Compact powerhouse for multitasking

The Minisforum UM790 Pro barebone mini PC packs an AMD Ryzen 9 7940HS processor with 8 cores and 16 threads into a small black chassis. It ships with 32GB of DDR5 5600 memory in dual-channel configuration and a 512GB PCIe 4.0 SSD. Integrated AMD Radeon 780M graphics handle visual output across multiple displays. Windows 11 Pro comes pre-installed.

Sustained performance under load

Innovative liquid metal cooling works alongside active memory and SSD thermal solutions to maintain high clock speeds during extended workloads. The 19V DC power adapter supplies stable energy for continuous operation. Dual-channel DDR5 bandwidth and PCIe 4.0 storage throughput prevent bottlenecks when processing large datasets or rendering complex scenes over long periods.

Four-display connectivity decides fit

Dual HDMI 2.1 ports and dual USB4 ports enable up to four simultaneous 8K 60Hz outputs for expansive workstation setups. Buyers who need more than four external monitors or require internal expansion slots beyond the two M.2 2280 bays should consider alternative form factors. The fixed 32GB memory configuration also limits users who want to populate slots with their own modules.

Questions about this item

How loud and hot does the liquid-metal-cooled Ryzen 9 7940HS get when running all day?

The UM790 Pro uses liquid metal on the CPU plus active memory and SSD cooling to sustain high performance quietly during extended workloads.

Which DDR5 SODIMM modules and M.2 2280 PCIe 4.0 SSDs must I supply to complete this barebone system?

You need to add DDR5 5600 SODIMM sticks up to 64 GB total and one or two M.2 2280 PCIe 4.0 SSDs; the board has two slots for each.

Can the dual HDMI 2.1 and dual USB4 ports drive my older 1080p monitors and legacy USB-A peripherals at the same time?

Yes, the two HDMI 2.1 and two USB4 outputs support up to four displays simultaneously, and four USB 3.2 Gen 2 Type-A ports handle legacy devices.
