AMD AM5 Platform Ready

This ATX motherboard uses the AMD X870 chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series processors. It provides four DDR5 slots with a native 4400 speed rating and a maximum capacity of 256 GB. Dual-channel architecture, EXPO and AEMP profiles are available for memory tuning. A 16+2+1 power design with 80 A SPS stages on an 8-layer PCB delivers stable current to the CPU.

Check CPU Generation For Lane Allocation

PCIe 5.0 x16 graphics and two PCIe 5.0 M.2 slots operate at full speed only with Ryzen 9000 or 7000 series CPUs. Ryzen 8000 series processors limit the primary slot to PCIe 4.0 x8 or x4 and the M.2 slots to PCIe 4.0. Verify your processor generation before ordering to match expected bandwidth. Two SATA 6 Gbps ports and two additional PCIe 4.0 M.2 slots remain unaffected by the CPU choice.

Sustained Load Power And Thermal Design

The 80 A SPS power stages, alloy chokes and durable capacitors are built for continuous high-current delivery during long rendering or compute sessions. Massive heatsinks cover the VRM and all four M.2 slots to dissipate heat without relying on extreme airflow. AI Cooling II manages fan curves dynamically to keep temperatures stable over extended workloads rather than short bursts.

Highlights

  • Stable power for heavy workloads with 16+2+1 80A SPS power stages
  • Two PCIe 5.0 M.2 slots plus two PCIe 4.0 slots with large heatsinks
  • Wi-Fi 7 and 2.5Gb Ethernet plus dual USB4 40Gbps Type-C ports
  • AI Overclocking AI Cooling II and AEMP simplify tuning and memory setup
  • Supports Ryzen 9000 8000 7000 series on AM5 socket with DDR5 up to 256GB

Questions about this item

Does the motherboard include all four M.2 heatsinks or must any be bought separately?

The board ships with massive heatsinks covering the two PCIe 5.0 M.2 slots and the two PCIe 4.0 M.2 slots, so no extra heatsinks are required for any of the four M.2_1 through M.2_4 positions.

Should I pick the two PCIe 5.0 M.2 slots or the two PCIe 4.0 M.2 slots for my primary OS drive?

Use either of the two PCIe 5.0 x4 M.2 slots (M.2_1 or M.2_2) for the OS drive to get the highest sequential throughput; the PCIe 4.0 slots remain available for secondary storage.

What does the 80A SPS power-stage rating mean when I install a Ryzen 9000 series CPU?

Each of the 16 main Vcore phases can deliver up to 80 amps, giving the 16+2+1 VRM enough current headroom for high-core-count Ryzen 9000 processors under sustained heavy loads.
