Ready-to-run mini PC for creators and multitaskers

The MINISFORUM UM790 Pro arrives with an AMD Ryzen 9 7940HS processor, 32 GB of DDR5 memory and a 1 TB PCIe 4.0 SSD already installed. Windows 11 Home is pre-loaded so the system boots straight to the desktop. It targets users who want high performance in a compact chassis without assembling parts themselves.

Four-display output limited by port bandwidth

Two HDMI 2.1 ports drive 4K at 60 Hz while two USB4 ports support 8K at 60 Hz, enabling four simultaneous screens. The 2.5 Gbps Ethernet and Wi-Fi 6E with Bluetooth 5.3 provide wired and wireless connectivity. Total display count and resolution are constrained by the available video outputs and their rated refresh rates.

64 GB DDR5 ceiling decides upgrade path

Two SODIMM slots run dual-channel DDR5 at 5600 MHz and accept a maximum of 64 GB. Buyers who need more than 64 GB of system memory must choose a different platform. The installed 32 GB leaves two slots populated, so expanding means replacing modules rather than adding to empty sockets.

Questions about this item

Should I pick the 32 GB DDR5 model or add another 32 GB stick to reach 64 GB?

The unit ships with 32 GB of DDR5-5600 in dual-channel mode across two SODIMM slots. The board supports up to 64 GB, so adding a matching 32 GB module will double capacity while keeping dual-channel performance.

What does the Ryzen 9 7940HS boost clock of 5.2 GHz deliver in daily workloads?

The 8-core Zen 4 processor runs at a 4.0 GHz base and can boost to 5.2 GHz, giving strong single-thread speed for snappy OS response, fast compile times and smooth multitasking in Windows 11 Home.

How do the two USB4 ports and two HDMI 2.1 ports limit display resolutions?

Each USB4 port supports 8K at 60 Hz, while each HDMI 2.1 port handles 4K at 60 Hz. All four outputs can run simultaneously for a quad-monitor setup.
