MINISFORUM UM790 Pro Mini PC - Compact 4K Multi-Display Power

Our review of the MINISFORUM UM790 Pro finds a compact mini PC built for power users who need desktop-class performance in a small package. With an AMD Ryzen 9 7940HS and Radeon 780M graphics, it targets content creators, professionals who multitask, and anyone who wants to drive multiple high-resolution displays without a bulky tower. The most compelling reason to buy is raw sustained performance and modern display connectivity in a tiny chassis, delivering near-desktop responsiveness for editing, productivity and light gaming while remaining quiet and space-saving.

Key Features

• Processor: The Ryzen 9 7940HS with 8 cores and 16 threads provides strong multi-threaded performance for editing, compiling and heavy multitasking.
• Graphics: Radeon 780M based on RDNA 3 delivers solid integrated GPU performance for 4K video playback and casual to moderate gaming without a discrete card.
• Multi-monitor outputs: Two HDMI 4K@60Hz ports plus two USB4 ports (8K@60Hz) let you connect up to four displays for extended desktops or multi-app workflows.
• Memory and storage: Ships with 32GB DDR5 RAM and a 1TB PCIe 4.0 SSD, giving fast app load times and room for large media libraries with straightforward upgrade paths.
• Networking: A 2.5Gbps LAN port supports higher network throughput for fast file transfers and software router or firewall use cases.
• Boot and power features: Supports Auto Power On, PXE Boot, WOL and RTC Boot for flexible remote or business deployments.

Who It's For

This mini PC is best for creative professionals and power users who need a small footprint without sacrificing CPU and integrated GPU capability. If you work with high-resolution video, run multiple simultaneous productivity apps, or want to drive several monitors from one machine, the UM790 Pro is well suited.

It is less ideal for users who require a discrete GPU for high-end gaming or workstation-class GPU compute, or those who need an ultraportable laptop. Also, occasional users who only need basic web browsing and office apps may find the power and cost more than required.
