Compact barebone for custom builds

The minisforum Venus UM790 Pro arrives as a barebone mini PC without memory, storage or an operating system, letting system integrators and enthusiasts choose their own DDR5 modules and PCIe 4.0 SSDs. An 8-core Ryzen 9 7940HS processor with a 5.2 GHz boost clock and integrated Radeon 780M graphics handles demanding workloads and modern titles in a footprint that fits behind a monitor.

Dual USB4 and HDMI 2.1 for flexible I/O

Two USB4 ports provide DisplayPort alternate mode and power delivery alongside two HDMI 2.1 outputs, enabling up to four simultaneous 4K or 8K displays. Front-facing USB 3.2 Gen2 Type-A ports, a 2.5 Gbps Ethernet jack and a Clear CMOS button keep daily connectivity and troubleshooting within easy reach. The Intel Killer AX1675 module delivers Wi-Fi 6E and Bluetooth 5.3 in a standard M.2 2230 slot.

Efficient cooling in a 19 V DC design

The included 19 V adapter powers the 8-core chip and RDNA 3 graphics without a bulky external brick, while the internal thermal solution keeps temperatures and fan noise low during sustained productivity or gaming sessions. Dual-channel DDR5 support up to 5600 MHz and two PCIe 4.0 x4 M.2 2280 slots maintain high throughput without adding significant heat load.

Questions about this item

What does the USB4 interface on the UM790 Pro support in practice?

The two USB4 ports provide DisplayPort alt mode and power delivery, allowing 8K video output and peripheral connectivity through a single cable.

What physical storage slots does the barebone provide for adding an SSD?

Two M.2 2280 slots wired for PCIe 4.0 x4 are available for user-installed solid-state drives.

How do I install memory in the UM790 Pro, and what step is often missed?

Insert two DDR5 5600 SODIMM modules into the dual-channel slots until they click; the common mistake is not seating both sticks fully, which prevents the system from posting.
