Extended ATX board for Ryzen 7000, 8000 and 9000 CPUs with DDR5 up to 8200, dual PCIe 5.0 x16, one Gen5 M.2, three Gen4 M.2 and six SATA ports
The X870E Taichi Lite is an extended ATX motherboard built for AMD Ryzen 7000, 8000 and 9000 series processors. It targets builders who need high memory capacity and PCIe 5.0 bandwidth in a single board. Four DDR5 slots accept up to 256 GB of dual-channel memory with EXPO and XMP 3.0 support. The 24+2+1 phase power design delivers 110 A per phase for the VCore and SOC rails.
A Realtek ALC4082 codec pairs with an ESS SABRE9219 DAC and WIMA capacitors to provide 5.1 channel output at 130 dB SNR. Direct-drive technology on the front-panel header drives headsets up to 600 ohms without an external amplifier. Two rear USB4 Type-C ports and one front USB 3.2 Gen2x2 Type-C port supply high-speed peripheral and display connections. Additional USB 3.2 Gen2 and Gen1 ports cover legacy devices.
The CPU provides one M.2 socket running at PCIe 5.0 x4 (128 Gb/s) for a 2280 NVMe drive. The chipset adds three PCIe 4.0 x4 M.2 sockets and six SATA 6 Gb/s ports, all supporting RAID 0, 1 and 10. Two PCIe 5.0 x16 slots operate at x16 or x8/x8 with Ryzen 9000 and 7000 series CPUs, while 8000 series processors reduce the link to x8 or x4. Graphics output is available through two USB4 Type-C ports and one HDMI port.

The 24+2+1 phase design with 110A SPS for VCore and SOC is built for continuous operation and does not require scheduled replacement.
With Ryzen 9000 or 7000 series CPUs the two PCIe 5.0 x16 slots run at full x16 or x8/x8, but with Ryzen 8000 series they drop to Gen4 x8 or x4, so the processor generation is the first bottleneck.
The board uses a 24+2+1 phase 110A SPS VRM with large heatsinks that keep temperatures low under load, and fan headers allow quiet curve tuning for 24/7 operation.
