The ASRock B550 Taichi is an ATX motherboard built on the AMD B550 chipset, providing a stable foundation for AMD Ryzen 3000 series processors. It accommodates up to 128 GB of dual-channel DDR4 memory with supported speeds reaching 4733 MHz for memory-intensive applications. The board leverages the PCIe 4.0 interface across its three primary x16 slots, enabling full bandwidth for current-generation graphics cards and NVMe storage devices. Its power design, supplemented by an 8-pin EPS connector, is engineered to supply consistent voltage to critical components during sustained workloads.
For storage, the motherboard includes two M.2 slots for high-speed drives and eight SATA III ports, with support for RAID 0, 1, and 10 configurations. Connectivity options are comprehensive, featuring a 2.5GbE LAN port for wired networking and integrated Wi-Fi 6 with Bluetooth 5.2 for wireless connections. The rear I/O panel offers a range of USB ports, including Type-A and Type-C connectors operating at USB 3.2 Gen 2 speeds. Onboard audio is handled by the Realtek ALC1220 codec, while video output is provided through both HDMI 2.1 and DisplayPort 1.4 connections.
