CPU + Ryzen 9 9950X

  • Ready for AMD Ryzen 9000, 8000 and 7000 series processors with AM5 socket
  • 16 cores and 32 threads on Zen 5 architecture boost up to 5.7 GHz
  • 16+2+1 power stages rated 80A with dual ProCool II connectors for multi-core stability
  • Two PCIe 5.0 and two PCIe 4.0 M.2 slots with substantial cooling solutions
  • Dual USB4 Type-C ports plus USB 20Gbps front-panel and USB 10Gbps rear with PD 3.0 30W

Hatsune Miku Edition Combo

This bundle pairs the ROG STRIX X870E-H S MIKU motherboard with a Ryzen 9 9950X processor. The AM5 socket supports Ryzen 9000, 8000 and 7000 series CPUs. The 16-core, 32-thread chip reaches a 5.7 GHz max boost and includes 64 MB L3 cache. It targets builders who want a themed platform for gaming and heavy workloads.

Installation Notes

The ATX board fits standard chassis and uses dual ProCool II power connectors for the 16+2+1 phase VRM rated at 80 A per stage. Mount the CPU, attach the cooler, then populate up to four DDR5 slots for a 256 GB dual-channel limit. The I/O shield is integrated, and M.2 heatsinks are pre-fitted. Common issues include forgetting the second 8-pin EPS cable or seating DDR5 modules unevenly.

Interface Limits

The primary PCIe 5.0 x16 slot runs at x16 with Ryzen 9000 and 7000 series but drops to x8 or x4 with 8000 series chips. Two M.2 slots operate at PCIe 5.0 x4 and two at PCIe 4.0 x4; all share CPU lanes. Dual USB4 Type-C ports and a USB 20 Gbps front-panel header provide high-speed external connectivity. Wi-Fi 7 (802.11 be) and 5 Gbps LAN handle networking.

Questions about this item

How do I confirm the AI Cooling II and AI Networking II features are active after building with this combo?

Enter the UEFI BIOS and enable ASUS AI Advisor; the dashboard will show AI Cooling II fan curves and AI Networking II traffic optimisation once the Ryzen 9 9950X is detected.

What comes in the box and which items must be purchased separately?

The package includes the ROG STRIX X870E-H S MIKU motherboard, the Ryzen 9 9950X processor, I/O shield, SATA cables, M.2 screws and documentation; DDR5 memory, CPU cooler, graphics card, storage drives and power supply are not included.

Which M.2 slot should I use first for a PCIe 5.0 drive to get full speed with the 9950X?

Install the drive in the M.2_1 slot, which runs at PCIe 5.0 x4 directly from the Ryzen 9000 series CPU; the second PCIe 5.0 slot shares bandwidth with other devices.
