Purpose-built barebone

The ASUS NUC 14 Essential RNUC14MNK250000U is a 0.56L mini PC barebone kit built around the Intel Processor N250. It targets buyers who want a compact, low-power platform for office work, media playback or light content creation and who prefer to add their own DDR5 memory and M.2 storage.

Installation notes

The chassis opens easily for access to the single 262-pin SO-DIMM slot and the single M.2 2280/2242 socket. Only one DDR5-4800 module up to 16 GB can be fitted, and the M.2 slot accepts either a PCIe 3.0 x4 NVMe or a SATA SSD between 128 GB and 4 TB; mixing interface types is not possible because there is only one slot.

Interface limits

Triple 4K output at 60 Hz is available through DisplayPort 1.4, HDMI 2.1 and the front USB-C 3.2 Gen2 port, but the integrated Intel Graphics tops out at 4096 x 2160. The 2.5 GbE LAN port and Wi-Fi 6E AX211 wireless share the same Realtek and Intel controllers, so total throughput cannot exceed the 2.5 GbE ceiling.

Questions about this item

How do I verify the Intel N250 is running at its 1.25 GHz graphics clock after assembly?

The integrated Intel Graphics operate at 1.25 GHz with 32 Execution Units; once the system posts and drivers load, that frequency is reported in the graphics control panel.

What components are missing from the barebone kit and must be purchased separately?

The kit includes the chassis, board, 2.5 GbE LAN, Wi-Fi 6E AX211, Bluetooth 5.3 and VESA mount; you must add a DDR5-4800 SO-DIMM up to 16 GB and an M.2 2280/2242 NVMe or SATA SSD.

Which DDR5 SO-DIMM capacity should I choose for the single 262-pin slot?

The slot supports one DDR5-4800 module with a maximum of 16 GB; select an 8 GB or 16 GB stick depending on your workload.
