MSI MEG X870E Ace Max Wifi7 DDR5 AMD Motherboard

The MSI MEG X870E ACE MAX is a flagship ATX motherboard built on the AMD X870E chipset, designed for AMD Ryzen 9000, 8000, and 7000 series desktop processors in the AM5 socket. It targets enthusiast builders, overclockers, and creative professionals who demand uncompromising connectivity, thermal performance, and stability. At the heart of its power delivery is an 18+2+1 phase Duet Rail Power System using 110A Smart Power Stage MOSFETs and dual 8-pin CPU power connectors, providing the headroom required for sustained high-performance operation with demanding processors. The dedicated OC Engine chip enables independent Base Clock (BCLK) control through asynchronous mode in the BIOS, and MSI states this can boost performance by up to 15% while keeping iGPU, memory, PCIe and NVMe stable during overclocking sessions. Memory support extends to four DDR5 UDIMM slots with a maximum capacity of 256 GB. JEDEC speeds run from 4800 to 5600 MT/s, while overclocked profiles via AMD EXPO reach up to DDR5-9000 MT/s. Ryzen 9000 series users can achieve up to 8400+ MT/s in 1DPC 1R configurations. CUDIMM is supported in Clock Driver bypass mode. Storage is equally generous: five M.2 slots are present, with M.2_1 and M.2_2 connected directly to the CPU and supporting PCIe 5.0 x4 (on Ryzen 9000/7000 series), while M.2_3 through M.2_5 connect via the chipset at PCIe 4.0 x4. Four SATA 6 Gb/s ports supplement NVMe storage. RAID 0, 1, and 10 are supported for SATA devices, and RAID 0, 1, 5, and 10 for NVMe (RAID 5/10 requires Ryzen 9000/7000). Expansion slots include two PCIe x16 mechanical slots and one PCIe x4 slot, all operating at PCIe 5.0 from the CPU (bandwidth varies by processor generation). Networking is handled by a Marvell AQC113CS 10 Gbps LAN controller and a Realtek 8126 5 Gbps LAN controller, complemented by a pre-installed Wi-Fi 7 module supporting 2.4 GHz, 5 GHz, and 6 GHz bands (up to 5.8 Gbps, 320 MHz channels), MU-MIMO, MLO, 4K-QAM, and 802.11be. Bluetooth 5.4 is included. USB connectivity covers every modern standard: two USB 40 Gbps Type-C and two USB 10 Gbps Type-C plus nine USB 10 Gbps Type-A on the rear panel, with front-panel headers for USB 20 Gbps Type-C, four USB 5 Gbps Type-A, and four USB 2.0 ports. Display output via HDMI 2.1 (up to 8K/60 Hz) and USB4 Type-C DisplayPort 1.4 HBR3 (up to 4K/120 Hz) is available on processors with integrated graphics. Audio is powered by the Realtek ALC4082 codec paired with an ESS9219Q combo DAC/HPA, delivering 7.1-channel USB high-performance audio and up to 32-bit/384 kHz playback on the front panel, with optical S/PDIF output also present. Thermal management uses MSI’s Frozr Guard system: wavy fin array heatsinks, direct-touch cross heat-pipe connecting dual MOS heatsinks, a full aluminium IO cover, metal backplate with dedicated thermal pads, double-sided M.2 Shield Frozr for all M.2 slots, and 9 W/mK MOSFET thermal pads. An enlarged passive PCH heatsink replaces a chipset fan to reduce noise and dust. Quality-of-life features include EZ PCIe Release (tool-free GPU removal), EZ Magnetic M.2 Shield Frozr II and EZ M.2 Clip II (screwless SSD installation), Flash BIOS and Clear CMOS rear-panel buttons, a 64 MB BIOS ROM, and TPM 2.0 header. RGB customisation is provided via three ARGB V2 headers and one standard RGB header. The board measures 243.84 mm × 304.8 mm (ATX) and carries a 3-year warranty.
