AM5 motherboard paired with a Ryzen 7 9800X3D CPU, DDR5 to 8200 MT/s, PCIe 5.0 x16, three M.2 slots, 5G LAN and Wi-Fi 7
CPU +Ryzen 7 9800X3D
This bundle pairs an MSI MAG X870E GAMING PLUS MAX WIFI motherboard with an AMD Ryzen 7 9800X3D processor on the AM5 socket. It targets builders who want a ready-matched CPU and board for gaming or content creation. The combination covers current Ryzen 9000, 8000 and 7000 series compatibility. A 64MB BIOS ROM adds headroom for future microcode updates.
Four DDR5 slots accept up to 256GB in dual-channel mode. JEDEC speeds run at 5600 to 4800 MT/s while overclocked profiles reach 8200+ MT/s with a single-rank DIMM per channel or 6400+ MT/s with dual-rank modules. Three M.2 sockets provide one PCIe 5.0 x4 slot from the CPU and two PCIe 4.0 x4 slots from the chipset, all supporting 2280 and 2260 form factors. Four SATA 6G ports remain for additional drives.
The ATX board delivers a PCIe 5.0 x16 slot for graphics cards when a Ryzen 9000 or 7000 series CPU is installed, dropping to PCIe 4.0 x8 or x4 with Ryzen 8000 series APUs. A second full-length slot and a single x1 slot handle add-in cards. Networking uses Wi-Fi 7 with a 320MHz channel for up to 5.8Gbps throughput and a 5G LAN port. EZ PCIe Release and EZ M.2 Shield Frozr II simplify component swaps. An extended PWM heatsink manages thermals for sustained loads. Realtek ALC897 audio handles onboard sound.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
The combo ships with the CPU already paired to the AM5 socket board, so the processor is supported out of the box.
With Ryzen 9000 series and two single-rank modules the board can reach 8200+ MT/s overclocked; two dual-rank modules top out at 6400+ MT/s.
Yes, the primary x16 slot and the M.2_1 connector both run at PCIe 5.0 speeds directly from the CPU.
