Minisforum is a brand that is quite well-regarded by folks who are passionate about SFF/Mini PCs. Their latest offering, the UM870 Slim, continues to uphold that tradition, but with a relatively affordable price. With dimensions of 130 mm x 127 mm x 50 mm, the UM870 Slim boasts a volume of just 0.82 liters, staying true to its "Slim" moniker.

The UM870 Slim is powered by a 54 W Ryzen 7 8745H APU rocking 8 Zen 4 cores and 16 threads. This APU is basically a Ryzen 7 8845HS, but without the AI capabilities made possible by the XDNA NPU. The aforementioned 0.82 liter chassis means that the UM870 Slim lacks the luxury of discrete graphics, and relies on the integrated Radeon 780M GPU instead. Unlike some of its competitors, the UM870 Slim misses out on OCuLink support, which would've allowed for significantly faster eGPU connections as compared to USB4.




Apart from that, the UM870 Slim boasts a generous selection of ports, which include an RJ-45 2.5 G Ethernet port, dual USB 2.0, dual USB 3.2 Type-A, HDMI 2.1, DisplayPort 1.4, an audio jack, and a single USB4 port. The dual SO-DIMM slots can accommodate up to 96 GB of DDR5-5600 memory, while storage requirements are handled by dual M.2 2280 NVMe SSD slots. Prices start from $344 for the barebones version, while the 32 GB memory and 1 TB SSD configuration commands a $529 price tag.

I don't get what they're doing with the front connectivity...
  • UM890 Pro: 2x USB-A, 1x USB-C
  • UM790 Pro: 0x USB-A, 2x USB-C
  • Now this one: 2x USB-A, 0x USB-C
Like wtf?

Thanks to the USB4 on back I guess.

Got one during black friday via Amazon for $441 USD with 32GB 5600Mhz & 1TB SSD, could use bit more ports but apart from that, great for the price.

Front USB-C might be better for charging mobile phones / tablets but let's be honest, everyone just uses a charger for that and almost every computer peripheral in practise most likely to be temporarily plugged into either the front (USB sticks, external HDD's, controllers) or permanently plugged into the rear (keyboard, mouse, printer, etc) are nearly all overwhelmingly USB-A. So they probably tried Rear = 2x USB-A + Front = USB-C in the past only to get feedback of how useless that is to want to copy one USB drive / stick to another without unplugging the keyboard & mouse / needing USB C-A adaptors hanging off the front each time...

The product website for choosing variant shows "NO OS&CPU&SSD". No CPU? Is this a typo?

Yeah I just saw that option on Minisforums website, makes no sense to me, has to be a major TYPO on their part, I'd contact them about that if you're interesting in the UM870 Slim, cause I don't know how the average consumer is going to solder on a 8745H APU chip lol.
