Ready-to-run Mini PC

The ASUS RNUC15CRKU7089CU is a compact desktop that ships with Windows 11 Pro installed and an Intel Core Ultra 7 255H processor at 2.00 GHz. It includes 32 GB of DDR5 memory and a 1 TB NVMe SSD, so it works straight from the box. Built-in Intel Arc 140T graphics handle everyday visual tasks and light creative work.

Simple setup with room to grow

Only the power adapter and an HDMI cable are required to start; the 120 W supply is included. Two Thunderbolt 4 ports and three USB 3.2 Gen 2 ports give plenty of peripheral bandwidth, while Wi-Fi 7 and 2.5 Gigabit Ethernet cover networking. Memory slots accept up to 96 GB DDR5 if workloads demand more capacity later.

Ideal for space-constrained professionals

Suits office workers, developers and digital-signage deployments that need a quiet, VESA-mountable system with modern I/O. Buyers who want discrete graphics performance, user-replaceable 2.5-inch drive bays or a chassis larger than 1.5 by 4.6 by 4.4 inches should look at a different form factor.

Questions about this item

How can I verify the Intel Core Ultra 7 255H is running at its 2.00GHz base frequency after setup?

Open Task Manager's Performance tab and select CPU to confirm the 2.00GHz base clock, or run Intel Processor Diagnostic Tool for a full validation of the Core Ultra 7 255H.

What comes in the box and what must I purchase separately for the RNUC15CRKU7089CU?

The package includes the NUC 15 Pro mini PC and its 120W power adapter; the 32GB DDR5 memory and 1TB NVMe SSD are already installed, so no extra parts are required for basic operation.

Which configuration should I choose if I need up to 96GB of DDR5 memory?

This model ships with 32GB DDR5 installed and supports a maximum of 96GB, so you can add two 32GB DDR5 SO-DIMMs later if your workload demands more capacity.
