Combo Contents

This bundle pairs an MSI X870E GAMING PLUS WIFI motherboard with an AMD Ryzen 9 9900X3D processor. The board uses the AMD X870E chipset and the AM5 socket. The CPU is a 120W Granite Ridge part with 128MB L3 cache and 12MB L2 cache. Integrated AMD Radeon graphics are included on the processor.

Best Fit and Alternatives

Builders who want a ready-to-run AM5 platform with PCIe 5.0 graphics support, triple M.2 slots and Wi-Fi 7 will find this combo convenient. Users needing ECC memory, a smaller form factor or a lower-power CPU should look at other options. The board supports Ryzen 9000, 8000 and 7000 series processors for future upgrades.

Pre-Order Checklist

Verify that your chassis accepts an ATX motherboard and that your power supply can deliver 120W for the CPU plus board and graphics demands. You will need DDR5 UDIMM modules; the board runs up to 256GB across four slots with dual-channel architecture. For M.2 storage, the top slot supports PCIe 5.0 x4 for 2280 or 2260 drives while the other two slots use PCIe 4.0 x4 from the chipset.

Questions about this item

What DDR5 memory speed and capacity do I need already to use the Ryzen 9 9900X3D with this board?

The board accepts four DDR5 UDIMM slots up to 256 GB total, running at 5600–4800 MT/s JEDEC or up to 8200 MT/s when overclocked with Ryzen 9000 series CPUs.

Will my PCIe 4.0 graphics card and PCIe 3.0 add-in cards work in the PCI_E2, PCI_E3 and PCI_E4 slots?

Yes, PCI_E3 runs at PCIe 4.0 x4 from the chipset, while PCI_E2 and PCI_E4 operate at PCIe 3.0 x1, so older cards will function at their native speeds.

How can I confirm the USB 40G port and Wi-Fi 7 are active after building the system?

In Device Manager the USB 40G port appears as a 40 Gbps USB4 controller, and the wireless adapter shows Wi-Fi 7 with a 320 MHz channel capable of 5.8 Gbps link speed.
