Overview

The ASRock B650 Steel Legend WiFi is an ATX motherboard built around AMD's B650 chipset and AM5 socket, supporting Ryzen 7000, 8000, and 9000 Series processors. Its 14+2+1 power phase design with 80A Dr.MOS power stages delivers clean, stable power to the CPU, making it well suited for overclocking and sustained workloads. Four DDR5 DIMM slots support dual-channel memory up to 256GB with overclocked speeds of 7200 MHz and beyond, giving builders plenty of headroom for memory-intensive tasks like video editing, 3D rendering, and large dataset processing.

Expansion and storage options are equally strong. A PCIe 5.0 x16 slot is ready for next-generation graphics cards, while the Blazing M.2 slot runs at PCIe Gen 5 x4 for the fastest NVMe SSDs currently available. Two additional Hyper M.2 slots at PCIe Gen 4 x4 and four SATA III ports round out the storage connectivity. Networking is covered by onboard WiFi 6E (802.11axe) with Bluetooth and a Dragon 2.5 Gigabit LAN port. The rear I/O panel features USB 3.2 Gen2x2 Type-C, USB 3.2 Gen2 Type-A, and multiple USB 3.2 Gen1 ports, along with HDMI and DisplayPort outputs for integrated graphics use. BIOS Flashback and ASRock's Auto Driver Installer simplify initial setup, and Nahimic Audio processing enhances the Realtek ALC4082 7.1-channel codec for immersive sound.

Pros & Cons

👍 Pros

  • PCIe 5.0 x16 slot and a Gen 5 M.2 slot provide future-proof bandwidth for next-gen GPUs and SSDs.
  • Robust 14+2+1 power phase design with 80A Dr.MOS VRMs supports stable overclocking on high-core-count Ryzen CPUs.
  • Extensive USB connectivity including USB 3.2 Gen2x2 Type-C, totaling 18 USB ports across front and rear.
  • Onboard WiFi 6E and 2.5G LAN eliminate the need for add-in networking cards.
  • BIOS Flashback enables CPU-less BIOS updates for hassle-free new processor support.

👎 Cons

  • B650 chipset lacks the additional PCIe 5.0 lanes found on the higher-end X670E for users wanting Gen 5 on multiple slots simultaneously.
  • No integrated 10 Gigabit Ethernet, which may matter for high-throughput workstation or NAS use cases.
  • ATX form factor will not fit in compact Mini-ITX or Micro-ATX cases.
  • Realtek ALC4082 audio codec, while capable, does not match the quality of dedicated sound cards for audiophile use.
