This is possibly the cheapest mini PC that can use an external GPU, thanks to its OCuLink and USB 4 ports — GMK K12 supports 128GB DDR5 and 24TB SSD storage

• GMK K12 uses OCuLink and USB4 to make eGPU support completely plug-and-play
• Ryzen 7 H 255 pushes 70W under load, rare in palm-sized budget mini PCs
• Triple M.2 SSD slots make the K12 unusually capable of handling massive storage arrays

GMK has launched the K12, a mini PC priced at 2,099 yuan (approximately $292), designed for users seeking a compact yet expandable system.

Unlike typical budget systems, the K12 supports both OCuLink and USB4, making external GPU connectivity a practical reality without modifying internal components.

Powered by AMD’s Ryzen 7 H 255, the GMK K12 features an 8-core, 16-thread Zen 4 processor with clock speeds ranging from 3.8GHz to 4.9GHz.
