CPU + Ryzen 7 9700X

  • Ready for advanced AI workloads with power and connectivity for demanding applications
  • 16+2+2 power stages rated at 80A each with dual ProCool connectors for multi-core stability
  • Two PCIe 5.0 and two PCIe 4.0 M.2 slots with substantial cooling for fast storage expansion
  • Onboard WiFi 7 and Intel 2.5 Gb Ethernet plus Bluetooth 5.4 for high-performance networking
  • AMD Ryzen 7 9700X with 8 cores and 16 threads on Zen 5 architecture for 100+ FPS gaming

Ready for Advanced AI PC

This combo pairs the ASUS ROG STRIX B850-F GAMING WIFI motherboard with the AMD Ryzen 7 9700X processor. The board uses the AMD B850 chipset on an AM5 socket with a 16+2+2 power solution rated for 80A per stage. It supports DDR5 memory up to 192GB across four 288-pin slots with dual channel architecture. The CPU delivers 8 cores and 16 threads built on the Zen 5 architecture for high frame rates in games.

Suits builders wanting WiFi 7 and PCIe 5.0 storage

The platform includes on-board WiFi 7 (802.11be), Bluetooth 5.4, and Intel 2.5 Gb Ethernet for fast networking. Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots provide substantial high-speed storage capacity with heatsinks. Builders needing 10 SATA ports or legacy memory support should consider a different platform.

Fits an ATX build with dual ProCool power

The motherboard requires an ATX case and dual ProCool power connectors for the robust VRM. Four M.2 slots with cooling free up drive bays, while 19 USB ports including a 20Gbps Type-C front header reduce the need for extra controllers. A PCIe 5.0 x16 SafeSlot with Q-Release Slim secures modern graphics cards. The Realtek ALC4080 codec drives 7.1 surround sound without a separate sound card.

Questions about this item

What DDR5 memory kit do I need to install so the board and the Ryzen 7 9700X will post?

You need unbuffered DDR5 DIMMs in the 288-pin form factor; the board has four slots and supports up to 192 GB total in dual-channel mode with EXPO or AEMP profiles.

Will my existing PCIe 4.0 graphics card and SATA SSDs work at full speed in the PCIe 5.0 x16 slot and the two SATA 6 Gb/s ports?

Yes — the primary x16 slot runs at PCIe 5.0 with Ryzen 9000 and 7000 CPUs, and the two SATA ports deliver 6 Gb/s regardless of which supported processor is installed.

How can I confirm WiFi 7 and Bluetooth 5.4 are active after I finish the build?

In Windows Device Manager the wireless adapter will show as 802.11be and the Bluetooth radio as version 5.4; the Intel 2.5 Gb Ethernet port will also appear as a separate 2.5 Gbps link.
