ASUS NUC 15 Pro+ Barebone with Core Ultra 9 285H

This barebone mini PC delivers a 16-core Intel Core Ultra 9 285H processor and integrated Intel Arc 140T graphics in a compact aluminium chassis. It targets developers and creators who need on-device AI acceleration up to 99 TOPS and prefer to choose their own DDR5 memory and NVMe storage.

Thermals noise and power draw

The processor runs at a 45 W base power with a 115 W maximum turbo and a 35 W minimum assured power level. The aluminium case acts as the primary heatsink for the CPU, GPU and NPU, so fan behaviour scales directly with sustained workload intensity. A 2.5 GbE controller and Wi-Fi 7 add minimal thermal load during typical network traffic.

Upgrade path and value

The system replaces larger desktops that lack integrated NPU acceleration or Thunderbolt 4 connectivity while fitting two SO-DIMM slots and dual M.2 slots (one Gen 5.0 x4, one Gen 4.0 x4). It is not suited for buyers who require discrete graphics headroom, more than 96 GB of memory, or additional PCIe expansion beyond the provided M.2 interfaces.

Questions about this item

How do I install memory in the two 262-pin SO-DIMM slots, and what step is often missed?

Insert both DDR5-5600 SO-DIMM or DDR5-6400 CSO-DIMM modules up to 48 GB each for 96 GB total; the Intel Arc 140T GPU only activates with both slots populated.

Which replaceable components will need attention over time?

The two DDR5 SO-DIMM modules and the two NVMe SSDs (one PCIe 5.0 x4 2280, one PCIe 4.0 x4 2242) are user-replaceable; the Core Ultra 9 285H processor is soldered in the BGA 2049 socket.

What thermal limit appears first when the 45 W base / 115 W turbo processor runs sustained loads?

The 115 W maximum turbo power ceiling is reached before the 35 W minimum assured power floor, so the 1.52 lb aluminum chassis must dissipate up to 115 W continuously.
