ASRock Industrial NUC BOX-255H Intel Core Ultra 7 255H NUC PC with Arc 140T Graphics and Dual 2.5GbE

Security monitoring and digital signage often need a capable graphics engine and room for local recordings or content, in a small unit that sits behind a screen. The ASRock Industrial NUC BOX-255H is the Core Ultra 7 255H model of the NUC Ultra 200 BOX Series series, a fanned NUC PC with Intel Arc 140T graphics, Wi-Fi 6E and dual 2.5GbE, plus a SATA bay alongside two NVMe sockets.

The Core Ultra 7 255H is an Arrow Lake-H processor with 16 cores and Intel Arc 140T graphics. Two SO-DIMM sockets take dual-channel DDR5 6400 memory up to 96 GB. LAN1 supports Intel vPro Essentials, security comes from firmware TPM (Intel PTT), and the NUC BOX-255H supports Windows 11 and Linux, with a watchdog timer for unattended sites.

Storage combines two four-lane PCIe Gen4 M.2 M key sockets with a SATA 6 Gb/s port for an internal drive. Intel VMD RAID 0/1 works across the M.2 pair. Four displays run from two HDMI 2.1 outputs at up to 4K, DisplayPort 2.1 over the USB4/Thunderbolt 4 port and DisplayPort 1.4a over a second USB-C port. Three USB 3.2 Gen2 Type-A ports, two Intel 2.5GbE ports (I226LM and I226V) and a headphone and microphone jack complete the I/O, and a Wi-Fi 6E and Bluetooth 5.3 module comes fitted in the M.2 E key socket.

Power is 12 to 24 V DC through a DC jack, with AT or ATX power-on modes and a 19 V, 120 W adapter in the box. The fanned NUC is rated from 0 °C to 40 °C, stores from -40 °C to 85 °C and handles 5 to 90% non-condensing humidity, and it carries CE and FCC marks. A VESA bracket is included. We supply the NUC BOX-255H configured and tested, with memory, NVMe and SATA storage and the Windows 11 or Linux image fitted alongside the Wi-Fi 6E module. The NUC BOX-225H uses a 14-core Core Ultra 5 225H in the same housing, and the iBOX-255H puts this processor in a fanless housing with a COM port.
