Product information

Description

The ASRock B850 Steel Legend WiFi ATX motherboard supports AMD Socket AM5 processors including Ryzen 7000, 8000 and 9000 series. Built for high-performance desktop systems, it accepts up to 256 GB DDR5 memory, offers multiple high-speed storage options including PCIe 5.0 M.2 and PCIe 4.0 M.2 slots, integrated Wi‑Fi 7 and 2.5 Gb/s LAN, and provides a robust power delivery and cooling design for stable operation under load.

Advantages

This motherboard features an optimized VRM with an exclusive 20K 1000uF capacitor, a 14+2+1 power phase design with integrated Dr.MOS stages and Hi‑Density power connectors, and an 8‑layer PCB to improve stability, thermal performance and energy efficiency. Storage support includes PCIe Gen5 Blazing M.2 and Hyper M.2 Gen4 x4, while connectivity is enhanced by Wi‑Fi 7, a front-panel USB 3.2 Gen2x2 Type‑C header and Dragon 2.5 Gb/s LAN. Additional usability is provided by enlarged M.2 heatsinks with anti-drop screws, toolless M.2 installation, PWM/DC fan detection, thermistor headers and ASRock Fan‑Tastic tuning.

Suitable for

  • High-performance gaming desktops with AMD Ryzen AM5 processors
  • Content creators and workstation users requiring fast storage and networking
  • Enthusiasts who overclock DDR5 memory and CPUs
  • Custom PC builders seeking a feature-rich ATX motherboard with modern I/O

Key specifications

  • Chipset: AMD B850
  • Form factor: ATX
  • CPU socket: Socket AM5 (supports Ryzen 7000/8000/9000 series)
  • Memory: 4 × DDR5 slots, up to 256 GB, XMP/EXPO support
  • Power design: 14+2+1 phases, Dr.MOS, Hi‑Density power connector, exclusive 20K 1000uF capacitor
  • PCB: 8‑layer PCB
  • Storage: PCIe Gen5 M.2 (Blazing M.2), PCIe Gen4 M.2 (Hyper M.2 Gen4 x4), SATA III
  • Networking: Wi‑Fi 7, Dragon 2.5 Gb/s LAN
  • USB: Front-panel USB 3.2 Gen2x2 Type‑C header (20 Gbps), multiple rear USB ports
  • Audio: Nahimic audio features (noise suppression, echo cancellation, voice stabilizer, sound tracker)

How to use

Install the ASRock B850 Steel Legend WiFi into a compatible ATX chassis, mount an AM5 CPU and DDR5 memory modules into the provided sockets, then connect power using the Hi‑Density CPU and ATX power connectors. For high‑speed storage, install M.2 SSDs into the designated M.2 slots and secure them using the enlarged M.2 heatsink with anti‑drop screw or the toolless quick‑release mechanism. Configure fan control, thermistor inputs and fan curves via the UEFI or ASRock Fan‑Tastic Tuning utility. Enable Intel XMP or AMD EXPO profiles in BIOS to apply pretested DDR5 overclocking settings if memory modules support them.

Usage recommendations

For reliable overclocking and sustained performance, use high‑quality power supplies rated to handle increased CPU and memory currents, keep M.2 SSDs cooled with the provided heatsinks, and update the motherboard BIOS to the latest version before applying aggressive memory or CPU overclocks. Monitor temperatures via thermistor headers and adjust fan curves to maintain system stability.
