A Hatsune Miku edition ATX board and 12-core Ryzen 9 9900X with DDR5, PCIe 5.0, dual USB4 and Wi-Fi 7
Model ROG STRIX X870E-H S MIKU
CPU +R9 9900X
This bundle pairs an ASUS ROG STRIX X870E-H S MIKU motherboard with an AMD Ryzen 9 9900X processor. The board uses the AMD X870E chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. It targets builders who want a themed platform with high-end connectivity and AI-ready features. The 12-core, 24-thread CPU reaches a 5.6 GHz max boost clock.
The ATX board requires a compatible chassis, DDR5 memory up to 8000+ MT/s and an ATX power supply with dual ProCool II connectors for the 16+2+1 power stage design. Four M.2 slots (two PCIe 5.0, two PCIe 4.0) and four SATA 6Gb/s ports free up expansion space for storage. Dual USB4 Type-C, USB 20Gbps front-panel, USB 10Gbps rear with PD 3.0 up to 30W, Wi-Fi 7 and Bluetooth 5.4 handle peripherals and networking.
Moving from an older AM5 motherboard adds native PCIe 5.0 graphics and storage support, dual USB4 and the enhanced VRM cooling needed for sustained 12-core loads. The AI Advisor, AI Cache Boost, AI Cooling II and AI Networking II tools simplify tuning. The jump is worth it when building a new AI-focused workstation or high-refresh gaming rig that needs the full X870E feature set.
