TUF Gaming B850-PLUS WIFI & Ryzen 7 9700X Combo

This bundle pairs the ASUS TUF GAMING B850-PLUS WIFI motherboard with the AMD Ryzen 7 9700X processor. The board uses the AM5 socket and supports Ryzen 9000, 8000 and 7000 series CPUs. It delivers a 14+2+1 (80A) power stage design on an 8-layer PCB with ProCool connectors for stable current delivery.

DDR5 ATX Platform for High-Performance Builds

The board provides four DDR5 slots with dual-channel architecture and a maximum capacity of 192GB. AEMP technology assists overclocking beyond 8000 MT/s with compatible processors. Connectivity includes Realtek 2.5G wired LAN and Wi-Fi 7 (802.11be) tri-band wireless up to 2.9Gbps. Rear I/O offers ten ports, including USB 20Gbps Type-C and three USB 10Gbps ports, plus a front-panel USB 10Gbps Type-C header.

Dual M.2 PCIe 5.0 Storage Slots

Two M.2 sockets operate at PCIe 5.0 speeds for the fastest available consumer SSDs. Both slots are covered by dedicated heatsinks to maintain performance under sustained workloads. The ATX form factor measures 12.0 x 9.6 inches and requires a chassis with matching mounting points and adequate clearance for the enlarged VRM and PCH heatsinks.

Questions about this item

What DDR5 memory do I need to populate the four slots on this board?

You need DDR5 modules; the board has four slots that run in dual-channel mode and support up to 192 GB total capacity.

Will my existing Realtek 2.5G wired network and Wi-Fi 7 devices work with the onboard networking?

Yes, the motherboard includes a Realtek 2.5G LAN port and 2x2 Wi-Fi 7 (802.11be) across 2.4/5/6 GHz bands, so current 2.5G and Wi-Fi 7 gear will connect directly.

How can I confirm the 14+2+1 80A power delivery is active after assembly?

Enter the BIOS and check the VRM monitoring section; it reports real-time current on each of the 14+2+1 phases so you can verify the 80A stages are operating.
