The MSI MEG X870E Ace Max uses the AM5 socket with the X870 chipset and comes in the standard ATX form factor, measuring 304.8 mm wide and 243.8 mm tall. It accommodates a single CPU and has no integrated processor or integrated graphics. Wireless connectivity is handled by a built-in module supporting Wi-Fi 4 through Wi-Fi 7 (802.11be), paired with Bluetooth 5.4, though aptX is not supported. The board outputs video via HDMI 2.1, includes RGB lighting, and is designed with overclocking in mind. Reliability features include a dual BIOS setup and a straightforward BIOS reset mechanism, and the board carries a three-year warranty.
The board features four DDR5 memory slots arranged in a dual-channel configuration, supporting a maximum capacity of 256 GB. Standard operation runs at up to 5600 MHz, while overclocking can push speeds as high as 9000 MHz. ECC memory is not supported.
The rear I/O panel offers a substantial USB lineup, including nine USB 3.2 Gen 2 Type-A ports and two USB 3.2 Gen 2 Type-C ports, with no USB 2.0 or Gen 1 ports present. High-bandwidth connectivity is further covered by two USB 4 40Gbps ports and two Thunderbolt 4 ports, while USB 4 20Gbps and USB 3.2 Gen 2x2 are absent. For networking, two RJ45 ports are available. Video output is limited to a single HDMI connection, with no DisplayPort, DVI, or VGA outputs on offer. There are no eSATA or PS/2 ports.
For internal expansion, the board provides four USB 3.2 Gen 1 headers and four USB 2.0 headers, along with one USB 3.2 Gen 2x2 header; Gen 2 and USB-C Gen 2 expansion headers are not included. Storage is well served by five M.2 sockets and four SATA 3 connectors, while SATA 2, U.2, and mSATA are absent. Cooling is managed through eight fan headers, and a TPM connector is present for security module installation.
The board offers three expansion slots in total: one PCIe 5.0 x16 slot for the primary graphics card or other full-bandwidth add-in cards, alongside one PCIe x8 slot and one PCIe x4 slot. There are no PCIe 4.0, 3.0, or 2.0 x16 slots, and no PCIe x1 or legacy PCI slots are present.
The onboard audio supports 7.1-channel output and delivers a DAC signal-to-noise ratio of 130 dB, indicating a clean audio signal. Two analog audio connectors are available on the rear panel, and a S/PDIF output port is included for digital audio passthrough to compatible external devices.
The board supports RAID 0, 1, 5, and 10 (1+0), covering the most common configurations for both performance-oriented and redundancy-focused storage setups. RAID 0+1 is not supported.
