UM890 Pro Mini PC 64GB DDR5 1TB - High-Performance 8K Mini PC

In this review the UM890 Pro Mini PC is judged as a compact desktop for power users who need desktop-level CPU and GPU performance in a tiny footprint. The biggest reason to buy is its combination of an AMD Ryzen 9 8945HS with the AMD Radeon 780M graphics and a large preinstalled memory and storage configuration, which delivers snappy general computing, creative work in Photoshop and Lightroom, and competent modern gaming without a bulky tower.

Key Features

• Processor: The Ryzen 9 8945HS with 8 cores and 16 threads provides strong multithreaded performance and high singlecore boost up to 5.2GHz for demanding applications.
• Graphics: The integrated AMD Radeon 780M based on RDNA 3 delivers significantly improved GPU performance suitable for nextgeneration efficient gaming and content playback.
• Memory & Storage: Ships with 64GB DDR5 and a 1TB PCIe 4.0 SSD, giving fast application loading, smooth multitasking, and ample room for large photo and media libraries.
• Display Outputs: Multiple highresolution outputs including USB4 and HDMI allow support for 4K and 8K displays, expanding desktop space for editing or multimonitor productivity.
• Networking: Two 2.5Gbps RJ45 LAN ports enable higher throughput and advanced routing or firewall setups for power users and small servers.
• OCuLink Expandability: An OCulink port offers an external PCIe4.0 x4 connection for future add-on options such as an external GPU enclosure or highspeed peripherals.

Who It's For

The UM890 Pro is aimed at creators and power users who need a small desktop that can handle photo editing, multitasking, and moderate gaming without a large case. Its 64GB DDR5 memory and 1TB PCIe 4.0 SSD make it well suited to photographers, streamers, and professionals who value space savings and quiet operation.

It is less appropriate for users who require hotswappable external GPU setups, or who need a full desktop tower with abundant internal expansion bays. Also, buyers who depend on a particular external power setup should check reliability reports and warranty options before purchase.

Pros & Cons

Pros

• Excellent processing power from the Ryzen 9 8945HS for creative and productivity workloads.
• Strong integrated Radeon 780M graphics for modern gaming and highresolution display support.
• Large preinstalled 64GB DDR5 and 1TB PCIe 4.0 SSD for fast multitasking and storage performance.
• Two 2.5Gbps LAN ports and versatile video outputs improve connectivity and multidisplay setups.

Cons

• Some users have reported power supply issues; verify support options and monitor reliability.
• OCuLink is non hotswappable and requires an internal M.2 to use external PCIe, limiting plugandplay expansion.

Specifications

Our Verdict

The UM890 Pro is a compact but powerful mini PC that delivers desktop class CPU and GPU performance while occupying minimal desk space. It represents good value for users who need strong multitasking, photo editing capability, and modern gaming support, provided they accept a couple of practical limits around external expansion and reported power supply reliability.
