UM890 Pro Mini PC AMD Ryzen 9 8945HS(8C/16T, up to 5.2GHz) 64GB DDR5 1TB PCIe4.0 SSD, 2xUSB4(PD 8K)|1xHDMI|1xDP Four Outputs, 2x RJ45, BT5.2 4xUSB3.2 AMD Radeon 780M Graphics Micro Computer

I recently purchased a 14" HP Spectra x360 (32 Gb memory), which I love for travel, but found that it's performance was getting bogged down due to overheating when running multiple screens with half a dozen workspaces active and 50-60 open tabs. Based on a number of reviews, decided to try this Minisforum as my main computer when not travelling. Out of the box, the machine ran the usual updates, then synched my microsoft settings and workspaces. It has, since, been running the multiple workspaces and tabs - some of which are running mapping applications - with nary a whimper. Barely warm, completely silent and noticeably faster under heavy workload than my beloved Spectra, this is an impressive little machine. Time will tell how it will age, but for the moment, I am impressed. Loved this little computer until the moment it failed. Just died - no warning. Review of several sources suggests the power supply may have failed. Returned unit.

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.

I am extremely pleased beyond expectations with this remarkable mini pc. The UM 890 performs as well as I'm used to with my DIY desktop with a 12700k and DDR4 RAM. Plus I get the advantage of so much freedom of space. The best part is the great support from Minisforum prior to receiving and during the setup of the unit. Great advice and guidance in a friendly personal manner. The unit itself has a neat magnetic cover to avoid having to screw and unscrew when adding or upgrading Ram or drives. They included the occulink adapter which I might use later on. Right now I'm getting perfect 4k 144 Hz display on and M32u 32" monitor better looking then the 1080 Ti I was used to. Thank you Minisforum for a great product and service. I look forward to more.

I think it could have been a bit cheaper. I can confirm I can run three 4k displays @60Hz. The USB4 ports support 4k/60hz. The Display Port does, too. I could not get the HDMI to do 60Hz, only got 30Hz, but maybe it was the cable Update: DOES not support HDMI 2.0, only 1.4. Therefore the seller description is NOT correct. Max refresh for a 4k screen is only 30Hz.

Update 7/4/2021 TPM 2.0 - is a new requirement for Win11 when it's released this fall. Minisforums engineering released a new BIOS/EUFI update that enables TPM. I am running the developers Win11 release and no compatibility problems have surfaced at all. So this HM50 is Win11 ready... ........................original post............................ Plenty of reviews out there on bloggers sites and on YouTube that provide technical details and stress testing the AMD Ryzen 5 4500U CPU and the AMD GPU. It scores very well in all the tests and is certainly no laggard by any means. It is still used in new name-brand laptops today so it's not outdated at all and runs like a scared cat. I've done my own non-scientific torture tests that go well beyond what I expected from this mini. I have three 24" 1080P monitors connected and brought up 3 different 1080P streaming videos - one on each monitor - all running at the same time. I had Netflix, Amazon Prime and YouTube video's all running and then looked at the Task Manger Performance tab and this mini was not even breaking a sweat. CPU at 17%, Memory at 4.8GB/15.4 (31%), GPU at only 7%. While all those were running, I brought up Lightroom 6 and started editing a photo as well Photoshop and the GPU usage went to 10%, CPU to 20% and Memory 5.5/15.4GB (36%). I then opened a word document in Libre Office, started a couple of app's (email and newsgroups ) and could not see any difference in the numbers. Still way below what one would consider high usage for any resource. I also tested both Ethernet ports (1GB and 2.5GB) as well as the wireless systems and they all work. I have 300MB/300MB service and the WiFi worked at spec. Not a single glitch... Certainly way more stuff going on than I would ever have normally running but... I'm also evaluating it as a replacement media / signage controller for a clients business with multiple monitors. This mini is now my daily driver and It has replaced a workstation I have that has dual graphics cards, 32GB of memory and 9 hard drives - all which made it an excellent room heater. With all the fans and hard drives spinning - it made some noise as you can imagine. I seriously doubt I will never need more power or capabilities than what this HM50 provides. I have 3 USB (4TB, 8TB and 10TB) drives connected to it and they remain fast even when copying files to all 3 at the same time. I installed two 500GB internal SATA SSD's (Samsung 860 EVO and a Corsair) for dual booting between versions of Win10 & Win11 and for running a Linux VM - just for playing around with. Not a single problem with any of the applications or any hardware compatibility issues - none. I have been in the computer / communications fields my entire career having used, programmed, built and maintained many different type systems from world-class size to now - Mini PC's. In my opinion, the most important part of any system is not the just the hardware or the software, it is the Customer Service and Technical Support that the company provides and how they stand behind their products. Yep, I tested both of those before purchasing the HM50 and I can say they are some of the best I have ever dealt with in all my years in this industry. I can't speak to reliability but they provide a 1 year warranty with a 6 month extension when you register. So 18 months warranty in total - I don't know of another manufacturer that provides that length of warranty unless you purchase it via a separate contract. Unlike some other mini manufactures I recently had to deal with for 5 months, I received prompt, courteous and accurate responses to my questions from Minisforum Customer Support (Nora) and Joey in Technical Support. Response time was a matter of a couple of hours and not days or a week or two later as with the other manufacturer. When I was looking for a replacement pc, a mini made a lot of sense for me. Big savings in power consumption. I cannot hear the fan even when the system is under a stress load and it does not take up a lot of space on my desk. It far exceeds my expectations. I have a home lab with about 10 other systems (full size PC's, laptop's and tablets) that I still use as test beds and just messing around with as part of my computer hobby. Now I do all my photo editing, writing and media watching on this HM50 and not lacking for anything. Remember that there are chip shortages now - and will be for a year or more which has driven costs up and that support is also part of the cost of any product. In time, Windows or some other applications or piece of equipment attached to it is going to create a problem and you may need some tech support in the future. I know that both the before and after -sale support was a positive 5 star experience for me and I expect it to be the same down the road. Lot's of choices out there to look at and I did a lot of research to make sure this would fit my needs now and still have plenty of power and resources for the future. It came with 16GB of Kingston memory and Kinston 512GB NVMe SSD for storage and can be upgraded if needed. It's plenty powerful and it just works....

Considering that this is a mini PC, I am more than pleasantly surprised by its performance. Most games run smoothly at medium resolution, which I would not have expected. It also has plenty of power for everyday tasks. Highly recommended.

UM890 Pro (32Gb & 1 TB SSD). After a few days it seems solid and robust. My biggest issue is using Win 11 rather than Win 10 (old PC). I seem to have everything set up properly and am happy with the outcome. I was concerned about review of instability, etc on Amazon. However when I looked more closely, near all negative reviews were for different machines with other CPU's, GPU's. So I went into this with some trepidations, since I only have moderate tech experience. So far, so good.

UPDATE 1/4/25 - The UM980 has an issue with Windows 24H2, I confirmed this with Minisforum. Their recommendation was to go back to 23H2, but though to do when MS doesn't offer it anymore. Minisforum knowing about the issue, removed the page for support of the UM980, including the links to drivers. I did get them to send me links to 3rd party pages that they claim have the drivers for this model. I assume once MS fixes the issues, Minisforum will again post their support page, but in the mean time I had to perform a clean install from Windows USB bootable device, and now this machine doesn't have updated drivers and seems to work Had this running for about a week now, it runs very cool compared with Ryzen 9 6900HX, and performs even better, and better frame rates! I would recommend this computer. I do wish MinisForum had better documentation and support, but I can figure things out when needed.
