Asrock B850 Steel Legend WiFi ATX Motherboard | AM5 | 4x DDR5 Slots | Wi-Fi 7
Description
The Asrock B850 Steel Legend WiFi brings AMD's latest B850 chipset to an ATX platform with a distinctive white aesthetic that suits modern builds. This mainstream board supports AMD's current Ryzen 7000, 8000, and 9000 series processors through the AM5 socket, making it a solid choice for anyone building a contemporary AMD system. The Steel Legend series targets builders who want reliable performance without paying enthusiast-level prices, and this B850 model delivers exactly that with comprehensive connectivity and future-ready features.
Memory support extends to 256GB of DDR5 across four DIMM slots, with both ECC and non-ECC compatibility for flexibility. Storage connectivity is generous with four M.2 slots - one PCIe 5.0 slot for the fastest NVMe drives and three PCIe 4.0 slots for additional storage. For graphics, you get one PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot, covering single-card setups and providing an upgrade path. Modern connectivity includes Wi-Fi 7, Bluetooth 5.4, 2.5 Gigabit Ethernet, and USB 3.2 Gen 2x2 for high-speed peripherals.
The board includes practical extras like dual 8-pin EPS power connectors for stable CPU power delivery, two CPU fan headers for cooling flexibility, and RGB LED pin headers for custom lighting setups. An antenna comes in the box for the wireless functionality, and the white Steel Legend styling adds visual appeal to windowed cases. The AMI UEFI BIOS provides straightforward system configuration, while 7.1-channel audio handles sound without requiring a separate sound card.
