Compact barebone for custom builds

The ASUS ExpertCenter PN65 is a new mini-PC barebone that ships without memory or storage, letting integrators choose DDR5 SO-DIMMs and M.2 drives to match the workload. Its Intel Core Ultra 5 125H processor and integrated Arc graphics suit office productivity, digital signage and light content creation in space-constrained locations.

Dual-channel DDR5 up to 96 GB

Two 262-pin SO-DIMM slots accept DDR5 5600 modules in dual-channel mode for a maximum of 96 GB, which is the single figure that determines whether the platform can handle the intended multitasking or virtualisation load. Exceeding this capacity is not supported by the memory controller.

Tool-less access and VESA mounting

The chassis opens without tools for SO-DIMM and M.2 2280 installation, and a VESA bracket is included for behind-monitor mounting. Builders must supply a 2.5-inch SATA drive separately if the third storage bay is needed, and should verify that the chosen M.2 SSDs are PCIe Gen4 x4 NVMe models to match the two keyed slots.

Questions about this item

How much RAM can the Core Ultra 5 125H actually use in this barebone?

The board accepts two 262-pin SO-DIMMs and supports up to 96 GB of DDR5 running at 5600 MHz in dual-channel mode.

What does the 2.5 Gbps LAN port limit in real use?

The Intel i226V controller caps wired throughput at 2.5 Gbps, so file transfers and backups cannot exceed that speed even on a faster switch.

Which drive bays and M.2 slots are available for adding storage?

You can install two M.2 2280 PCIe Gen4 x4 NVMe SSDs and one 2.5-inch SATA drive using the 6.0 Gb/s SATA connector.
