MINISFORUM UM890 Pro Barebone Mini PC - High-Performance 8K Quad

Our review of the MINISFORUM UM890 Pro finds it best suited to power users who need a compact desktop with strong CPU and integrated GPU performance. The single biggest reason to consider it is the combination of the AMD Ryzen 9 8945HS with an integrated AMD Radeon 780M and an NPU, which delivers desktop-class compute and graphics in a small chassis capable of driving multiple high-resolution displays. This review focuses on real-world multitasking, connectivity and thermal behavior rather than marketing claims.

Key Features

• Processor: The Ryzen 9 8945HS with 8 cores and 16 threads delivers fast single-threaded and multithreaded performance for productivity and gaming workloads.
• Integrated graphics: The AMD Radeon 780M runs at up to 2,800 MHz and handles 3D tasks and high-resolution video playback without a discrete GPU in many use cases.
• Memory expandability: Dual-channel DDR5 via a SODIMM slot supports up to 96 GB at up to 5600 MHz, letting users scale RAM for heavy multitasking and virtualization.
• Storage flexibility: Two removable M.2 2280 PCIe 4.0 SSD slots support up to 8 TB total, enabling very fast local storage and easy upgrades.
• Quad-display outputs: HDMI 2.1, DP 1.4 and dual USB4 ports allow up to 8K@60Hz or 4K@144Hz outputs across multiple monitors for content creation and multi-window workflows.
• Connectivity and peripherals: Dual 2.5G LAN ports, multiple USB3.2 Gen2 Type-A ports, OCuLink and USB4 PD options give broad wired connectivity for networks and docks.

Who It's For

The UM890 Pro is aimed at power users, compact workstation buyers and gamers who want near-desktop Ryzen 9 performance in a mini PC footprint, plus support for multiple high-resolution monitors. Creative professionals who rely on GPU-accelerated editors and developers who run VMs will appreciate the large RAM and fast storage capacity.

It is less suitable for someone who expects field serviceability like hot-swap drives or who needs a consumer plug-and-play streaming box; a few user reports indicate isolated reliability issues that suggest buyers who require a mission-critical always-on appliance should plan for backups or warranty support.

Pros & Cons

Pros

• Very strong CPU and integrated GPU performance for a mini PC, making it capable for gaming and productivity.
• Flexible memory and storage expansion with high-capacity DDR5 and two PCIe 4.0 M.2 slots for fast NVMe drives.
• Extensive ports including dual USB4, HDMI 2.1, DP 1.4 and dual 2.5G LAN for multi-monitor and network setups.
• Efficient cooling design that keeps noise relatively low under load.

Cons

• Not all users agree on long-term reliability; there are reports of devices failing after months, so warranty support matters.
• Does not support hot swapping of drives and OCuLink requires a specific M.2 slot, limiting some advanced configurations.
