Motherboard and CPU combo for AM5 builds

This bundle pairs the ASUS TUF GAMING X870-PLUS WIFI motherboard with the AMD Ryzen 9 9900X processor. The board uses the AMD X870 chipset and AM5 socket, supporting Ryzen 9000, 8000 and 7000 series CPUs. It targets enthusiasts who want a single validated package for high-end desktop systems.

Sustained load handling with 80A power stages

The 16+2+1 phase design uses 80A SPS power stages on an 8-layer PCB with ProCool connectors, alloy chokes and durable capacitors. AI Overclocking, AI Cooling II, Dynamic OC Switcher, Core Flex and PBO Enhancement manage thermals and voltage during extended workloads. Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots include large heatsinks to maintain throughput under continuous I/O.

ATX layout with WiFi 7 and dual USB4 40Gbps

The ATX form factor provides four DDR5 slots up to 256GB, a PCIe 5.0 x16 slot, four M.2 sockets and extensive rear I/O. Back panel includes WiFi 7, 2.5Gb Ethernet, two USB4 40Gbps Type-C ports, three USB 10Gbps Type-A, four USB 5Gbps Type-A, one USB 2.0, HDMI and 7.1 audio jacks. Internal headers add a USB 20Gbps Type-C with 30W PD, multiple fan and pump headers, and addressable Gen 2 RGB connectors.

Questions about this item

How loud and hot does the 16+2+1 80A SPS power delivery get when the Ryzen 9 9900X runs all day?

The 16+2+1 80A SPS power stages with alloy chokes and 8-layer PCB are built for stable delivery under sustained loads, while AI Cooling II manages fan curves to balance thermals and acoustics during long sessions.

What cooler and memory must I already own to use this AM5 combo?

You need an AM5-compatible CPU cooler and DDR5 modules; the board supports up to 256 GB across four slots with EXPO and AEMP profiles for automatic tuning.

Will my PCIe 4.0 graphics card and SATA drives work alongside the new PCIe 5.0 M.2 slots?

Yes — the PCIe 5.0 x16 slot runs PCIe 4.0 cards at full speed, four SATA 6 Gbps ports remain active, and the two PCIe 4.0 M.2 slots add fast storage without disabling older interfaces.
