MSI's newest high‑end board, the MEG X870E Ace Max, drops the EATX silos for a more common ATX layout while keeping flagship power delivery. It ships with an 18‑phase VRM, a 512 Mb BIOS, and a rear M.2 slot that supports PCIe 5 x4, putting it at the top of the AM5 tier for gaming enthusiasts and players.

With ten PCIe 5 x16 slots in various lane configurations, the board offers unmatched expandability, including a single PCIe 5 x4 slot and dual USB4 40 Gbps Type‑C ports. Networking stacks a 10 Gbps Marvell AQC113CS and a 5 Gbps Realtek chip, while Wi‑Fi 7 arrives via dual antenna connectors, catering to the most demanding workloads.

Memory support reaches 256 GB across four DDR5 DIMM slots, with a single‑rank 9 kHz DDR5‑9000 OC possibility. Storage options grow to four SATA 6 Gb/s drives plus six M.2 slots, split between PCIe 5 x4 and PCIe 4 x4 lanes, giving users ample room for high‑speed SSDs and RAID arrays in modern builds.

MSI’s Ace Max targets enthusiasts who need enterprise‑grade features without the X870E’s size. The 18‑phase cooling solution and dual Wi‑Fi 7 ports make it a solid choice for overclockers and content creators alike. At a price that matches its premium build, it stays a top pick for anyone serious about AM5 performance.
