Mini PCs have quietly become one of the best value categories in all of PC hardware, and few machines illustrate that better than the Minisforum UM870 Slim. For around $379, you get an 8-core, 16-thread Ryzen 7 8745H (a Hawk Point APU with Radeon 780M integrated graphics), DDR5 memory, dual M.2 storage, and a chassis small enough to hide behind a monitor. That’s a staggering amount of compute per dollar — and it’s exactly the kind of machine that makes a killer homelab node, a silent HTPC, or a compact daily driver.
But mini PCs from Chinese vendors come with tradeoffs, and the UM870 Slim is no exception. In this review we’ll break down the real specs, how it stacks up against name-brand alternatives like the Intel NUC and Geekom, and whether it deserves a spot on your desk or in your rack.
The headline here is the Ryzen 7 8745H. This is essentially a rebadged Ryzen 7 8845HS without the NPU, which means you get the same 8 Zen 4 cores and Radeon 780M graphics that power laptops costing twice as much. For productivity, light gaming, and virtualization, it’s genuinely excellent.
In Cinebench R23, the UM870 Slim’s 8745H typically scores around 17,000–18,000 multi-core and roughly 1,750 single-core when the 45W TDP is fully unlocked. That’s comparable to a desktop Ryzen 5 7600 in multi-threaded workloads — in a box the size of a paperback book. Single-threaded performance is strong enough that everyday tasks feel instant.
The Radeon 780M iGPU is the real story for anyone eyeing this as a light gaming or media machine. Expect:
For a homelab, the 8 cores and 16 threads are a gift. Running Proxmox with a handful of VMs, Docker containers, and a media server is well within reach, and the 2.5GbE port plus Wi-Fi 6E keeps networking flexible. The dual M.2 slots mean you can run a fast NVMe boot drive alongside a big storage drive without an external enclosure.
The “Slim” in the name refers to the lower-profile chassis, and Minisforum has tuned the cooling accordingly. Under sustained load the 8745H will hold roughly 45W before throttling, and fan noise is audible but not obnoxious — think “laptop under load” rather than “leaf blower.” Idle noise is essentially inaudible. If you need maximum sustained performance, the standard (non-Slim) UM870 with a taller cooler is worth considering, but for most users the Slim’s balance is spot-on.
This is where the UM870 Slim’s value really shines. Let’s line it up against the obvious competition:
In short: if you want the same class of CPU from a big-name brand, you’re paying a $150–250 premium. The UM870 Slim trades brand prestige and local warranty convenience for raw value — a trade many builders are happy to make.
Yes — if you know what you’re getting into. The Minisforum UM870 Slim is one of the best-value mini PCs on the market right now. At ~$379 barebone (or ~$450–480 configured), it delivers desktop-class multi-core performance, genuinely capable integrated graphics, and enough I/O to serve as a homelab node, a living-room media PC, or a compact workstation. Nothing from Intel, Apple, or the big OEMs comes close on price-per-core.
Skip it if you need enterprise-grade warranty support, an NPU for local AI acceleration, or maximum sustained performance under all-core loads — in those cases, spend up on the full-size UM870, a Geekom, or a name-brand NUC. But for the value-focused builder who’s comfortable with a barebone setup and an overseas warranty, the UM870 Slim is a no-brainer.
You can pick up the UM870 Slim on AliExpress, but seller selection matters. Follow these rules to avoid headaches:
Expect to pay ~$379 for barebone or ~$450–480 for a 16GB/512GB bundle. Prices fluctuate with coupons and seasonal sales (11.11, Black Friday), so set a price alert and pounce when it dips.
