AM5 Combo for Gaming Builds

The bundle pairs an MSI MAG X870E TOMAHAWK MAX WIFI PZ motherboard with an AMD Ryzen 7 9800X3D processor on the AM5 platform. It targets enthusiasts who want a high-performance foundation for gaming and productivity without selecting parts separately. The X870E chipset unlocks the full feature set of the Ryzen 9000 series CPU.

Back-Connect Layout and VRM Cooling

A back-connect design moves primary connectors to the rear for a cleaner front view and easier cable routing. The board includes a 64MB BIOS ROM for broader CPU compatibility and an OC Engine clock generator to support sustained processor boost behaviour. VRM and M.2 heatsinks manage thermal load during extended workloads.

Quad M.2 and USB 40G Ready

Four M.2 slots are provided: two from the CPU supporting PCIe 5.0 x4 for 22110 and 2280 drives, plus two from the chipset. A front-panel USB 4 port delivers 40Gbps bandwidth. Connectivity includes 5G LAN and Wi-Fi 7 with a 320MHz channel, while 7.1-channel audio uses the Realtek ALC4080 codec.

Questions about this item

Will this board fit a standard ATX case and does the back-connect layout change front-panel wiring?

The board uses the ATX form factor so it mounts in any standard ATX case. The back-connect design moves motherboard headers to the rear edge, leaving the front panel free of cables and making front-panel wiring simpler.

Which DDR5 speeds and capacities are officially supported with the Ryzen 7 9800X3D?

Four 288-pin slots accept up to 256 GB of DDR5 in dual-channel mode. CUDIMM modules are supported in clock-driver bypass mode only; non-ECC unbuffered DIMMs are required.

Can I run two graphics cards or add multiple M.2 drives without sharing bandwidth?

The CPU provides one PCIe 5.0 x16 slot and two PCIe 5.0 x4 M.2 sockets. The chipset adds one PCIe 4.0 x4 M.2 socket, one PCIe 4.0 x4 slot and one PCIe 3.0 x1 slot, so a second GPU would run at x4 from the chipset.
