ASRock B850 Steel Legend WiFi AM5 Motherboard

The ASRock B850 Steel Legend WiFi delivers robust performance for AMD Ryzen 9000, 8000, and 7000 series processors. This ATX motherboard features a 14+2+1 phase power design with 80A Dr.MOS for VCore and SOC, ensuring stable power delivery for demanding workloads and overclocking.

Memory and Storage Capabilities

Equipped with four DDR5 DIMM slots supporting dual-channel memory up to 8000+ MHz (OC) with a maximum capacity of 256GB. The motherboard includes one PCIe Gen5 x4 M.2 socket (Blazing M.2) and three PCIe Gen4 x4 M.2 sockets (Hyper M.2), providing extensive high-speed storage options. Four SATA3 ports offer additional connectivity for legacy drives. The toolless multi-layer M.2 heatsink design simplifies installation while maintaining optimal thermal performance.

Expansion and Graphics

The primary PCIe 5.0 x16 slot features 15µ gold contacts for enhanced conductivity and supports x16 mode with Ryzen 9000 and 7000 series processors. A secondary PCIe 4.0 x16 slot (x4 mode) provides additional expansion capability. Integrated AMD RDNA graphics output through HDMI 2.1 TMDS/FRL 8G supports HDR, HDCP 2.3, and 4K resolution at 120Hz. The Lite Release Design includes an enlarged latch for simplified graphics card installation and removal.

Connectivity Features

Realtek 2.5 Gigabit LAN delivers high-speed wired networking with Dragon software for bandwidth optimization. The 802.11be WiFi 7 module supports 2.4GHz/5GHz/6GHz frequency bands with 160MHz channel bandwidth and Bluetooth 5.4. USB connectivity includes two USB 3.2 Gen2 Type-C ports (10 Gb/s) on the rear panel, one USB 3.2 Gen2x2 Type-C header for front panel connection, seven USB 3.2 Gen1 ports, and eight USB 2.0 ports. Lightning Gaming Ports provide optimized performance for peripherals.

Audio and Power Design

The Realtek ALC4082 7.1 CH HD audio codec with Nahimic Audio features individual PCB layers for left and right audio channels. Direct Drive Technology on the front headphone port supports impedance up to 600 Ohms. ASRock's exclusive 20K capacitors with 1000µF capacitance and 20,000-hour lifespan ensure long-term stability. M.2 bottom heatsinks dissipate heat through the PCB for sustained performance.

BIOS and Software

The 256Mb AMI UEFI BIOS includes ASRock Full HD GUI, EZ Mode for simplified configuration, and Instant Flash for easy updates. BIOS Flashback button enables firmware updates without CPU installation. ASRock Polychrome SYNC controls RGB LED headers and addressable LED headers. Smart fan control manages six fan connectors (CPU_FAN1/2, CHA_FAN1-3, AIO_PUMP) with automatic 3-pin or 4-pin detection.
