ASUS TUF B850M-PLUS & Ryzen 7 9800X3D Combo
This bundle pairs an AM5 micro-ATX motherboard with an 8-core Ryzen 7 9800X3D processor. The board supplies two DDR5 slots, a PCIe 5.0 x16 SafeSlot, and dual M.2 sockets. It targets gamers and builders who want a compact platform with current-generation connectivity.
Capacity and headroom for gaming and storage
The CPU delivers 16 threads, a 5.2 GHz maximum boost, 96 MB L3 cache and 8 MB L2 cache using second-generation 3D V-Cache technology. Memory scales to 256 GB across two DDR5 DIMMs with AEMP and EXPO profiles. One M.2 slot runs at PCIe 5.0 x4, the second at PCIe 4.0 x4, and AMD RAID 0/1/5/10 is available. Rear I/O includes a USB 3.2 Gen2x2 Type-C port at 20 Gbps, ten total USB ports, Realtek 2.5 Gb LAN and WiFi 6E. The board will saturate with two memory modules, a single graphics card and two M.2 drives.
Upgrade path from AM4 or early AM5 builds
Moving from an AM4 system brings DDR5 bandwidth, PCIe 5.0 graphics and storage lanes, and the 9800X3D’s 3D V-Cache advantage for gaming latency. Builders on first-generation AM5 CPUs gain the Zen 5 architecture, higher boost clocks and the enlarged L3 cache. The jump is worthwhile when the workload benefits from the extra cache and the platform’s newer I/O standards.

Questions about this item
Can I reuse my AM5 DDR5 memory kit with this TUF GAMING B850M-PLUS motherboard?
Yes, the board uses an AM5 socket and has two DDR5 DIMM slots supporting up to 256 GB with AEMP optimization and EXPO profiles, so existing AM5 DDR5 modules will work.
How can I confirm the Ryzen 7 9800X3D is running at its 5.2 GHz max boost after assembly?
Enter the UEFI BIOS or use monitoring software in Windows to verify the CPU hits 5.2 GHz under single-thread load; the unlocked multiplier and 96 MB L3 cache are active by default.
Does the combo include a CPU cooler or do I need to buy one separately?
The bundle supplies the motherboard and the Ryzen 7 9800X3D processor only; a compatible AM5 cooler must be purchased separately.
