Wow, very fast for just 15 watts of power.
Size: R3 5400U 16GB DDR4 + 512GB
Edit update again 01/10/2025: I fixed my fan issue and as promised raised the score back up to 5 stars. It is a good, fast little computer but does get hot when you are gaming. I recommend popping the top off and exposing the top fan to the outside as this really helps in keeping it cool. When you put the top back on, when your finished, don't snap the top back in place so it will be easy for you to remove when needed. I know this would bother some people but I am not bothered by it as it helps keep it cool. Still five stars for what it can do for it's size. Still highly recommended. Edit up date 01/09/2025: I had to reduce the GMKtec M5 Plus from five stars to three stars because the little top cooling fan will not work all the time. I have the lid on but not snapped in because I have to take it off to force the fan to run. A quick spin with my fingers gets it going but I got to keep an eye on it other wise the little computer will over heat even though it's only fifteen watts. This is serious and the reason for only three stars. I am going to try to contact them and if they help I will improve the review back to five stars. *Next is another concern that has a lot of YouTube press and that is, Mini PC's shipping out with Malware or viruses. Let me make clear that GMKtec has been cleared so far and I tested mine forward and backwards with zero positives but you should be made aware of this. The most offending company (watch YouYube to get the companies name as it is all over) still has not completely cleaned their computers and are being very sneaky in the way they hide the Malware. One buyer replaced his M2 SSD and loaded a fresh copy of Windows 11. If you are one of those people who are sensitive to computer security then you need to know what you are getting into with Mini PC's. I didn't know this before I bought mine. Please check out the problem on YouTube before you buy. If you do buy, do not connect to the net till you have run a complete check. I recommend the very long but important Windows 11, full virus scan and download the free version of Malwear Bytes and run a test with that. I hope Amazon allows this review update to be printed as this is an important issue that everyone should be made aware of before they buy a mini PC. First off, it worked right out the box. Early setup could not have been any easier, a smart 8 year old could have set this mini computer up. That's not stretching it either. However setting up all the drivers from AMD and getting Windows 11 up to date did take time and requires someone a little more knowledgeable. I bought this as a novelty but now using it all the time. My big gaming computer has taken a back seat to this amazing little mini computer. Pros: Very quite, Very fast, Yes it plays games but more on the casual level. Beautiful eye popping monitor visuals, It uses only 15 watts of power. That means it runs very cool. The AMD processor the 5825U is designed to run on 15 watts. Cons: Terrible instructions with tiny print. Example, they send you a piece of black metal with some black screws that looks like it might be some sort of mounting bracket but the instructions give you zero information on what it is for. It uses only 15 watts of power. I know I had that as a pro but it could also be a con if you want to play more powerful AAA games. But who would use a mini computer to play AAA games like Cyber Punk 2077 or Hogwarts. Come on, use common sense. I will end this by saying do your research. Not all mini computers are only fifteen watts like this one. And if you look you will find the newest mini computers are AM5 platform and use up to 70 watts. But those units run from seven hundred and fiftly to almost a thousand dollars. You start spending that much money you might as well buy a full size gaming rig. Highly recommended ... show more

In my real life, I am a Technical Writer and Knowledge Manager for the company I work for, so if this review seems a little long or maybe too detailed, I wanted to make sure you got as much information as possible as I started using the computer. At home I am an avid movie and personal video collector and I just completed rebuilding my video server. It is in a tower case and is occupying the only space I have in my office for such a computer. As part of the rebuild, I intended to separate the serving and processing functions, so I was searching for a compact solution that would allow me to render video content for the server. This computer has provided everything I was looking for and more. These are the criteria I used in deciding on a replacement computer High speed processing I needed a computer that would help with video rendering. I am not a gamer but the performance of a gaming computer would speed up the video work I do. With the initial testing, this design is completing the rendering tasks about 20% faster that my previous computer. A compact Design. I have limited space on my desk for a PC. This mini PC was great as the size gave me options on my already crowded desk. Its size allowed me to place it behind a monitor, but there were also 2 mounting screw holes in the case so I decided to mount it to the back of my desk. Convenience of Several connection options. With 4 USB A ports I was able to connect my printers, keyboard and mouse and still had USB C connection options for my USB monitor and an External SSD device. See the picture Exterior Pictures Showing Ports and Top Removal Along with that connectivity there are options to connect wireless networks and to use Bluetooth top connect audio devices like headphones. Expandability In this small package I could still add an additional standard sized SSD. The surprise expandability is found in the Oculink Port this port gives PCIe connectivity speed for external devices. What Came in the Box The computer Introductory Booklet (Unfortunately not an English Page, but other picture have some English labels.) Power Supply and Power Cord HDMI cable (Must boot first time on HDMI) Mounting Bracket (No instructions on the exact uses. I mounted mine using the mounting holes on the back of the case.) See the Picture What's In the Box Setting up the Computer Unpacking the computer was straight forward. There was no assembly required. The only things needed to get started is a monitor to connect the HDMI cable (provided), a keyboard & mouse and to plug in the power supply. I followed the instructions on the yellow notice over the network ports advising that the system would set up much more quickly without Windows attempting to update during the initial boot up. This worked great and I will use this process on any other computer I will build. Within a few minutes, I was at the windows desktop. I was in a position to start installing software. See picture Original Desktop. I then connected a network wire and I was able to install my software and connect to my Microsoft account. There was a bit of disappointment, as there were no instructions in English supplied. There were about 10-12 languages in a pamphlet included in the box but none were English. The drawings were labeled well enough to identify the details of the ports well enough for my trained eye, but the standard user may be left with questions about a few of the ports. I decided to add a second SSD to the computer and found the access inside very simple. Turned the top shield a quarter turn to the left and it unlocked exposing 4 screws that held the top fan in place. Once those were removed, the fan lifted out easily (be careful of the wire connecting the system board to the fan.) See the picture Disassembly with SSD 2 Slot Identified As part of the final setup, I had to decide where the computer would be on my desk. I had a option to put it behind my monitor See Picture Behind the Monitor, but instead, I took advantage of the mounting holes on the bottom of the computer to hang the computer from the back of my desk. See the picture Desk Mount BIOS Notes I did look at the BIOS. I was curious about how configurable it was as I have found with other units that the BIOS is very focused and not designed to allow tweaking. While the interface was not very fancy (very DOS like) it appeared to have several settings to adjust memory and processor. See the picture BIOS Advanced There are many drill down options. Summary Overall this computer provides a significant performance boost over the equipment I had. In my research I found that the AMD products provide better performance for the dollar, combined with integrating the GPU into the chip design it made the unit compact while still providing enough horsepower to drive 3 monitors effectively. In the few days I have worked with this unit, I still find myself marveling at how fast bootup times are and how quickly applications launch and web pages load. If you are looking for a gaming computer I would give this one a chance, I think you will be surprised at the speed of this computer and its ability to keep up with some of the most demanding games. ... show more

Impressive engineering at a very reasonable price.
Size: R3 5400U 16GB DDR4 + 512GB
The short form: I wanted a small form-factor computer for general work and light-duty gaming. This machine provides it admirably. The longer form: I chose it because it promised a decent level of gaming performance for the one game I play, World of tanks, at a decent frame-rate without its having a to have a noisy, secondary fan to handle the kinds of heating that the additional performance needs. What I have, and what I'm writing this review on, is a machine that handles world of tanks with low medium graphics settings at a frame rate of 40-60 fps with a highish ping which fulfills my basic needs, and it can do more if I turn it's graphics settings to low, at which point its frame rate goes to over a hundred-and-ten fps which works to make up for my senior-citizen reaction speeds. For the general work requirement, it is more than adequate, as in "much more." I can run multiple applications on multiple desktops and stream video (Amazon, Netflix, etc.) with no problems. Although I am transitioning from Mac to Windows in order to use it, I found its set up was a fairly simple process. One very pleasant surprise of the thing is just how quiet it is and competent the thing has been. Right now, I'm running several different, none-too demanding apps, and the fan is barely audible. And, even when I run my gaming app, the top of the box has never gotten more than perceptibly, but not uncomfortably, warm to the touch. The artificial intelligence app built into the operating system is a surprisingly good knowledge-base that greatly extends the power of search engines to answer general knowledge and technical questions. It was particularly useful when the computer started crashing when I played YouTube videos. The suggestions it provided got me back normal function in minutes. Considering how internet integrated modern operating systems are, I think it is imperative that you buy and install antivirus software as your second act with this or any computer. The bottom line I am perfectly happy with this computer. I would like a smidgeon of additional graphics power for gaming, but, considering my needs and the price, and after a month of use, I am very satisfied with my purchas, and I would definitely recommend it to someone like a college student or a light-duty gamer who was willing to trade a small amount of graphics power for noise-heat-and-hassle-free operation. ... show more

1 weird glitch, but otherwise, AWESOME
Size: R7 8845HS 32GB DDR5 + 1TB
My unit has a weird bug where if it goes to sleep, it will hard reset when it wakes up. (Kernel 41 error). Not a HUGE deal, as I just turned the sleep function off, but certainly makes me wary of other potential hardware fails or glitches. GMKtec did get right back to me about the issue through customer service - they suggested I edit something in the system registry - but I didn't want to mess with that. All in all though, I'm very happy with this. Machine is quiet and fast. The last PC I bought was in 2013, so you can imagine how far the tech has come since then. This thing is just blazingly fast with 32GB of RAM. I have no complaints about the quality of the build - it's sturdy and easy to use. I don't use the WiFi, I use an ethernet cable, so I can't comment on the WiFi issues some people experience. I would buy it again, to be totally honest. I'm excited for the future of mini PCs. I use it for some light gaming - CS2, guild wars - but it handles CS2 like a champ so I'm sure it can handle most games on low to mid settings. Older games run on high, obviously, no problem. EDIT: 6 Months /////////////// I have had instances where I need to use the WiFi and it has worked fine for me in those scenarios. Nice! Would still recommend it to someone who is maybe on the savvier side of PCs. I definitely still don't trust it 100% to not fail on me, and I back everything up on an external. ... show more

Great Linux Developer Machine
Size: R7 7730U 16GB DDR4 + 256GB
I wanted an affordable Linux developer machine for my WebDev business. Didn't really need a full desktop machine with powerful graphics. Just needed a solid processor, a good amount of RAM and storage. This GMKtec checked all the boxes. Given the price I wasn't expecting an amazing industrial design like a Mac Mini. It's pretty plasticy but has all the ports I needed. It's powerful enough to drive a couple of monitors. Boots up quickly and performs well for the spec. I was able to quickly partition the drive, load my favorite Linux distro, and get to work fast. No driver issues. A solid buy. Calling it a Gaming machine is a stretch. It might be okay for simple games but nothing to graphically demanding. ... show more

Serious power in a travel-sized PC!!! I can't say enough good things about this machine, and no, I'm not an employee or anything like that, but this is my second GMKtec mini PC. My first one has been great, but I wanted an upgrade that could handle more demanding games and run a local AI model at home. The K8 Plus was exactly what I was looking for. The Ryzen 7 8845HS has plenty of power, and getting 32 GB of DDR5 RAM at the current price makes this an especially good deal. Everything feels fast and responsive, even when I’m gaming, running AI workloads, or heavily multitasking, which I'm doing frequently. One of the biggest selling points for me is the OCuLink connection. I can connect an external dock and graphics card for demanding games or use a dedicated GPU for AI. That gives me the portability of a mini PC while traveling and much more processing power when I’m home. I also really like the case design. The outer top section twists off easily and can be removed for additional airflow during extended gaming or AI sessions. Beneath that is a separate panel secured with just 4 screws, that provides easy access to the RAM and SSD slots for upgrades. I moved my hard drive from the previous machine over, and had no issues. Overall, the K8 Plus packs a surprising amount of power and upgradeability into a computer small enough to travel with easily. Between its performance, 32 GB of RAM, OCuLink support, USB4, and compact size, it offers a ridiculous amount for the money, and I would definitely recommend one of these! ... show more

Excellent pc for an excellent price! (i got it on sale though :P) It's small, silent, has every peripheral you could need on a mini pc, though i'm using mine for pfsense. I had trouble setting it up though because of the realtek NICs. Julian was an absolutely amazing and thorough help though when i emailed their support team. I wasn't the most polite and yet they messaged me back within a day with a detailed and thorough explanation on how to fix the problem. This is everything you could ever want out of a product, a good product, for a good price, with amazing customer service that DOES go the extra mile when it comes to support. My little GMKtec square now sits comfortably mounted upside down (did i mention the mounting bracket is great too?) in my home made tv stand looking perfect. ... show more

An unexpected jewel, however...
Size: R7 8845HS 32GB DDR5 + 512GB
I am not a gamer, but I decided to buy this PC for one of my workstations primarily for business as I had slowness issues with other devices. I wanted horsepower, but a small form factor which I didn't think would exist until I discovered this machine. I have been blown away by the speed and responsiveness of this device. It is lightning fast and responsive to running many memory intensive business applications. I also have 3 monitors connected to the device since there are 2 HDMI ports and one USB- C port that can be used to support a 3rd monitor. It is definitely worth the price and adding the coupon code makes it even more of a value. There is no bloatware like other PCs out of the box have. If you want a high performing PC at a 1/3 of the cost of other well known devices to handle business applications, then look no further. This hidden gem is definitely worth it! Update 2 months later: This little device is still going strong without issues. I have been pleasantly surprised with its speed and the ability to handle multiple applications at once without performance degradation. This is such a great machine that I give my highest recommendation. Update 5.5 months from original purchase: Over the course of the past few weeks, I have experienced some major issues with this device. 1. Network Intranet Speed: I just added fiber internet to my home at a very fast speed tier. All other hardwired devices are reporting appropriate speeds, but this device is showing a download speed significantly lower. I have changed the cables multiple times, but still get lower speed. The only way to resolve this has been to completely disconnect the cable and reconnect it. But after a few hours, the issue returns. Because I rely heavily on video conferencing for work, I have have found this aspect to be unreliable. 2. AMD Processor Errors: As mentioned above, I do a lot of video conferencing for work. About 2 weeks ago, I began receiving fatal errors about the processor as I use Zoom or Google Meet for these calls. The computer froze and I had to restart the Zoom session. This was not a good experience as I missed critical information communicated on the call. I'm likely going to put my old computer back in place since it was far more reliable than this. ... show more
