MINISFORUM Venus UM790 Pro Mini PC Barebone - Powerful Ryzen 9 Mini PC

In this review the MINISFORUM Venus UM790 Pro is presented as a compact, high-performance barebone mini PC best suited for users who want desktop-class power in a small footprint but plan to provide their own RAM, storage and operating system. The single biggest reason to consider it is the combination of an AMD Ryzen 9 7940HS CPU with integrated Radeon 780M graphics and advanced cooling, which together deliver sustained performance for gaming, content work and AI-assisted tasks while remaining quiet.

Key Features

• Processor: The AMD Ryzen 9 7940HS offers 8 cores and 16 threads with up to 5.2GHz burst speed, giving strong single-thread and multithread performance for demanding applications.
• Graphics: Integrated AMD Radeon 780M with a 2.8GHz graphic frequency provides capable GPU performance for 3D tasks and casual to moderate gaming without a discrete card.
• Memory and Storage: Dual-channel DDR5 5600 SODIMM support and two M.2 2280 PCIe 4.0 slots let users install up to 64GB of RAM and high-speed NVMe storage with RAID0 or RAID1 options for flexibility.
• Connectivity: Dual USB4 ports, four USB 3.2 ports, dual HDMI 2.1 outputs and 2.5Gbps RJ45 deliver modern connectivity for multi-monitor setups and fast wired networking.
• Cooling: The Cold Wave 2.0 liquid metal cooling with active memory and SSD cooling keeps temperatures lower and noise down, enabling the system to sustain higher performance.
• Wireless: Built-in WiFi 6E and Bluetooth 5.3 provide broader wireless bandwidth and low-latency device pairing for streaming and peripherals.

Who It's For

The UM790 Pro is ideal for enthusiasts, content creators and gamers who want a compact desktop with high CPU and integrated GPU performance and who are comfortable installing their own RAM and SSD and choosing an operating system. It also appeals to users who value quiet operation and modern IO such as USB4 and HDMI 2.1 for multi-monitor setups.

It is not for buyers who expect a ready-to-run out-of-the-box system with memory, storage or a preinstalled operating system, or for those who need a discrete high-end GPU inside the chassis; those users should seek a preconfigured desktop or a mini PC with included components.

Pros & Cons

Pros

• High-performance Ryzen 9 7940HS with strong integrated graphics in a small chassis.
• Flexible DDR5 and dual PCIe 4.0 M.2 storage options with RAID support for fast storage configurations.
• Modern connectivity including 2x USB4, 2x HDMI 2.1 and WiFi 6E for peripherals and multi-display use.
• Efficient Cold Wave 2.0 cooling keeps noise low while maintaining sustained performance.

Cons

• Barebone configuration means buyers must supply RAM, SSD and an OS before use.
• Some users reported mixed experience with WiFi connectivity, so wired networking may be needed for full reliability.
