Customers say

Customers find this mini PC to be a freakingly amazing piece of technology that’s extremely fast, running Ubuntu at mind-blowing speeds, and is quiet with barely audible fans. They appreciate its small size, with one customer noting it’s the size of an average internet router, and its gaming capabilities, with one mentioning it runs 1080p games well. The functionality receives mixed feedback – while some say it works great as a daughter’s PC, others report it wouldn’t power on. The ease of setup also gets mixed reviews, with some finding it easy to install while others struggle with the installation process.

    Powerhouse in a Small Package – Minisforum UM790 Exceeds Expectations!
    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!

    Great, virtually silent, fast, and really small, HOWEVER
    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.

    Nice minipc
    I ordered the UM780 XTX Mini PC AMD Ryzen 7 7840HS DDR5 32GB 1TB SSD. It came preinstalled with Windows 11 and I was surprised that it was somehow configured not to require a microsoft account to set up. I didn’t use Windows for very long, very quickly installed Linux. I tried Ubuntu, Fedora 39, and finally settled on Linux Mint 21.2 Victoria Edge edition because it has a later kernel and all the hardware is supported.The pc is fast, I mostly use it for software development and some light retro gaming. Everything works out of the box: wifi, sound, bluetooth, etc. The bios is not locked down and the interface is very intuitive. I contacted support about linux support before purchasing and they replied within 24h.The only thing I don’t like about it is the eye-blazing blue led built into the power button. When the machine is on, the blue light is on. No way to turn it off in bios. And it’s small, built into the power button, so would be difficult to tape up without interfering with the button itself. The computer came with a vesa mount so I’m probably just going to mount it behind my monitor so it’s less annoying.Right now it’s just sitting on my desk and under heavy loads I can hear the fan spin up. It’s no louder than a typical laptop fan, and much quieter that most gaming laptop fans. I probably won’t hear it at all once it’s mounted behind my monitor.Overall very satisfied with it!

    Great device, USB 4.0 issues make it useless for me
    I am going to start out by saying that MinisForum devices are little beasts. They work like a champ in normal conditions. But I have a use case that might not be so common. I bought the device to have my own little AI lab. But to save space, I got the UM790 pro and a Sonnet 750ex eGPU case, with a Nivida ti4060 in it. At the beginning this setup worked great. The Sonnet detected Thunderbolt speeds on both USB 4.0 ports on the UM790 pro and started up as soon as the cable was plugged. The Nvidia card was detected, drivers installed and a few AI models i loaded worked amazingly fast. But last night (2 days after initial setup, mind you i have owned the UM790 pro for 5 days as of this writing) the Sonnet is not powering on anymore. I tried connecting an external drive to the USB 4.0 ports to see if they are still alive. One is alive the other is dead. The live one is down to USB 2.0 speeds.This is exactly what happened to my UM690s as well. I was looking for solutions for that when I applied Bios V1.16 which bricked it. That one is back to MinisForum for repairs.I am not going to do anything with the Bios on the UM790 pro unless support says so. I have reached out to support and will keep this review updated. I hope a Bios update fixes this, I reallllly love this device and do not want to return it.Anyone planning on doing similar setup, beware.========= Update 07/19======Support reached out, offered to replace the device. I have not yet decided on that, since the 790 pro was purchased as a backup to my 690s which is back with support. If I send the 790 back, I will have no computer. Once the 690s comes back I’ll see if I want the hassle of disassembling the 790, and sending it back for replacement. And USB 4.0 issues could surface there, putting me back to square one. What no one is taking about is if a bios update will be provided to fix this issue. And looks like the store on Minisforum website and Amazon Minisforum store are completely separate. They don’t talk to each other or deal with each others issues. So the biggest deterrent to buying these devices is getting any support in timely fashion. If you just want to browse the internet or do some light photo editing where you won’t do anything stressful to the device its great. But if you do anything stressful causing any error condition, you cannot count on reliable and timely support.

    This computer runs really, really well even though it’s small and quiet. It has all of the ports I need, including enough USB’s and dual monitors. I really think this product has it all. Brilliant!

    Great performance compared to the last one I bought before this. Nice and powerful for a mini PC and reasonably affordable.I especially like that the USB ports are all high speed. Why even put USB2 ports on a modern device? It’s 2025! Just go with USB3! Good design choice!

    Hasta el momento todo bien con el producto, con 3 semanas de uso, le instale muy facilmente un SSD HP FX700 y una memoria de 32GB ddr5 4800mhz que ya tenía de un equipo anterior y va de maravilla, con 2 monitores conectados vía HDMI. lo uso principalmente para trabajar programando, en caso de viajar tener la flexibilidad de echarlo en la mochila y llevar todo ahí, tengo pensado comprar un par de monitores portátiles y conectarlo por USB4 tipo C ya que cuenta con 2 puertos frontales de este tipo. Muy rápido el procesador ryzen 9 7940HS sin ningún congelamiento o apagón hasta el día de hoy. Para el costo de 9 Mil pesos mexicanos se me hizo una buena opción, considerando que ya tenía la memoria y el SSD

    Great product – small form, quite, I leave it on pretty much 24/7 and when I’m asleep I don’t even hear it. Basic games like cs2 plays well on a medium setting. Very satisfied for what I needed.
