ASUS NUC 14 Essential Core 3 N355 barebone

This compact barebone mini PC ships with an Intel Core 3 N355 processor at 15 W TDP, 16 GB of DDR5-4800 memory and a 512 GB NVMe SSD. It is aimed at office workers, digital-signage deployments and home users who need a quiet, VESA-mountable system ready to run productivity apps out of the box.

Who should consider this and who should not

The single SO-DIMM slot is factory-filled to the 16 GB maximum, so buyers who want more memory must look elsewhere. The two M.2 slots accept one 2280 NVMe or SATA drive and one 2242 SATA drive, limiting total internal storage to two devices. Triple display output via DisplayPort, HDMI and USB-C suits multi-monitor desks, but the integrated Intel Graphics cannot drive demanding 3D workloads.

Storage expansion decided by M.2 slot layout

Slot one supports 128 GB to 2 TB M.2 2280 NVMe PCIe 3.0 x4 or SATA SSDs, while slot two takes 128 GB to 2 TB M.2 2242 SATA SSDs only. This fixed combination determines whether the platform can meet a given capacity or performance target without external enclosures.

Questions about this item

How loud and hot does the 15 W Intel Core 3 N355 get when the mini PC runs 24/7?

The CPU has a 15 W TDP, so the cooling system is designed for low continuous heat output and quiet fan operation during all-day use.

Which display cables must I already own to use the triple-display outputs on this unit?

You need cables for DisplayPort, HDMI and USB Type-C with DisplayPort Alt Mode to drive three monitors simultaneously.

Will my existing 2.5 GbE switch and Wi-Fi 6E router work at full speed with the Realtek RTL8125BG-CG LAN and AX211 wireless?

Yes, the 2.5 GbE port and Wi-Fi 6E AX211 module both support the maximum speeds of your current 2.5 GbE switch and Wi-Fi 6E router.
