ASUS ROG NUC (2025) RNUC15JNK9X489AU mini PC Intel Core Ultra 9 275HX RTX 5070 32GB DDR5 1TB NVMe

Gaming mini PC for compact high-performance builds

The ASUS ROG NUC (2025) RNUC15JNK9X489AU packs an Intel Core Ultra 9 275HX 24-core processor and an NVIDIA GeForce RTX 5070 mobile GPU with 8 GB GDDR7 into a 3-litre chassis. It ships with 32 GB DDR5-6400 memory and a 1 TB PCIe Gen4 NVMe SSD, targeting gamers and creators who need desktop-class power in a footprint smaller than most consoles.

Tool-free upgrades with thumb-screw access

Removing the top panel requires only the integrated thumb screws, exposing two CSO-DIMM slots and an M.2 2280 slot for memory or storage expansion. The tight internal layout means longer GPUs cannot be added, and the 330 W external adapter limits total system power, so high-wattage components are not supported.

Triple-fan vapour-chamber cooling under sustained

Three fans and dual vapour chambers keep the 275HX and RTX 5070 within thermal limits during extended gaming or render sessions, while acoustic output stays low enough for living-room use. Surface temperatures rise noticeably after prolonged maximum load, so adequate ventilation around the unit remains important.
