Motherboard and CPU Combo

This package pairs the ASUS TUF GAMING X870-PLUS WIFI motherboard with the AMD Ryzen 9 9950X3D processor. The board uses the AMD X870 chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. It targets builders who want a single validated platform for gaming and heavy workloads. The CPU delivers 16 cores with 128MB L3 cache and integrated Radeon graphics.

Power Stages and AI Controls

The 16+2+1 80A SPS power stages, 8-layer PCB and ProCool connectors deliver stable current to the 170W processor. ASUS AI Overclocking, AI Cooling II and AEMP automate frequency, fan curves and memory tuning. Dynamic OC Switcher, Core Flex and PBO Enhancement give manual headroom for advanced users. Massive heatsinks cover the two PCIe 5.0 and two PCIe 4.0 M.2 slots.

Connectivity Limits

Dual USB4 40Gbps Type-C ports and a front USB 20Gbps header with 30W power delivery share total bandwidth across attached devices. Wi-Fi 7 and Realtek 2.5Gb Ethernet provide wireless and wired network options. Four DDR5 slots accept up to 256GB at 4400 MT/s in dual-channel mode with ECC support. The PCIe 5.0 x16 slot runs at x16 with Ryzen 9000 and 7000 CPUs, but drops to x8 or x4 with Ryzen 8000 series.
