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.

Questions about this item

Does the box include the DDR5-5600 SODIMM modules and 512GB PCIe 4.0 SSD, or must I buy them separately?

The unit ships with 16 GB of DDR5-5600 memory and a 512 GB PCIe 4.0 SSD already installed, so no extra purchase is needed to start working.

Should I choose the 16 GB configuration or plan to fill both slots up to 64 GB?

The 16 GB kit occupies one of two SODIMM slots; adding a matching 16 GB or 32 GB module enables dual-channel mode and raises the ceiling to 64 GB total.

What does the 4.9 GHz boost clock mean for everyday workloads on the Ryzen 7 8745H?

The 8-core processor can hit 4.9 GHz on short bursts, giving snappy single-thread response for office apps and light content creation while the Radeon 780M handles 4K video and casual gaming.
