Purpose-built barebone

The ASUS NUC 15 Pro RNUC15CRHU70000U is a compact barebone mini PC built around the Intel Core Ultra 7 255H processor with integrated Intel Arc 140T graphics. It targets developers, IT managers and edge-computing deployments that need AI-ready compute in a 0.7 L chassis. Buyers who require discrete graphics or multiple full-size expansion slots should look elsewhere.

Memory and storage headroom

Two 262-pin SO-DIMM slots accept DDR5-5600 or CSO-DIMM DDR5-6400 modules up to 96 GB total, giving ample headroom for heavy multitasking and local inference workloads. Storage uses one M.2 2280 PCIe 5.0 NVMe slot and one M.2 2242 PCIe 4.0 NVMe slot; no drives are included, so capacity is limited only by the modules you install.

Interface practical limits

Wired networking tops out at 2.5 Gbps via the Intel i226V controller. Wireless uses Wi-Fi 7 (802.11be) with Bluetooth 5.4 for high-density environments. The integrated Arc 140T GPU supports DirectX 12.2, OpenGL 4.6 and OpenCL 3.0, but lacks the memory bandwidth of discrete cards for sustained 3D rendering.

Questions about this item

Will the Intel Core Ultra 7 255H work with my existing DDR4 memory modules?

No. This unit only accepts SO-DIMM DDR5-5600 MHz or CSO-DIMM DDR5-6400 MHz memory. DDR4 modules are physically and electrically incompatible.

How can I verify the Intel Arc 140T GPU is active after I install memory and storage?

Open Device Manager and confirm the display adapter lists Intel Arc 140T GPU without error codes.

What components come in the box and what must I purchase separately?

The barebone includes the chassis, motherboard with soldered Intel Core Ultra 7 255H, a US power cord and an Intel i226V 2.5Gbps LAN port. You must buy SO-DIMM DDR5 memory and M.2 NVMe SSDs separately.
