The ASRock B850 Steel Legend WiFi is an ATX motherboard built on the AMD B850 chipset for the AM5 socket. It provides native support for AMD Ryzen 7000, 8000, and 9000 series processors, establishing a foundation for a high-performance computing system. The board incorporates four DDR5 DIMM slots in a dual-channel configuration, accommodating a maximum of 256 GB of system memory. These slots are optimized for memory clock speeds reaching up to 8000 MHz, which facilitates substantial bandwidth for demanding applications and multitasking workloads.
This motherboard offers extensive connectivity and storage options. It is equipped with a primary PCIe 5.0 x16 slot for modern graphics cards and an additional PCIe 4.0 x16 slot for other expansion cards. For storage, the board includes four M.2 slots, one of which operates at PCIe 5.0 speeds for high-performance NVMe SSDs, complemented by four SATA III ports. Networking is handled by an integrated 2.5 GbE LAN port, and a Wi-Fi 7 module with Bluetooth 5.4 provides advanced wireless connectivity. The rear I/O panel features a comprehensive selection of USB ports, an HDMI 2.1 output, and audio jacks driven by the Realtek ALC4082 codec.
