GMKtec NucBox K11 (Ryzen 9 8945HS)

The NucBox K11 is GMKtec's Ryzen 9 mini PC: an 8-core Zen 4 Ryzen 9 8945HS with Radeon 780M graphics in a 132 x 125 x 58 mm case cooled by twin fans. It takes two DDR5-5600 SO-DIMMs up to 96 GB and two PCIe 4.0 NVMe SSDs. Connectivity is strong: two Intel I226-V 2.5 GbE ports, two full-function 40 Gbps USB4 ports, and an OCuLink PCIe 4.0 x4 port for an external GPU dock. Intel NICs make it easier to run VMware ESXi than Realtek-based minis, and the OCuLink port lets it grow into a real gaming machine later. It is GMKtec's top AMD option short of its Ryzen AI and Strix Halo models, and it runs from a 120 W brick.
