Overview
The ASRock X870 Steel Legend WiFi is a full-size ATX motherboard engineered for AMD Socket AM5 processors, including Ryzen 9000, 8000, and 7000 series CPUs. Finished in a striking white aesthetic, it delivers a compelling blend of next-generation connectivity, robust power delivery, and enthusiast-grade expandability for daily users and performance-focused builders alike. At the heart of its power delivery is a 14+2+1 phase design using 80A Dr.MOS components for VCore and SOC, complemented by enlarged heatsink armor to keep temperatures in check during sustained workloads. Exclusive 20K Black capacitors rated at 1000uF provide higher charge storage, lower power ripple, and more stable output current compared to standard capacitors, contributing to consistent long-term system reliability. Memory support spans four DDR5 DIMM slots with dual-channel operation, accommodating up to 256GB of DDR5 ECC and non-ECC unbuffered memory at speeds up to DDR5-8000+ via overclocking. Both Intel XMP and AMD EXPO memory profiles are supported for straightforward performance tuning. Storage options are extensive: a CPU-direct Blazing M.2 slot (M2_1) delivers PCIe Gen5 x4 bandwidth at up to 128 Gb/s, while two additional Hyper M.2 slots (M2_2, M2_3) offer PCIe Gen4 x4 speeds at up to 64 Gb/s each. Four SATA3 6 Gb/s connectors via ASMedia ASM1061 round out legacy storage needs, and RAID 0, 1, and 10 are supported for NVMe M.2 devices. Connectivity is a standout feature: dual USB4 Type-C rear ports deliver 40 Gb/s throughput and support display output up to 8K 30Hz. A 2.5 Gigabit Ethernet port (Dragon RTL8125BG) handles wired networking, while the integrated 802.11be Wi-Fi 7 module supports 2.4 GHz, 5 GHz, and 6 GHz bands with 160 MHz channel bandwidth, MU-MIMO, and Bluetooth 5.4. Audio is handled by a Realtek ALC4082 codec delivering 7.1-channel HD audio with content protection, individual PCB layers for left/right channel separation, Nahimic Audio software enhancement, and Direct Drive Technology on the front headphone port supporting headsets up to 600 Ohms. The rear I/O panel is fully integrated and includes HDMI 2.1 (4K 120Hz), 2x USB4 Type-C (40 Gb/s), 2x USB 3.2 Gen2 Type-A, 3x USB 3.2 Gen1 Type-A (including Lightning Gaming Ports), 4x USB 2.0, optical S/PDIF out, gold-plated audio jacks, and a BIOS Flashback button for easy BIOS recovery without a CPU or memory installed.
