Combo pairs an AM5 ATX board with a Ryzen 7 9850X3D CPU, offering DDR5 4400 support to 256GB, 16+2+1 80A power stages, dual PCIe 5.0 and dual PCIe 4.0 M.2 slots, WiFi 7, 2.5Gb LAN.
Model TUF GAMING X870-PLUS WIFI
CPU + Ryzen 7 9850X3D
The bundle pairs an ASUS TUF GAMING X870-PLUS WIFI motherboard with an AMD Ryzen 7 9850X3D processor. The board uses the AMD X870 chipset and AM5 socket, supporting Ryzen 9000, 8000 and 7000 series CPUs. Four DDR5 slots accept up to 256 GB of memory at 4400 MT/s with EXPO and AEMP profiles. The 8-core, 16-thread CPU reaches 5.6 GHz and uses second-generation 3D V-Cache for lower latency in games.
ProCool connectors, alloy chokes and durable capacitors deliver stable current to the CPU. Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots all carry large heatsinks. Rear I/O includes dual USB4 40 Gbps Type-C ports, three USB 10 Gbps Type-A ports, four USB 5 Gbps Type-A ports, one USB 2.0 port, HDMI, Realtek 2.5 Gb Ethernet, Wi-Fi 7 and 7.1-channel audio via Realtek ALC1220P. Front-panel headers add a USB 20 Gbps Type-C connector with 30 W power delivery, plus multiple fan and addressable Gen 2 headers.
The jump is worthwhile when you need PCIe 5.0 graphics and storage bandwidth, DDR5 capacity up to 256 GB, and the gaming latency gains of 3D V-Cache on Zen 5. Wi-Fi 7 and dual USB4 40 Gbps ports modernise peripheral and network connectivity. The robust 80 A power design and AI Overclocking, AI Cooling II and PBO Enhancement tools simplify pushing the platform further.

Other versions of this model
The M.2_1 slot runs on PCIe 5.0 x4, so the drive tops out at PCIe 5.0 speeds.
The board includes massive heatsinks on the two PCIe 5.0 M.2 slots and two PCIe 4.0 slots, so allow enough vertical space in the case for those covers.
Drop the Ryzen 7 9850X3D into the AM5 socket, align the triangle markers, lower the retention arm, then apply thermal paste and mount the cooler — forgetting to remove the socket cover is the common slip.
