ASRock X870 Steel Legend WiFi AM5 ATX Motherboard DDR5
The ASRock X870 Steel Legend WiFi is an AMD Socket AM5 ATX motherboard built for users and enthusiasts who demand stable, reliable performance with modern connectivity. It combines an 8-layer PCB, robust power delivery, and WiFi 7 to support the latest Ryzen processors with DDR5 memory overclocking and PCIe 5.0 expansion.
Why this product
14+2+1 power phases for stability
80A Dr.MOS delivers reliable power to the CPU and memory controller, with enlarged heatsink armor to dissipate heat efficiently during overclocking or sustained loads.
WiFi 7 and 2.5G Ethernet
802.11be WiFi 7 and Realtek 2.5G LAN cover both wireless and wired connectivity needs without compromise.
PCIe 5.0 and DDR5 ready
One PCIe 5.0 x16 slot and one blazing M.2 Gen5x4 socket pair with DDR5 support up to 8000+ MHz on overclocked profiles.
8-layer PCB for signal integrity
Stable traces and power distribution reduce noise, lower temperatures and improve energy efficiency for long-term reliability.
USB4 and toolless design
Two rear USB4 ports deliver 40 Gb/s connectivity, and the toolless heatsink speeds installation.

Steel Legend represents the philosophical state of rock-solid durability and irresistible aesthetics. Built around most demanding specs and features, the Steel Legend series aims at daily users and mainstream enthusiasts! Providing a strong array of materials/components to ensure a stable and reliable performance.
The 8 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency, ensures a reliable and long-lasting system while delivering ultimate performance without any compromise.
Derived from the "built for stable and reliable" designing concept, ASRock does not compromise on any details. This motherboard is built with high quality materials, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance by enabling the pre-tested profiles. Make sure the memory modules are Intel® XMP/AMD EXPO™ capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.
SignalRGB unifies your RGB devices, offering seamless customization, game-reactive effects, macro automation, and system monitoring. The official partnership empowers ASRock motherboards with advanced lighting control, enhances compatibility with a diverse range of RGB devices, and provides greater customization flexibility.
The thermistor cable and thermistor header provide an additional source for temperature monitoring, offering customized thermal management solutions.
The reinforced steel slot is capable of supporting PCI Express 5.0 standard.
Unlike most so called pre-mounted I/O shield that is only decorated with fancy color schemes. We reserve more tolerance space and allow IO shield is adjustable when installing, thus fitting chassis perfectly without any mechanical issue.
Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and a power supply. No CPU, RAM or other components are required.
