minisforum DeskMini UM870 Slim Ryzen 7 8745H 16GB 512GB barebone mini PC

Ready-to-run mini PC for compact workspaces

The minisforum DeskMini UM870 Slim arrives with an AMD Ryzen 7 8745H eight-core processor, 16 GB of DDR5-5600 memory and a 512 GB PCIe 4.0 SSD already installed. Integrated Radeon 780M graphics drive up to three displays, including 8K at 60 Hz over HDMI 2.1 and USB4. Wi-Fi 6E, Bluetooth 5.3 and a 2.5 GbE port handle networking in a silver chassis that fits on any desk.

Verify memory, storage

The system ships with two SODIMM slots populated to 16 GB total and supports up to 64 GB of DDR5-5600 in dual-channel mode. A single PCIe 4.0 M.2 slot holds the included 512 GB drive; a second PCIe 4.0 slot is free for expansion. Video outputs comprise one HDMI 2.1, one DisplayPort and one USB4 port — check that your monitors match these interfaces and that 8K@60 Hz is required, otherwise a simpler configuration may suffice.

Thermals noise and power in daily use

The 8-core Ryzen 7 8745H boosts to 4.9 GHz within a compact vapour-chamber cooler designed for sustained office and light creative workloads. Fan noise stays low during typical productivity tasks and rises only under prolonged multi-threaded loads. Power draw remains modest thanks to the mobile-class silicon, so a standard external power adapter is sufficient without needing a high-wattage supply.
