MINISFORUM UM870 Slim Mini PC Barebone AMD Ryzen 7 8745H Mini Computer(8C/16T, Up to 4.9GHz), Support DDR5 RAM,M.2 2280 SSD,8K@60Hz HDMI 2.1/USB4 Output, WIFI6E/BT5.3/Auto Power On(No DDR&SSD&OS)

I researched a fw products and used A.I. to help sort through what I needed: generally a browser-workhorse (00+ tabs open) and regular Office apps, no gaming. These mini-PCs kept popping up and seemed daunting compared to desktops and laptops, which I'm familiar with but what's the difference, really? I still just plug stuff in. I don't plan on upgrading or swamping this out for 5 years so I hoped this item will do the trick. There was one caveat that needed to be flagged – it would run loud dring high intensity usage, ie, gaming. I'm not gaming and have never once hit the whirring fan.Very compact and installed easily, took some time, of course, and able to use Wifi and install printers on Windows 11 Home.Very basic but it worked and able to plug in two monitors.Went with the larger rmemory setup so this should last for the time span and with 500Mbps internet speed, no lag whatsoever. This seems like the perfect model for the price point compared to laptops 9no need to move it around) and small desktops (saves much more space). It's been a month and no complaints.

This is my first gaming PC ever and it's also the main reason I got it. I've been a console gamer my whole life, but I've always wanted to get into PC gaming and could not due to financial issues. When I received a huge unexpected bonus from work, I started researching mini PCs and settled on this one.Since I'm new to gaming PCs, I'm not going to talk about overclocking, temperatures, or any of the technical stuff. However, I will say, that this PC is very quiet when playing graphics intensive games.I'm able to play most of the latest AAA titles like Cyberpunk at 1440p, 60FPS, and max settings (no ray tracing) using FSR. I've even been able to play some titles at 4K and 60FPS with max settings and FSR set to the highest performance setting.Besides gaming, this computer is super fast. I've never owned a PC this fast. I've only ever owned potatoes with integrated graphics that struggle to run indie games at 30FPS which I used only for work, so it's a huge jump coming from those types of PCs to a fast one like the HX77G. It boots in like 15 seconds. Applications open instantly. I got mine with 32GB of RAM and 500GB of disk space, but plan to upgrade to 64GB and 4TB soon.It's been 6 months and the PC has never frozen on me. I'm running Windows 11 with all the drivers up to date.This review is kind of late because I bought it last October 2023. Though I prefer to write reviews after owning things for a while and the honey moon period is over. IMHO, the honey moon period with this PC is STILL not over. It's really that good. I like it so much and I'd definitely buy it again or an upgraded model when I have the money.

Good computer. Well worth the money

Perfect PC for the price. I am very satisfied.

I have both 870 Slim and 890 Pro versions, they are both very fast and quiet with some minor issues.The main differences that makes the Pro version slightly better are (1) It is slightly faster, maybe 3% or so (2) has an NPU, but it is practically useless (3) Pro version has two ethernet ports instead of one (4) It has an oculink port, which uses the PCI port so, you can only install one NVme HD if you use the oculink port. These differences do not matter for most users.Overall I am very happy with both of them. They are both small, efficient, they don't get hot or make any fan noise. They can be directly powered from USB4 port, with some decrease in max clock speed.But there are some annoying issues, mostly minor things: (1) The wifi cards are not supported properly. The slim version had a wifi card which was not recognized by linux. The pro version had a slightly better wifi card, but was still an obscure brand. The issue is not the speed here, making them recognized by the OS. I replaced them both with more common models, it is about $20-30 to replace each. (2) The windows key was invalid in the Pro version. The Slim version was barebones it did not come with any OS. (3) The Slim version has screws at a very inconvenient location. You have to remove bottom pads glued to the box. Without the pads the vent will touch the surface and will not work well. It is not a good design. The Pro version is much better, but it has two cables attached to the lid on opposite sides, and it is not east to detach and attach them. If they were on the same side, the lid could be opened without detaching of them. (4) I tried installing 96GB RAM but it caused some glitch with the GPU driver. I tested the RAM and it was not faulty. 64GB or 32 GB RAM both work fine. (5) I don't like the bios, it is too rudimentary with very few options.Despite these issues, I like them a lot. This generation of AMD mobile chips (8945, 8745, etc) are really great. I also have a Mac mini pro (M2) and their performances are similar. Mac has a better GPU but the AMD is faster for most of other tasks.

My wife and I have had this computer for about 4 months. We have been genuinely impressed with the performance of this tiny PC for its size and cost. It boots up quickly, runs quietly, fits comfortably on the top of our computer desk, and given that we utilize cloud storage for most of our files, comes with more than enough built-in storage.It is also a more than capable gaming machine for older games (most of what we play). Below is a list of games we are ale to play at high settings without any issues:- Starcraft 2 (campaign and online co-op)- Dawn of War- Medieval 2 Total War- Age of Empires 3: Definitive Edition- Grim Dawn- Warcraft 3 ReforgedAugust 2026 UPDATE:- I recently did a clean install of Linux Mint. The process was seamless. The only downside is that the stock Mediatek WiFi/Bluetooth card does not play nicely with Linux.- However, I bought a $20 replacement Intel WiFi/Bluetooth card, and the installation could not have been easier. The card sits underneath the motherboard, so there was no need to remove it in order to change out the card. I only needed to unplug the fan.

It's amazing to have such a tiny CPU! It has been working very well for me.

Definitely only for light gaming even maxed out with ssd and ram. have already lost one network port for some reason but for light gaming, online shows, and general daily use, not a bad unit. USB Tbolt ports runs USB C video at 3840x2160 on HDR 10. Nice and crisp.

Excellent mini PC. No problem. Fair enough price. Very easy to add an SSD. Easy to mount on a monitor. Makes the table much cleaner than any other kind of PC, while without compromising on performance. The only thing is that the noise is louder than my MATX pc, but only when the CPU is working hard. I'm not saying it's noisy. It's still pretty quiet but louder than my MATX.

great product, good price and quick delivery

I'm happy with this machine. Very powerful, calm, doesn't get hot.

super fast, worker better than I expacted. no lag or speed issue. i use for some heavy use daily n0 issue at all works perfect

My son loves this mini PC . Very performant and fits the bill . We had an issue with an earlier order and they were very quick to respond and resolve it . Highly recommend!
