Model X870 PRO RS

Style White

  • Supports Ryzen 7000, 8000 and 9000 series CPUs
  • 14+2+1 power phases with 80A Dr.MOS for stable delivery
  • Four DDR5 slots up to 8000+ OC, 256GB max capacity
  • PCIe 5.0 x16 and Blazing M.2 Gen5x4 128 Gb/s speed
  • Dual USB4 Type-C, 7.1 audio with Realtek ALC1220

Socket and processor support

The board uses the AM5 socket and accepts Ryzen 7000, 8000 and 9000 series processors. It is built around the AMD X870 chipset and targets builders who want a full-size ATX platform for current and upcoming CPUs.

Primary expansion slot

One PCIe 5.0 x16 slot runs at Gen5 x16 with 9000 and 7000 series chips, but drops to Gen4 x8 or x4 with 8000 series parts. A second PCIe 4.0 x16 slot operates at x4 and is disabled when the M2_2 drive is populated.

Installation notes

Standard ATX mounting applies with four DDR5 DIMM slots supporting up to 256 GB. The 14+2+1 phase VRM uses 80 A Dr.MOS and 1000 uF capacitors. Builders should check CPU cooler clearance near the power heatsinks and verify M.2 slot selection to keep the second PCIe slot active.

Questions about this item

What does the 14+2+1 phase power design with 80A Dr.MOS mean for a Ryzen 9000 series CPU in daily use?

The 14+2+1 phase layout with 80A Dr.MOS delivers stable current to the CPU VCore and SOC rails, reducing voltage ripple and keeping temperatures lower during heavy workloads or overclocking.

How does the PCIe 5.0 x16 slot behave when a Ryzen 8000 series processor is installed?

With Ryzen 8000 series CPUs the primary PCIe 5.0 x16 slot runs at Gen4x8 or Gen4x4 depending on the specific processor variant, not at the full Gen5x16 speed.

What clearance and mounting points does the ATX board need inside a case?

The board follows the standard ATX form factor with 288-pin DDR5 slots, four SATA 6Gb/s ports, three M.2 sockets (2230, 2242, 2260, 2280) and rear I/O including two USB4 Type-C, one HDMI and 7.1 channel audio jacks.
