The MSI MAG X870E Gaming Plus Max Wi-Fi is built around the AM5 socket and X870 chipset, housed in a standard ATX form factor measuring 304.8 mm × 243.8 mm. It accommodates a single CPU and does not include an integrated processor or integrated graphics. Wi-Fi 7 (802.11be) is supported alongside Wi-Fi 6E, Wi-Fi 6, Wi-Fi 5, and Wi-Fi 4, while Bluetooth 5.4 handles wireless connectivity, though aptX is not supported. Video output is provided through an HDMI 2.1 port. The board includes RGB lighting, dual BIOS, an easy BIOS reset mechanism, and supports overclocking. It does not offer integrated graphics capabilities and carries a three-year warranty.
The board supports DDR5 memory across four slots in a dual-channel configuration, with a maximum capacity of 256 GB. Standard RAM speeds top out at 5600 MHz, while overclocking can push that figure up to 8200 MHz. ECC memory is not supported.
The rear I/O panel offers a broad range of connectivity, including two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2x2 port, and four USB 2.0 ports. On the high-speed side, there is one USB 4 40Gbps port and one Thunderbolt 4 port, both delivered via USB-C; no USB 3.2 Gen 2 or Gen 1 Type-C ports, USB 4 20Gbps, or Thunderbolt 3 ports are present. Video output is limited to a single HDMI port, with no DisplayPort, DVI, or VGA connectors available. Networking is handled by one RJ45 port, and there are no eSATA or PS/2 ports on this board.
For internal expansion, the board provides four USB 3.2 Gen 1 ports and one USB-C 3.2 Gen 2 port through headers, along with six additional USB 2.0 ports via expansion connectors; USB 3.2 Gen 2 and Gen 2x2 expansion headers are not included. Storage connectivity is covered by three M.2 sockets and four SATA 3 connectors, while SATA 2, U.2, and mSATA are absent. Cooling is well catered for with eight fan headers, and the board also features a TPM connector for security module support.
The board's expansion layout is anchored by a single PCIe 5.0 x16 slot for the primary graphics card or other full-bandwidth add-in cards. Beyond that, one PCIe x4 slot and two PCIe x1 slots round out the available expansion options. No PCIe 4.0, 3.0, or 2.0 x16 slots are present, and there are no PCIe x8 slots or legacy PCI slots on this board.
The board supports 7.1-channel audio output, with three analog audio connectors available on the rear I/O. An S/PDIF Out port is not included.
The board supports RAID 0, 1, 5, and 10 configurations, covering a range of performance and redundancy setups. RAID 0+1 is not supported.
