The MINISFORUM UM780 XTX is a versatile mini PC powered by the AMD Ryzen 7 7840HS processor with Radeon 780M graphics.

Rating: 8.2/10 | Price: $599.00
OCuLink eGPU Support
The standout feature of the UM780 XTX is its OCuLink port, which provides a direct PCIe connection to an external GPU enclosure. This means you can add a full-size desktop graphics card for gaming, 3D rendering, or AI workloads — something virtually no other mini PC offers. The OCuLink connection has much lower latency and higher bandwidth than Thunderbolt eGPU solutions.
Performance
The Ryzen 7 7840HS with Radeon 780M handles everyday productivity, content creation, and 1080p gaming on its own. But the OCuLink port means you’re never limited by integrated graphics — add an RTX 4070 or RX 7800 XT in an eGPU enclosure and you have a machine that can handle 4K gaming and GPU-accelerated AI workloads.
