CPU + Ryzen 7 9800X3D

  • Stable power for demanding workloads with 16+2+1 80A SPS power stages
  • Faster gaming response via Ryzen 7 9800X3D 2nd-gen 3D V-Cache technology
  • Four M.2 slots including two PCIe 5.0 x4 for high-speed storage expansion
  • WiFi 7 and 2.5Gb LAN plus dual USB4 40Gbps for ultrafast connectivity
  • AI overclocking and cooling simplify tuning while boosting performance automatically

Combo purpose

The ASUS TUF GAMING X870-PLUS WIFI motherboard paired with the Ryzen 7 9800X3D CPU targets enthusiasts building an advanced AI PC or high-performance gaming rig. The AM5 socket supports Ryzen 9000, 8000 and 7000 series processors. The bundle delivers a 16+2+1, 80A SPS power design on an 8-layer PCB with ProCool connectors, alloy chokes and durable capacitors for stable delivery. ASUS AI Overclocking, AI Cooling II and AEMP simplify setup.

Memory and storage headroom

Four DDR5 slots accept up to 256GB of un-buffered memory at 4400 standard with EXPO and AEMP support; non-ECC modules gain on-die ECC. Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots (all 2280) provide fast primary storage, while SATA 6 Gbps with RAID 0/1/5/10 adds capacity. RAID 5 requires a Ryzen 9000 CPU. The board runs out of M.2 lanes beyond the four onboard slots.

Connectivity and mounting reality

Rear I/O supplies dual USB4 40Gbps Type-C, three USB 10Gbps Type-A, four USB 5Gbps Type-A, one USB 2.0 Type-A, HDMI, Realtek 2.5Gb Ethernet, WiFi 7 and 7.1 audio via Realtek ALC1220P. Front-panel adds a USB 20Gbps Type-C header with 30W PD fast-charge, a USB 5Gbps header and two USB 2.0 headers. Fan control uses one CPU, one CPU OPT, one AIO pump, four chassis and one W_PUMP+ header, plus three addressable Gen 2 headers for lighting. ATX form factor fits standard cases.

Questions about this item

Will the Ryzen 7 9800X3D run in my existing AM5 cooler and DDR5 memory?

The CPU fits the AM5 socket used by Ryzen 7000, 8000 and 9000 series processors, so any AM5-compatible cooler mounts without change. The board has four DDR5 slots supporting up to 256 GB in dual-channel mode, so your current DDR5 modules install directly.

How do I confirm the two PCIe 5.0 M.2 slots and USB4 ports are active after building?

Enter the UEFI and verify M.2_1 and M.2_2 show PCIe 5.0 x4 link speed, then check that both rear USB4 Type-C ports enumerate at 40 Gbps in the USB controller view. Windows Device Manager should list the Realtek 2.5Gb Ethernet and Wi-Fi 7 adapters without errors.

What ships in the combo box and what must I supply myself?

The package contains the TUF GAMING X870-PLUS WIFI motherboard and the Ryzen 7 9800X3D processor. You must provide DDR5 memory, an AM5 CPU cooler, a graphics card for the PCIe 5.0 x16 slot, storage for the four M.2 slots and six SATA ports, and an ATX power supply for the 16+2+1 80A power stage design.
