Socket AM5 DDR5 platform

The GIGABYTE B850 GAMING X WIFI6E is an ATX motherboard built for AMD Ryzen 7000, 8000 and 9000 series processors. It delivers a 12+2+2 power design and fully covered MOSFET heatsinks for stable operation. Four 288-pin DDR5 slots support up to 256 GB in dual-channel mode.

PCIe 5.0 x16 slot

The primary PCIe 5.0 x16 slot runs at full speed with Ryzen 9000 and 7000 CPUs, while Ryzen 8000 series processors operate at PCIe 4.0 x8 or x4 depending on the specific model. This single slot determines the maximum graphics or NVMe bandwidth available.

Three M.2 slots and EZ-Latch

Three M.2 sockets provide high-speed storage expansion alongside the primary slot. EZ-Latch mechanisms on M.2 and PCIe slots simplify installation without tools. Integrated WIFI6E and 2.5 GbE LAN handle networking, while USB-C adds front-panel connectivity.
