Combo Core

This bundle pairs a Sapphire NITRO+ B850M WIFI motherboard with an AMD Ryzen 7 9700X 8-core 16-thread Zen5 processor. The board uses the AM5 socket and B850 chipset to support Ryzen 7000, 8000 and 9000 series CPUs. It targets gamers and creators who want a ready-to-run platform for 2K or 4K workloads.

Power Phase Cooling

A 12+2+1 phase power design feeds the 9700X up to its 5.5 GHz maximum boost while the enhanced thermal solution keeps voltages stable during long sessions. Rear I/O includes HDMI, DisplayPort, 2.5G LAN, WiFi 6E with Bluetooth 5.3, four USB 2.0, three USB 3.2 Gen2 Type-A and one USB 3.2 Gen2 Type-C. Front-panel headers provide one USB 2.0 pin connector.

PCIe 5.0 Limits

The single PCIe 5.0 x16 slot and PCIe 5.0 M.2 connector deliver the highest storage and graphics bandwidth the B850 chipset allows, but only one device can use the 5.0 link at a time. DDR5 memory tops out at 8000 MT/s overclocked across four slots for a 192 GB maximum. Realtek ALC897 audio is limited to 5.1 channels and the second x4 slot runs at PCIe 4.0 speeds.
