ASUS NUC 15 Performance barebone kit

This ASUS NUC 15 Performance barebone kit arrives with an Intel Core Ultra 9 275HX processor and an NVIDIA GeForce RTX 5070 mobile GPU with 8GB GDDR7 already installed. It targets creators and professionals who need strong AI and graphics performance in a compact 3-litre chassis. Buyers who want a fully assembled system or a lower-power office unit should look elsewhere.

DDR5 6400 dual-channel memory

The board provides two 262-pin SO-DIMM slots supporting DDR5 6400 up to 96GB total. Storage uses one M.2 2280 PCIe Gen4x4 slot and one M.2 2280 PCIe Gen5x4 slot, each accepting 128GB to 4TB NVMe drives. No memory or drives are included, so the builder must supply both.

Toolless chassis access and cooling constraints

The toolless design opens quickly for SO-DIMM and M.2 installation, while the QuietFlow system uses three fans and dual vapor chambers to manage thermals. The compact 282.4mm x 187.7mm x 56.5mm footprint (bottom 146mm) limits airflow space, so high sustained loads may throttle if ventilation is restricted.
