MINISFORUM UM890 Pro Mini PC, AMD Ryzen 9 8945HS (up to 5.2GHz) Mini Computers

Awesome, powerful mini PC. Works best with Linux, and very capable as a server. This has plenty of power to handle multiple simultaneous transcoding operations, assuming you’re working with a client that supports AMD transcoding well. Capable of running multiple VMs simultaneously for extended periods of time. Runs silent, but packs a lot of punch.

This mini PC turned out to be a surprisingly powerful productivity machine. The hardware specs are excellent, and for my use, mainly office work, simply photo editing and streaming movies, it has more than enough power. I haven’t tried any demanding 3D games, so far it runs whisper quiet and I barely notice any fan noise. Windows 11 is pre-loaded and it’s ready to use out of box.There are a couple of downsides though. The BIOS is very barebones with only a handful of core options, which is fine for most people but a bit limiting if you like to tweak settings. The case is plastic with a metallic look, but it does feel a little cheap in person. The worst part for me is the power button LED, it’s ridiculously bright and distracting when the PC is on my desk. I ended up covering it with a piece of tape just to tone it down.Overall, the performance is outstanding and I don’t see myself worrying about upgrades for years to come.

This is one Mini-PC that didn’t boot up into the operating system or the BIOS. There was no HDMI signal or DP signal to the computer monitor/screen. The only thing that powered on was the LED power button. I should have assumed something was wrong with it when I discovered it was an opened box Mini-PC. There was no shrink wrap packaging to seal it for security or protection tampering. Plus the “LPN” license plate number sticker label on the back of the box was a clear indicator that it was a returned item.Prior to this purchase, I had one NAB9 that worked for 5 months then it failed. The second one failed after 4 months of use. My suggestion, buyer beware when there is ‘1 left in stock’, it could be a lemon.

I bought this device mainly for moonlight streaming. I can confirm that the HDMI 2.1 port is capable of doing 4k 120hz HDR VRR, as long as your cable and display are also adequate. Latency seems to be about as expected for the 6900hx.Apart from that, there’s not too much else to say. Looks wise it’s pretty good. The front side light flashes a bit too much for my liking, but that’s basically every PC nowadays, and easily fixed with some electrical tape. The fans are not loud and sound reasonable to me, though admittedly I have not pushed the system to its limits.Overall I can say that it does the job well.

The specs for the price is great. It is insane how much power we can get in these small mini PCs these days. It is very easy to add RAM and M.2 SSDs, although having the screws under the sticky rubber feet is annoying. If you have to open it a couple of times, they might lose some of their adherence at some point.Also, the built-in wireless/bluetooth card is a Mediatek one that doesn’t work well with Linux distros. It is easily replaceable for a more common Intel one though, but I wanted to point this out if you were buying this hoping to run Linux on it. You may need to buy a wifi dongle if you don’t want to swap the m.2 wifi card for an Intel one. Or go wired. Wifi should be fine on Windows though.Also note that it take some time to boot at first if you bought a barebone model and installed your own RAM and SSD. The BIOS is also a little bit confusing to me and not as feature-rich as I thought it would be. some features were puzzling me a bit at first but I ended up figuring it out.I also don’t know if I had a defective power supply or if the provided one is not sufficient under some particular circumstances, but mine was shutting down when running specific emulators or programs (and not necessarily the most power-hungry ones). Let me be clear, the PC was not crashing. It was the power supply that just stopped functioning in 100% reproducible manner in specific programs. Then the PC would never boot up again UNLESS I unplugged the power supply from the wall and plugged it back in. I assume this was “resetting” the power supply. Nevertheless, I bought a another (better) power supply, and the problem went away. And support from the manufacturer reimbursed me the cost, which was awesome on their part. Great service!But all that being said, this thing rock. I’m literally using this as a small gaming console, and I’m impressed at what it can run.I’d recommend easily to anyone who’s planning on running Windows on it. A little bit less for Linux users given the Mediatek wifi/bluetooth chipset might not be supported on all distros (was not working on the ones I tried).
