Ready for advanced AI PCs

This motherboard and CPU combo targets builders who want a platform prepared for demanding AI workloads. The AMD X870 chipset supports Ryzen 9000, 8000 and 7000 series processors. The included Ryzen 9 9900X3D brings 12 cores built on TSMC 4nm FinFET Granite Ridge Zen 5 architecture with a 120W TDP.

Robust power and connectivity

The board uses a 16+2+1 80A SPS power stage design on an 8-layer PCB with 8+8 pin ProCool connectors. Four M.2 slots accept PCIe 5.0 x4 and PCIe 4.0 x4 drives, while two SATA 6Gb/s ports handle additional storage. Networking includes WIFI7 and 5Gb Ethernet, plus USB4 at 40Gbps and a 20Gbps USB-C port with 30W power delivery.

Practical limits of the AM5 platform

Maximum memory capacity is 256GB across four 288-pin DDR5 slots running dual channel with AMD EXPO, Intel XMP and ASUS AEMP profiles. The CPU provides 128MB L3 cache and 12MB L2 cache alongside integrated AMD Radeon Graphics. A 64MB BIOS chip stores firmware, and the board offers 7.1 channel audio via Realtek ALC1220P.

Questions about this item

Will the 120W Ryzen 9 9900X3D run stably on the 16+2+1 80A power stages?

The 16+2+1 phase design uses 80A SPS power stages on an 8-layer PCB with dual 8-pin ProCool connectors, built to deliver clean current for the 120W Zen 5 CPU under sustained loads.

Can I install four DDR5 modules up to 256GB total and use EXPO or AEMP profiles?

Four 288-pin slots support up to 256GB in dual-channel mode with AMD EXPO, Intel XMP and ASUS AEMP profiles for automatic timing configuration.

How many PCIe 5.0 M.2 drives can I add without sharing bandwidth with the graphics card?

The board provides four M.2 slots; two operate at PCIe 5.0 x4 and two at PCIe 4.0 x4, while the primary GPU slot remains a full PCIe 5.0 x16 link.
