Description
ASRock B860M Steel Legend WiFi arrives as a versatile micro-ATX motherboard built for Intel’s latest LGA 1851 platform and compatible with Intel Core Ultra (Series 2) processors.
This white ASRock B860M Steel Legend WiFi supports DDR5 memory across four DIMM slots in a dual-channel configuration, allowing up to 256 GB of unbuffered, non-ECC RAM and speeds up to 8666 MHz for demanding multitasking and content creation workflows.
Storage options are flexible with one M.2 slot and four SATA III connectors, and the board offers RAID 0/1/5/10 support to combine performance and redundancy according to your needs. The inclusion of SATA cables and an M.2 slot makes fast NVMe and legacy HDD/SSD setups straightforward.
Connectivity is comprehensive: built-in Wi‑Fi 6E (802.11ax) and Bluetooth 5.3 provide modern wireless links while the Dragon RTL8125BG 2.5 Gigabit Ethernet controller delivers high‑speed wired networking. External ports include multiple USB 3.2 Gen 1 and Gen 2 Type‑A ports, USB 2.0, HDMI and DisplayPort 1.4, plus a Thunderbolt port for high-bandwidth peripherals.
Cooling and power delivery are well considered for a micro-ATX board, with two EPS (8‑pin) connectors, a 24‑pin ATX connector, two CPU fan headers, four chassis fan headers, and RGB LED header support for custom builds. A TPM connector adds security options for business or privacy-focused users.
Audio and expansion round out the offering: a Realtek ALC1220 codec supports 7.1 channel audio, and a PCIe x16 Gen5 slot provides a path for high-performance GPUs or add-in cards. The UEFI AMI BIOS (256 Mbit) ensures modern firmware support and Windows 11 x64 compatibility.
Use cases for the ASRock B860M Steel Legend WiFi include compact gaming rigs with high-end connectivity, home content-creation workstations leveraging DDR5 performance, and small form-factor business PCs that require fast wired and wireless networking plus TPM security.
Key selling points: modern LGA 1851 compatibility, DDR5 up to 8666 MHz and 256 GB capacity, Wi‑Fi 6E + 2.5 GbE networking, Gen5 PCIe x16 slot, robust fan and power headers, and white aesthetic for stylish builds.
