Core Ultra 7 255HIntel Arc 140T2x 2.5G LAN · TB4vPro · TAA

The ASRock Industrial NUC BOX-255H is a fanned industrial barebone mini PC built around the top-tier Intel Core Ultra 7 255H (Arrow Lake-H) processor with Intel Arc 140T graphics and an on-chip NPU, designed for demanding edge AI, digital signage and managed business deployments. Supplied under part number 90PXGDK0-P0EAY100 (EAN 4711420964136), it ships without memory, storage or an operating system — the CPU, Wi-Fi 6E module, 120W adapter and VESA bracket are included, while you add the DDR5 memory, M.2 NVMe SSD and OS. Typically in stock with fast delivery across Cyprus.

Barebone — what you need to add
To complete the build you will need: DDR5-6400 CSO-DIMM memory (2 slots, up to 96GB total / 48GB per module); storage — two M.2 Key M slots (PCIe Gen4 x4) plus a SATA3 port, with Intel VMD RAID 0/1; and an operating system (Windows 10 or 11). The Wi-Fi 6E + Bluetooth module, 120W AC adapter and VESA mounting bracket are already included.

Frequently Asked Questions

What do I need to add to the NUC BOX-255H before using it?
As a barebone it includes the Core Ultra 7 255H processor, cooling, Wi-Fi 6E module, 120W adapter and VESA bracket. You add DDR5-6400 CSO-DIMM memory (up to 96GB), one or more M.2 / SATA SSDs, and an operating system such as Windows 10 or 11.
How many displays can it drive at once?
Up to four. Two come from the rear HDMI 2.1 ports and two more from the USB4 (DisplayPort 2.1) and USB-C (DisplayPort 1.4a) outputs, all up to 4K at 60Hz.
What is the difference between the NUC BOX-255H and NUC BOX-225H?
They share the same industrial chassis and ports. This model uses the faster Core Ultra 7 255H with Arc 140T graphics and a 120W adapter; the NUC BOX-225H uses the Core Ultra 5 225H with Arc 130T and a 90W adapter.
Does it support business management and secure procurement?
Yes. It offers Intel vPro Essentials for remote management, firmware TPM (Intel PTT) and TAA compliance for government and enterprise procurement, plus an on-chip NPU for local AI workloads.
Singular Expert Insight
The NUC BOX-255H is the flagship of ASRock’s Arrow Lake-H industrial minis: a fanned 0–40°C chassis with top-tier Core Ultra 7 performance, Arc 140T graphics, a local AI NPU, dual 2.5G LAN, vPro Essentials and TAA compliance — ideal for demanding edge AI, signage and managed fleets. Because it is a barebone, you fit only the DDR5 memory and NVMe SSD your project needs. If the Ultra 7 is more than you need, the NUC BOX-225H (Core Ultra 5 225H) is the value option.

Buyer’s Guide

Buy it if
You need a high-performance industrial edge-AI or signage mini with Arc 140T graphics, dual 2.5G LAN and vPro / TAA, and want to choose your own DDR5, SSD and OS.
Skip it if
You need a certified Copilot+ PC (40+ TOPS NPU) or just a basic office desktop — this is a higher-end industrial platform.
Also consider
The NUC BOX-225H (Core Ultra 5 225H, 90W) for a lower-cost build, or the slim NUCS BOX-255H where space is tight.
