I’ve been using the Minisforum UM790 Mini PC for a few weeks now, and I can confidently say it’s been an outstanding experience. This little machine packs a serious punch! I’m able to play all the games I want with smooth performance and solid frame rates—even more demanding titles run great with the right settings.Beyond gaming, it’s been a beast for video editing. My editing software runs flawlessly, and rendering times are surprisingly fast for such a compact system. It’s rare to find this kind of performance in a mini PC, and the UM790 absolutely delivers.Build quality is solid, it stays cool and quiet, and the design fits perfectly on my desk without taking up space. It’s truly a great all-around mini PC for anyone who wants power and versatility without the bulk.Best part? I’m writing this review using it right now—and it hasn’t missed a beat.Highly recommended for gamers, creatives, or anyone needing a reliable, high-performance compact PC!

I have had this mini computer, with its "on motherboard", AMD Radeon 780 M Graphics card for almost one full month. When it worked correctly, it was fabulous, other times, it would load but refuse to show (on screen) spreadsheets or PDF editing programs. If I restarted the computer, it would work correctly for a short time, and then the same problem would crop up. Really, really, frustrating. Eventually, I stumbled on the "AMD, Adrenalin edition" video card enhancement package. Download and install the package; it searches your computer to determine what you have, then it installs the correct, updated drivers. This package is intended to maximize your gamming experience. I don't game. BUT, it seems to have fixed my problem. My Bluetooth mouse now works just fine and all the video, PDF and spreadsheet programs load and work.The actual computer is about as long in width, length and height as a standard desktop stapler. It is nearly silent, except for the few moments the CPU is working hard. It can handle multiple monitors, just like description states. Did I mention it is pretty fast, comes with Windows 11 pro, is really small, and virtually silent.This is a great computer, AFTER you install the "AMD, Adrenalin edition" video card enhancement package.

I bought a UM790 Pro a month ago. I had to replace a very old PC. My main use is photo editing, and the old one couldn't keep up with current software. This is lightning fast compared to what I'm coming from. Handles everything I throw at it like a champ. I even added an extra NVMe hard drive with no problems. But like many people have mentioned, the WiFi signal was pretty weak. And unfortunately, I can't move it closer to my router. I ordered an external USB WiFi adapter to compensate. Unfortunately, the PC inexplicably died within a week. Wouldn't even power on. So I returned it for a full refund.Hoping it was just bad luck, I ordered another. It seems Minisforum was paying attention to reviews and made an unannounced update to fix the WiFi. When I opened it up to put in my extra drive, I noticed that the WiFi antennas are no longer attached to the bottom plate, but fed somewhere higher in the PC (I didn't go digging around to find out where exactly.) So far, WiFi is working perfectly. My signal strength is markedly improved over the last one. Before, I couldn't even get the 5Ghz signal, and the 2.4Ghz band was pretty weak. Now, both bands are incredibly strong. I am super impressed. I don't need the external USB WiFi adapter for this one. Kudos to Minisforum for the update. Plus, it came installed with BIOS 1.07, and I updated the BIOS to 1.09 with no problems. It now lets you allocate 16Gb for VRAM.I am extremely pleased with the UM790 Pro. It's running strong. Doesn't even break a sweat with my biggest Photoshop/Lightroom files. I'll update if anything changes.

I built a AMD 7950X desktop with water cooled CPU. It ran very hot all the time, even when set the CPU to 65W and only running one VM. So I decided to try the UM790 PRO 64MB/1TB to reduce the heat in my office. I run linux on these boxes. I added a Samsung 990 Pro 4TB NVMe, and just recently removed the supplied 1TB NVMe as it was running hotter than I wanted (since I was not really using it).This has a 7950HS (laptop) CPU chip, so instead of 64 threads like the 7950X, it has 32. It has no HDD, so no mechanical parts, except for the 2 fans. I run 3 monitors, docking station, with 2-3 trading programs (updating all stock quotes every 3 seconds), many tabs in firefox and chrome, and monitor several servers. I back up nightly critical file server and VM files. This machine handles it all with no problem and maintains a cool and (was) quiet environment. I don't realize the 32 vs 64 threads difference. I probably run 5-10% CPU most of the time, that is how fast this CPU is. CPU runs maybe 45C/114F. Samsung 990 Pro runs 37C/98F.Recently, like I think many people after 6 months to 1 year, one of the fans has started to have issues after less than a year. It was dead quiet in the past, but now has a wobble and makes enough noise to be noticeable in a quiet room. Getting a replacement fan is a problem, the fan manufacturer doesn't sell it anymore but maybe available in China, and will likely require soldering wires to use the special connector is a second bigger problem. Even minisforum has changed the fan they use for new models. I get a mini computer or laptop needing custom fans to cram into a tight space, but wish replacements were easily available. In short, going to be a difficult time replacing the fan.Except for the new fan issue, I love this mini computer. It has changed my mind about mini computers vs desktop computers. Desktops are still good for file servers and burning BDs. This computer is fast, capable, expansive, lots of features: all around a great machine.This computer deserves more than 5 stars with a good fan and maybe 3 stars with the fan issue.
