Compact barebone for custom builds

The ASUS NUC 15 Pro NUC15CRKU5 is a new 0.48L barebone mini PC built around an Intel Core Ultra 5 225H processor with 14 cores and Intel Arc Graphics. It ships without memory or storage so integrators can choose DDR5-5600 SO-DIMMs up to 96 GB across two slots and two NVMe SSDs in 2280 and 2242 form factors. The platform targets commercial deployments and compact workstations that need Intel vPro manageability.

Display and I/O limits

Quad 4K output is supported through dual HDMI 2.1 ports and a Thunderbolt 4 connection with DisplayPort 2.1 signalling. Wired networking tops out at 2.5 Gbps via the Intel i226V controller, while wireless uses Wi-Fi 7 and Bluetooth 5.4. The single Thunderbolt 4 port shares bandwidth with display traffic, so driving four panels simultaneously reduces available throughput for attached peripherals.

Compatibility checklist

Verify that your SO-DIMMs are 262-pin DDR5 modules rated for 5600 MT/s; other generations will not fit. Confirm both M.2 slots accept NVMe PCIe drives — one 2280 and one 2242 — and that your SSDs match those lengths. Ensure your operating system supports Intel vPro and Arc Graphics drivers for full feature enablement.

Questions about this item

Which DDR5 speed should I pick for the 262-pin SO-DIMM slots to reach the rated 96 GB maximum?

Install DDR5-5600 modules; the board runs them at that speed in dual-channel mode and supports up to 96 GB total across the two slots.

What does the 4.90 GHz boost clock on the 14-core Core Ultra 5 225H mean for everyday workloads?

The 4 P-cores can hit 4.90 GHz for bursty single-thread tasks while the 8 E-cores and 2 low-power E-cores handle background threads, keeping the system responsive under mixed loads.

How many 4K displays can I drive simultaneously over the Thunderbolt 4 and HDMI 2.1 ports?

Up to four 4K displays — two via the HDMI 2.1 ports and two more through the Thunderbolt 4 connection with DisplayPort 2.1 alt-mode.
