ASUS NUC 12 Pro i5-1240P barebone mini PC

Ready-to-mount barebone with 12th Gen Core i5-1240P

The ASUS NUC 12 Pro ships as a barebone kit built around a 12-core Intel Core i5-1240P processor with Iris Xe graphics. It targets system integrators and enthusiasts who want to supply their own DDR4-3200 SODIMMs and storage. The 35 W TDP and VESA bracket make it suitable for always-on commercial deployments or compact home labs. Buyers who need a fully assembled unit with memory and an operating system pre-installed should look elsewhere.

Tool-less chassis opens for SODIMM

Removing the bottom cover gives immediate access to two SODIMM slots supporting dual-channel DDR4-3200 up to 64 GB, one M.2 22x80 key M slot for PCIe x4 Gen 4 NVMe, and one M.2 22x42 key B slot for PCIe x1 Gen 3 or SATA. The tight internal clearances mean tall heat-spreaders on memory modules can foul the lid; verify module height before purchase. No drive caddies or extra cables are included, so have the correct M.2 screws to hand.

Vapor-chamber cooler sustains 35 W without

Under continuous multi-threaded workloads the integrated vapor chamber keeps the 4.4 GHz P-core and 3.3 GHz E-core turbo frequencies stable within the 35 W envelope. Surface temperatures remain low enough for 24/7 operation in enclosed mounts. Short bursts can push higher frequencies, but sustained compute settles at the rated TDP with no audible fan ramp. The single 1 Gbps Ethernet and Wi-Fi 6E AX211 links stay responsive throughout extended transfers.
