## Description

MINISFORUM UM870 Slim Mini PC AMD Ryzen 7 8745H 8C/16T Desktop Computer Barebone Without RAM/SSD/OS, HDMI/DP/USB4 8K@60Hz Output, 1X2.5G RJ45 Port, 4XUSB Port, Dual Band WiFi, AMD Radeon 780M Graphics

Review: Good - Wifi not supported on Linux. I knew that when buying, but a better wifi card would... be better. Works great for gitlab hosting, no noise.
Review: Great cooling, quiet, and powerful - I bought this to replace my 9th gen CPU laptop with GTX1060 MaxQ GPU. Because I bought the barebone model, I purchased 32GB Crucial DDR5 RAM and Hynix 1tb Platinum SSD. I cannot be happier because this mini PC satisfies all my needs and expectations. * Game Performance: One thing that was not clear to me was how well 780M would work with a game I sometimes play, World of Tanks. Comparing to 1060 MaxQ, 780M works better. Not sure about other games because that's the only one I play. * Cooling and noise level: These are beyond my expectations. It barely makes any sound even when I play the game. It gets warm on one side of the top after the game play. But, it cools down quickly and stays cool. In other uses, I didn't notice any heat-up. * Things to consider: When you need to install the OS by yourself, you may experience some issues. The wifi was not detected by Windows 11. I could not locate the correct drivers even after downloading them from Minisforum. And I could not locate any documents or manuals that are helpful. So, I used the trial version of Driver Easy to install all drivers. It solved all problems. (I believe other driver installation programs will work fine.) * One more: When you want to install or upgrade the SSD or RAM, you need to open the mini PC. The bottom legs are stickers. You can detach them carefully from the corner to the middle (bc that's where the bolts are and least sticky part). The rest is easy. Before my PC is arrived, Minisforum announced a higher version: UM890. It seems attractive because it has the Oculink connection that can be used for eGPU. In my opinion, if you are serious about using eGPU, you'd better consider a desktop. This miniPC is perfect for me for everyday use & work and some games.

### ⭐⭐⭐⭐ Excellent choice for mini pc
*by T***E on 31 January 2026*

Runs everything great. Using it in an arcade cabinet. Needed something inexpensive that could run retro games and works great. Bios isn’t very feature packed and the bright led isn’t dimmable, but those are minor annoyances.
