The MSI MPG X870E Carbon WiFi uses the AM5 socket paired with the X870 chipset and follows the standard ATX form factor, measuring 304.8 mm wide by 243.8 mm tall. It accommodates a single CPU and carries no integrated processor or integrated graphics. Wireless connectivity spans Wi-Fi 4 through Wi-Fi 7 (802.11be), and Bluetooth 5.4 is built in, though aptX is not supported. The board includes an HDMI 2.1 output, RGB lighting, and is designed to support overclocking. Reliability features include dual BIOS and a clear CMOS button for straightforward BIOS resets. There is no integrated graphics support, and the board comes with a three-year warranty.
The board supports DDR5 memory across four slots arranged in a dual-channel configuration, with a maximum supported capacity of 256 GB. Standard rated speeds reach up to 5600 MHz, while overclocked profiles can push that figure to 8400 MHz. ECC memory is not supported.
The rear I/O panel offers a broad USB selection, led by two USB 4 40Gbps ports and two Thunderbolt 4 ports, alongside nine USB 3.2 Gen 2 Type-A ports and two USB 3.2 Gen 2 Type-C ports. There are no USB 3.2 Gen 1, USB 2.0, or USB 3.2 Gen 2x2 ports present. Video output is handled by a single HDMI connection, while DisplayPort, DVI, and VGA outputs are absent. Network connectivity is covered by two RJ45 ports, and there are no eSATA or PS/2 ports included.
Internal connectivity includes four M.2 sockets and four SATA 3 connectors for storage, with no SATA 2, U.2, or mSATA options available. For USB expansion via headers, the board provides four USB 3.2 Gen 1 ports, four USB 3.0 ports, one USB 3.2 Gen 2x2 port, and four USB 2.0 ports. Cooling is well catered for with seven fan headers on board. There is no TPM connector present.
The board provides two PCIe 5.0 x16 slots and one PCIe 4.0 x16 slot for expansion cards. Older slot types — including PCIe 3.0 x16, PCIe 2.0 x16, PCIe x8, PCIe x4, PCIe x1, and legacy PCI — are not present, keeping the layout focused entirely on current-generation full-size PCIe interfaces.
The onboard audio subsystem supports 7.1-channel output and delivers a DAC signal-to-noise ratio of 120 dB. Two analog audio connectors are available on the rear panel, and a S/PDIF Out port is included for digital audio passthrough.
The board supports RAID 0, RAID 1, and RAID 10 configurations for storage array setup. RAID 5 and RAID 0+1 are not supported.
