MINISFORUM DeskMini UM790 Pro Mini PC - Compact 8K-capable Mini PC

In this review of the MINISFORUM DeskMini UM790 Pro Mini PC, the bottom line is simple: it is for users who need near-desktop CPU and GPU power in a very compact chassis. The UM790 Pro combines a Ryzen 9 7940HS class processor built on a 4nm Zen 4 design with AMD Radeon 780M graphics, delivering strong single-core and integrated GPU performance for productivity, light content creation and 1080p gaming. The single biggest reason to buy is its blend of modern CPU architecture and versatile video outputs that support multi-monitor 4K and even 8K displays via USB4.

Key Features

• Ryzen 9 7940HS class CPU: Delivers high single-core speeds with a 4.0GHz base and up to 5.2GHz boost for fast application responsiveness.
• AMD Radeon 780M Graphics: Built on RDNA 3 ideas to provide surprisingly capable integrated graphics for high-frame-rate 1080p gaming and accelerated content tasks.
• Multiple high-resolution outputs: Two HDMI ports (4K@60Hz) and two USB4 ports (8K@60Hz) allow flexible multi-monitor setups and single-cable display options.
• 2.5Gbps Ethernet: A 2500Mbps LAN port expands networking possibilities for fast wired transfers, software router projects or low-latency work on local networks.
• Barebones flexibility: This is a barebones unit without RAM or SSD included, so users can choose memory and storage to match their performance needs and budget.
• Compact package: Includes HDMI cable, VESA mount and power adapter so the mini PC can be desk- or monitor-mounted quickly.

Who It's For

The UM790 Pro is best for power users who want a small form factor PC with modern CPU and integrated GPU performance: developers running Linux, professionals who need multi-monitor 4K output, and gamers who play at 1080p and value a quiet compact system. The barebones format also appeals to builders who prefer to select their own RAM and NVMe storage for specific workloads.

Users who should look elsewhere include those who want a ready-to-run system with preinstalled RAM and storage, or people who need the absolute highest discrete GPU performance for 4K gaming. Also consider other options if long-term serviceability or redundant cooling is a priority, since a few customers reported mixed experiences with fan longevity.

Pros & Cons

Pros

• Excellent processing speed and modern Zen 4 single-core improvements make everyday tasks and compiling brisk.
• Integrated Radeon 780M provides far better graphics than older iGPU generations for gaming and content work.
• Versatile video outputs including USB4 8K support enable flexible multi-monitor and high-resolution workflows.
• Small footprint and included VESA mount make it easy to tuck behind a monitor or fit on a crowded desk.

Cons

• Sold as a barebones unit, so buyers must add RAM and an SSD separately before use.
• Some customers reported mixed reliability with fan hardware, so occasional thermal or longevity concerns may arise.

Our Verdict

The MINISFORUM DeskMini UM790 Pro is a strong choice for users who need modern CPU and integrated GPU performance in a compact chassis and prefer to assemble RAM and storage themselves. Its multiple high-resolution outputs and 2.5Gbps networking offer excellent value for workstation tasks, light gaming and multi-monitor setups, though buyers should account for the extra cost of memory and storage and be mindful of occasional fan reliability reports.

Frequently Asked Questions

Does it include RAM and SSD?
No, this is the barebones version and ships without RAM or SSD, so you must install memory and storage yourself.

Can it drive multiple 4K displays?
Yes, the unit has two HDMI ports at 4K@60Hz and two USB4 ports capable of 8K@60Hz, allowing flexible multi-monitor setups.

Is it good for gaming?
It handles 1080p and many esports titles well thanks to the Radeon 780M, but serious 4K gaming will benefit from a discrete GPU instead.
