MSI MEG X670E ACE DDR5 AMD Motherboard

The MSI MEG X670E ACE is a flagship E-ATX motherboard built on the AMD X670E chipset, designed for AMD Ryzen 7000 Series desktop processors using the AM5 socket. It targets enthusiast builders and overclockers who demand headroom for both CPU and memory performance. At the heart of its power delivery sits a 22+2+1 phase design with 90A power stages and dual CPU power connectors, providing the stable, high-current delivery required for demanding workloads and sustained overclocking sessions. The board accommodates up to 128GB of DDR5 memory across four DIMM slots, with support for speeds up to DDR5 6666+ MHz in OC mode via AMD EXPO profiles. JEDEC baseline operation starts at 4800 MHz. Storage flexibility is extensive. Four onboard M.2 slots are provided, with M.2_1 running directly from the CPU at PCIe 5.0 x4 speeds and slots M.2_2 through M.2_4 operating at PCIe 4.0 x4 via the chipset. Six SATA 6G ports round out the storage options, and RAID 0, 1, and 10 configurations are supported for both SATA and NVMe devices. An optional M.2 XPANDER-Z GEN5 DUAL card (sold separately) can expand the total M.2 count to six. Connectivity is a clear strength. The rear panel includes a Marvell AQC113CS-B1-C 10Gbps wired LAN port alongside AMD Wi-Fi 6E with Bluetooth 5.2, supporting 2.4GHz, 5GHz, and 6GHz bands with MU-MIMO TX/RX and 802.11 a/b/g/n/ac/ax standards. The USB complement is equally generous: rear ports include eight USB 3.2 Gen2 Type-A, one USB 3.2 Gen2 Type-C, and two USB 3.2 Gen2x2 Type-C (20Gbps) ports, plus a Type-C DisplayPort output for processors with integrated graphics. Audio is handled by a Realtek ALC4082 codec paired with an ESS ES9280AQ combo DAC/amplifier, delivering 7.1-channel HD audio with S/PDIF output and up to 32-bit/384kHz playback on the front panel. The board ships as a standard E-ATX form factor at 277mm x 304.8mm and carries an 8-layer PCB with 2oz thickened copper layers for long-term signal integrity.
