ASUS has introduced the ExpertCenter PN55 Mini PC, a compact desktop focused on AI workloads and business use. It is positioned as a Copilot+ PC and runs on AMD’s Ryzen AI 400 Series processors with an XDNA 2 NPU delivering up to 55 AI TOPS.

The lineup includes multiple processor options. At the top is the Ryzen AI 9 HX 470 with a 45W cTDP. Other options include Ryzen AI 9 465, Ryzen AI 7 PRO 450, Ryzen AI 7 450, Ryzen AI 7 445, Ryzen AI 5 PRO 440, Ryzen AI 5 435, and Ryzen AI 5 430, most with a 40W cTDP. Graphics are integrated and vary by configuration. The Ryzen AI 9 HX 470 uses Radeon 890M, the Ryzen AI 9 465 uses Radeon 880M, the Ryzen AI 7 PRO 450 and Ryzen AI 7 450 use Radeon 860M, and the remaining models use Radeon 840M graphics.
The system supports up to 96GB of DDR5 memory through two SO-DIMM slots running at 5600MHz, with configurations starting at 8GB, 16GB, or 32GB. Storage is handled by two M.2 2280 PCIe Gen4x4 slots, supporting NVMe SSDs from 256GB to 2TB. ASUS will also offer a kit version without pre-installed memory or storage.


ASUS is focusing on AI-assisted features supported by the NPU and CPU. These include live captions for multilingual meetings, AI-based image and content generation, and system-level recall for searching previously accessed files. A Copilot key and voice command support are included for interacting with these features.
Connectivity includes Wi-Fi 7 with the MT7925 module or Wi-Fi 6E with the MT7922 module, along with Bluetooth 5.4. Wired networking is handled by dual 2.5G LAN ports using the RTL8125BG controller. The system can drive up to four 4K displays through HDMI 2.1, two DisplayPort 1.4 outputs, and USB4 with DisplayPort 2.1 support and 40Gbps bandwidth.
Port selection is spread across the chassis. The front includes a power button, one USB 3.2 Gen2 Type-C port at 10Gbps, two USB 3.2 Gen2 Type-A ports at 10Gbps, and a 3.5mm audio jack. The rear includes one USB4 port with 100W power delivery input, one USB 3.2 Gen2 Type-A port, one USB 2.0 Type-A port, HDMI 2.1, two DisplayPort 1.4 ports, two 2.5G LAN ports, and a DC-in connector. A Kensington lock slot is placed on the side.
Security features include a fingerprint sensor on the chassis and support for fTPM 2.0 or an onboard TPM module. Select models also include AMD PRO technologies for hardware-level security and remote management.
The PN55 uses an aluminum chassis with a tool-less design for easy upgrades. It measures 130 x 130 x 34mm and weighs 530g. It also supports VESA mounting for fixed installations.
ASUS says the system meets MIL-STD-810H durability standards and is designed for continuous use in office setups, digital signage, and general workstation tasks.
