870E chipset to provide PCIe 5.0 lanes, 40Gbps USB4 connectivity, and Wi-Fi 7 networking for AM5 desktop processors. Built on an 8-layer PCB with 2oz thickened copper within a standard 243.84 mm x 304.8 mm footprint, this board supports AMD Ryzen 9000, 8000, and 7000 series CPUs across Windows 11 64-bit systems.

High-speed 5G LAN, Wi-Fi 7, and 40Gbps USB4 bandwidth

The rear panel delivers network and data interface options designed for fast local transfers and external device connections. A Realtek 8126VB 5G Ethernet controller provides 5 Gbps wired bandwidth for high-speed network access and local NAS workflows. Wireless networking is driven by onboard Wi-Fi 7 (802.11be) alongside Bluetooth 5.4 for peripheral connectivity.

For high-speed external storage, docks, and displays, the rear I/O features a USB4 40Gbps Type-C port that supports DisplayPort 1.4 alt mode. Integrated graphics output is also available via a dedicated HDMI 2.1 port. The rear port selection includes:

• 1x USB4 40Gbps Type-C (supports DisplayPort 1.4)
• 1x USB 20Gbps Type-C
• 2x USB 10Gbps Type-A
• 2x USB 5Gbps Type-A
• 4x USB 2.0 Type-A
• 1x HDMI 2.1 port

14+2+1 power delivery built on an 8-layer copper PCB

To support sustained power requirements under heavy multi-threaded processing loads, the motherboard features a 14+2+1 Duet Rail Power System equipped with 60A Smart Power Stages (SPS). Power and signal routing are integrated into an 8-layer PCB constructed with 2oz thickened copper. This circuit design enhances signal integrity for high-frequency memory and PCI Express buses while aiding passive thermal management across the VRM layout.

PCIe 5.0 expansion and high-speed NVMe M.2 slots

The primary graphics slot uses a PCIe 5.0 x16 interface directly linked to the CPU for maximum bandwidth with current and next-generation graphics cards. Drive options include three onboard M.2 slots and four SATA 6Gb/s ports for multi-drive storage configurations.

• PCIe 5.0 M.2 slot: 1x M.2 slot operating at PCIe 5.0 x4 speeds for Gen5 NVMe solid-state drives.
• PCIe 4.0 M.2 slots: 2x M.2 slots operating at PCIe 4.0 x4 for additional NVMe drives.
• Expansion slots: 1x PCIe 4.0 x16 slot (operating in x4 mode) and 2x PCIe 3.0 x1 slots for expansion cards.
• Storage RAID: Supports RAID 0, 1, and 5 arrays for NVMe drives, plus RAID 0, 1, and 10 for SATA drives.

DDR5 speed support up to 8200+ MT/s with CUDIMM readiness

Four DDR5 DIMM slots accommodate up to 256 GB of dual-channel system memory. The memory trace design supports AMD EXPO memory overclocking profiles, validating speeds up to DDR5 8200+ MT/s (OC). Compatibility with Non-ECC Unbuffered modules extends to CUDIMM (Clock Driver bypass mode), ensuring clean signal transmission at elevated clock frequencies.

Toolless installation features and front panel connectivity

System assembly and hardware maintenance are simplified through onboard EZ design elements. The top PCIe 5.0 M.2 position uses EZ M.2 Shield Frozr II for quick heatsink mounting, while the main PCIe x16 slot incorporates the EZ PCIe Clip II mechanism for quick card removal. Rear-panel Clear CMOS and Flash BIOS buttons allow bios adjustments and firmware updates without opening the system case.
