Install Tip: Use a Phillips screwdriver to secure the M.2 drive with the supplied screw. No M.2 adapter required—standard 2280 form factor fits directly.
Power Supply
The UM890 Pro uses a 19V / 120W barrel connector power adapter (similar to older ThinkPad laptops). Power draw ranges from 15W idle to ~70W sustained gaming.
- Included Adapter: 120W 19V barrel connector.
- USB-C Power Delivery: NOT supported—this model requires the dedicated 19V barrel.
- Replacement Adapters: Search “19V 120W barrel laptop charger” on Amazon UK; most universal laptop chargers work, but verify pin compatibility.
Display & Docking
The UM890 Pro supports dual independent displays:
- HDMI 2.1: 4K@60Hz (ideal for gaming, streaming).
- USB-C DP 1.4: 4K@60Hz (alternative to HDMI).
Docking & Hub Options:
- USB-C Hub: UGREEN 10-in-1 or Anker PowerExpand (USB 3.1, HDMI, SD card, PD pass-through).
- Legacy Dock: Search for “19V powered USB-C dock” to dock and charge simultaneously.
- Multi-Monitor: Use HDMI + USB-C DP for independent 4K displays.
WiFi 6E & Bluetooth 5.2
WiFi 6E (802.11ax): ~1.2Gbps peak throughput in ideal conditions. Real-world: 300–600 Mbps depending on router and distance.
- 2.5GbE Ethernet: For maximum stability on office networks, use the wired ethernet port.
- Bluetooth 5.2: Excellent wireless peripheral support (keyboards, mice, headphones).
Upgradeability Score
9/10 — Exceptional. User-upgradeable RAM (up to 96GB DDR5), dual M.2 2280 slots, easily accessible bottom panel. One of the most future-proof mini PCs for the price.
FAQ
What’s the maximum RAM the UM890 Pro supports?
96GB (2x48GB DDR5-5600 SO-DIMM). Officially supported; some users report working with DDR5-6000 modules, but stick with DDR5-5600 for guaranteed compatibility.
Can I use PCIe 5.0 NVMe drives?
The UM890 Pro slots are PCIe 4.0. PCIe 5.0 drives work (backward compatible) but won’t benefit from the extra bandwidth—save the cost and buy PCIe 4.0.
Does it support external GPU docking?
No Thunderbolt port, so eGPU is not supported. The Ryzen 9 8945HS iGPU is sufficient for most gaming and video work.
What’s the idle power consumption?
~10–15W at idle, ~40–50W during light work (browsing, office), ~70W sustained gaming.
Can I upgrade the WiFi module?
The WiFi 6E module is soldered to the mainboard and cannot be replaced. However, 2.5GbE wired ethernet is available as a fallback.
