Overview
The ASRock Z490 Taichi WiFi is a full-size ATX motherboard (12.0 in x 9.6 in / 30.5 cm x 24.4 cm) built on the Intel Z490 chipset and designed for 10th Generation Intel Core processors using the LGA 1200 socket. Its 15-phase Dr.MOS power delivery, paired with a 50A integrated power stage and premium 60A power chokes, is engineered to sustain stable voltage to the processor during extended workloads and overclocking sessions. Memory support spans four DDR4 DIMM slots capable of holding up to 128 GB total, with native speeds up to DDR4 2933 and overclocked profiles reaching DDR4 4666+ (OC) via Intel XMP 2.0. Three Ultra M.2 slots (all PCIe Gen3 x4, two also SATA3-capable) sit beneath a full-coverage aluminium heatsink, complemented by eight SATA3 ports for conventional drives. Connectivity is a standout. Wireless is handled by an Intel Wi-Fi 6 (802.11ax) module supporting dual-band 2.4/5 GHz operation, MU-MIMO, and Bluetooth 5.1. Wired networking combines a Dragon 2.5 Gb/s port (Realtek RTL8125BG) with an Intel I219V Gigabit port. USB ports on the rear include one USB 3.2 Gen2x2 Type-C (20 Gb/s), two USB 3.2 Gen2 Type-A (10 Gb/s), and five USB 3.2 Gen1 ports. Display output relies on HDMI 1.4 (4K @ 30 Hz) and DisplayPort 1.4 (4K @ 60 Hz), available only when using a processor with integrated graphics. Audio is handled by a Realtek ALC1220 codec paired with an ESS SABRE9218 DAC for the front-panel header (rated at 130 dB SNR), WIMA audio capacitors on front outputs, and Nahimic Audio software. Expansion consists of three PCIe 3.0 x16 slots (supporting NVIDIA SLI and AMD 3-Way CrossFireX) and two PCIe 3.0 x1 slots. The board ships with two RGB LED headers, two addressable LED headers, and ASRock Polychrome SYNC for lighting control. Additional highlights include a BIOS Flashback button, onboard Dr. Debug LED indicator, Clear CMOS button, and a 2 oz copper PCB for improved thermal management.
