Ready for AM5 Builds

This bundle pairs an ASUS PRIME B850M-A micro-ATX motherboard with an AMD Ryzen 9 9950X3D processor. The combination targets enthusiasts who want a single validated kit for a new AM5 platform build. It includes the CPU and board together so compatibility is assured out of the box.

16-Core Zen 5 Processor

The Ryzen 9 9950X3D delivers 16 cores built on TSMC 4nm FinFET Granite Ridge architecture. It provides 128 MB of L3 cache and 16 MB of L2 cache for high-throughput workloads. Integrated AMD Radeon graphics supply a display output without a discrete card.

VRM Heatsinks and M.2 Cooling

The board uses an 8+2+1 power module layout on a 6-layer PCB with Digi+ VRM digital control. VRM heatsinks, thermal pads and dedicated M.2 heatsinks manage heat from the 170 W CPU and fast storage. A water-pump header and 4-pin PWM/DC fan connectors allow flexible cooling configurations.

商品問答

What does the DDR5 8000 MT/s overclock rating mean for my memory choice?

The motherboard can run DDR5 memory at speeds up to 8000 MT/s when overclocked, so you can install high-frequency DDR5 kits and enable the XMP or EXPO profile in the UEFI BIOS to reach that rate.

What does the PCIe 5.0 slot support in practice?

The primary expansion slot is wired for PCIe 5.0, letting a compatible graphics card or add-in card use the full 5.0 bandwidth that the Ryzen 9 9950X3D provides.

What mounting pattern and form factor does the PRIME B850M-A use?

The board follows the micro-ATX form factor and uses the standard four-hole micro-ATX mounting pattern, so it fits any chassis designed for micro-ATX or larger motherboards.
