Compact Ryzen barebone

The minisforum DeskMini UM870 Slim is a new barebone mini PC built around an AMD Ryzen 7 8745H processor with 8 cores and 16 threads boosting to 4.9 GHz. It ships with 16 GB of DDR5 memory and a 1 TB PCIe 4.0 SSD. Integrated Radeon 780M graphics based on RDNA 3 architecture handle visual workloads without a discrete card. The system targets users who need a small-footprint desktop for multitasking, light content creation or casual gaming.

Expansion slots and I/O

Two SODIMM slots accept DDR5 modules up to 32 GB each, and a second PCIe 4.0 M.2 slot is open for additional storage. Video output comes from HDMI 2.1, DisplayPort and USB4, each able to drive an 8K 60 Hz panel, while a third display runs at 4K 60 Hz. A 2.5 GbE RJ45 port, WiFi 6E and Bluetooth 5.3 provide wired and wireless connectivity. Four USB ports round out the peripheral complement.

Sustained thermal behaviour

The slim chassis relies on an integrated cooling solution to manage the 8745H under prolonged load. During extended compile jobs or long gaming sessions the processor will throttle to stay within its thermal envelope, so peak boost clocks are not maintained indefinitely. Radeon 780M performance similarly settles to a stable level after the initial burst. Buyers expecting continuous maximum turbo across hours of heavy compute should consider a larger form factor.

商品問答

Does the Ryzen 7 8745H throttle under long, heavy workloads?

The processor has a 45 W base power and boosts to 4.9 GHz; sustained loads will be managed by the built-in cooling system.

How loud and hot does the UM870 Slim get during all-day operation?

The compact chassis uses an active cooler to keep the 8-core CPU and Radeon 780M graphics within thermal limits during continuous use.

What memory and storage are already installed so I know what to add?

It ships with 16 GB of DDR5 RAM and a 1 TB PCIe 4.0 SSD; two SODIMM slots support up to 32 GB each and a second SSD slot is available.
