Ready-to-build mini PC with Ryzen AI 5 340

The ASUS ExpertCenter PN54 barebone arrives with a six-core AMD Ryzen AI 5 340 processor and integrated Radeon 840M graphics. It supports up to 64 GB of DDR5 5600 memory across two SO-DIMM slots and provides two M.2 2280 PCIe Gen4x4 bays for NVMe storage. Wi-Fi 7 and Bluetooth 5.4 are integrated alongside dual 2.5 Gbps LAN ports.

Check memory, storage and power before ordering

No RAM or SSDs are included, so you must supply two DDR5 5600 SO-DIMM modules and up to two NVMe drives in the 256 GB to 2 TB range. The 262-pin slots accept standard notebook memory only. A compatible USB-C power adapter with Power Delivery input is required because the unit does not ship with an external power supply.

Toolless chassis and Copilot+ readiness change

The 0.6 L slim case opens without tools, letting you install memory and storage in seconds. The AMD XDNA2 NPU delivers up to 50 TOPS for on-device AI workloads and enables the Copilot+ PC feature set. Front USB 3.2 Gen2 Type-C with DisplayPort 1.4 and rear USB4 Type-C with DisplayPort 1.4 and PD-in support up to four 4K displays.

Questions about this item

Does the barebone include RAM and SSD, or do I need to buy them separately?

The unit ships with no memory and no storage installed. You must add two DDR5 5600 SO-DIMMs up to 64 GB total and one or two M.2 2280 PCIe Gen4x4 NVMe SSDs from 256 GB to 2 TB each.

How do I choose between different memory capacities for the two SO-DIMM slots?

Install two identical DDR5 5600 modules for dual-channel operation. The board supports up to 64 GB total, so select a matched pair that adds up to your target capacity.

What does the 50 TOPS NPU figure mean when the mini PC is running Windows Copilot+ features?

The XDNA2 NPU delivers up to 50 TOPS of AI throughput, enabling on-device Copilot+ experiences such as live captions, recall and image generation without cloud latency.
