Compact AI mini PC with Core Ultra 9

The ASUS NUC 15 Pro+ NUC15CRSU9 is a 0.7L barebone system built around an Intel Core Ultra 9 285H processor and Intel Arc graphics. It ships with 16GB of DDR5 5600 memory and a 512GB drive, ready for AI workloads and multi-display productivity. Tool-free access simplifies future upgrades.

Replaces larger desktops for quiet multi-screen work

The slim chassis cuts noise by 1.2x compared to previous designs while supporting up to four 4K displays through two HDMI 2.1 ports and two Thunderbolt 4 connections. The jump is worth it when desk space is tight, silence matters, and 99 TOPS of AI performance accelerates local inference.

Check memory slots and display cables before

The board offers two 262-pin SO-DIMM slots with dual-channel support up to 96GB, so verify whether you plan to add a second module. Ensure your monitors accept HDMI 2.1 or DisplayPort 1.4 over Thunderbolt 4 for 4K at 60Hz. The 2.5GbE LAN port uses an Intel i226V controller.

Questions about this item

What size SO-DIMM slots does the NUC15CRSU9 use for memory upgrades?

The unit has two 262-pin SO-DIMM slots that accept DDR5 5600 modules up to 96 GB total in dual-channel mode.

How do I open the 0.7 L chassis to add RAM or storage without tools?

Remove the bottom cover by releasing the tool-free latch; the SO-DIMM slots and M.2 socket are then directly accessible.

Which component will need replacement first if the system runs heavy AI workloads continuously?

The integrated Arc graphics and Core Ultra 9 285H share the advanced thermal design; the fan is the only moving part and would be the first item to service.
