ASROCK B550M SE WiFi DDR4 AMD Motherboard

The ASRock B550M SE WiFi is a Micro ATX motherboard measuring 9.6 x 9.6 inches (24.4 x 24.4 cm) built on the AMD B550 chipset and designed for the AM4 socket. It supports AMD Ryzen 3000, 3000 G-Series, 4000 G-Series, 5000, and 5000 G-Series desktop processors, though it is not compatible with the Ryzen 5 3400G or Ryzen 3 3200G. For memory, four DDR4 DIMM slots accommodate up to 128 GB of dual-channel unbuffered memory. Depending on the installed processor, DDR4 speeds can reach up to 4733+ MHz (OC) with Cezanne and Renoir APUs or up to 4533+ MHz (OC) with Vermeer and Matisse CPUs. XMP profiles are also supported. Storage options include four SATA3 6 Gb/s connectors with RAID 0, 1, and 10 support, plus a single Hyper M.2 slot (M2_1, M Key, 2280) capable of PCIe Gen4 x4 (up to 64 Gb/s) when used with Vermeer or Matisse CPUs, or PCIe Gen3 x4 (up to 32 Gb/s) with APU-based processors. Expansion slots consist of two PCIe x16 physical slots — the primary slot operates at Gen4 x16 mode with Vermeer and Matisse CPUs — along with one PCIe 3.0 x1 slot. An Intel 802.11ac dual-band (2.4 GHz / 5 GHz) WiFi module with Bluetooth 4.2 is included and connects via an M.2 Key E socket. Wired networking is handled by a Realtek RTL8111H Gigabit LAN controller supporting Wake- LAN and Energy Efficient Ethernet 802.3az. Audio is provided by a Realtek ALC1220 codec delivering 7.1-channel HD audio with content protection and PCB isolate shielding. The single HDMI port supports HDMI 2.1 output at up to 4K (4096x2160) at 60 Hz with HDR and HDCP 2.3 when using an APU with integrated Radeon Vega graphics. Rear I/O includes four USB 3.2 Gen1 ports (via ASMedia ASM1074 hub), two USB 2.0 ports, one PS/2 port, one RJ-45 LAN port, one HDMI port, audio jacks, and two antenna ports. Internal headers add four more USB 3.2 Gen1 and four USB 2.0 ports. Two RGB LED headers and two addressable RGB LED headers enable Polychrome RGB Sync lighting customization. The board features an 8-phase digital power design with premium 50A power chokes, 2 oz copper inner PCB layers, an XXL aluminum alloy heatsink, high-density glass fabric PCB construction, solid capacitors, and ASRock Full Spike Protection on all USB, audio, and LAN ports. An onboard POST Status Checker (PSC) provides LED indicators for CPU, DRAM, VGA, and BOOT diagnostics.
