My wife’s laptop is old and SLOW. I decided to buy a better unit, not bigger, to handle some additional tasks and “gift” my other unit to her. The older unit is a GMKtec also and is still working well and still does all the basic things and is 10 times faster than her laptop which is all she needs. I am moving to do some video editing and picture manipulation and some CAD drawing, so I wanted something with a little more “kick”. This unit seemed to fit the bill and the price was reasonable considering the extra speed, storage and expansion capabilities, and after putting it through its paces – it fits better than expected! As always, my goal is to try everything I can as quickly as I can to try to see if I can find any issues that would cause me to return it or to have to contact the manufacturer. The harder I tried the more I liked the unit, I tried things like playing 4K Video (need to get more of that). 3D modeling and rotating the objects, standard CAD drawings, picture editing and storage, all without any issue and I noticed a distinct increase in the speed from my other units. This will be the third GMKtec unit I have purchased. Because of that I can heartily recommend their products and service. I had one issue with my first unit, and they took care of it quickly and answered all my questions. The unit came nicely packaged in a clean box. Everything came out easily and I have a picture of all of the components attached to this review. I followed the startup instructions and plugged everything in and turned it on, went through the startup process with windows and was on my way. One thing to consider with a minicomputer is that it doesn’t come with peripherals, specifically a monitor and keyboard and mouse. I already have a minicomputer, so I already have these. When my wife moves to the older box we will need to get replacements for her. I will buy a Bluetooth keyboard and mouse to minimize USB port use. This unit comes with 32 GB of RAM and a 1 TB SSD, and the unit is expandible to 4 TB. On my other units I quickly upgraded the RAM and Storage to what this one comes with so at this time I don’t see the need to add more which is a savings in time and money. I am now a fan of disconnected peripherals, keyboard, mouse, screen, portable drives, etc. it gives me the flexibility to disconnect and move them as I see fit or carry them with me while I travel. After I got the unit up and running, I started loading software and setting it up the way I like. There were no difficulties and it seemed to load and execute the installations faster than I am used to. I did do some speed tests and I know the modem has a lot to do with speed, but I was getting 96 mbps upload and download connected to the LAN with a cable and 94 mbps upload and download using the Wi-Fi connection. Plenty fast for my needs. I hooked up a pair of older speakers that use usb power and the earphone jack and they worked fine. Shows that it is downward compatible with older equipment. I left the computer on overnight to ensure there were no problems. It went to sleep and woke up without any issues. Earlier models had an issue with this, and I wanted to make sure it wasn’t there. I played avatar on the computer monitor and it worked great no lag no hesitations beautiful color. I figured 4K would test its graphics capability and my living room TV is 4K compatible. I hooked it up to the TV using the HDMI and found some 4K sample videos to play. They worked without a hitch, no hesitation, no buffering, and beautiful color, quite stunning I should add. I might start looking for more 4K stuff to play on the TV. I Downloaded Freecad which is a 3D modeling software, again flawless. I was able to reorient the 3D picture as fast as I could, and it looked like a movie. Along those lines I used a CAD drawing program also with no issues. Decided to do some graphic manipulation for a sales project I’m working on and edited pictures and moved them around again. It worked beautifully. Lastly as a graphics / speed trial I downloaded the starcraft game and played for a while. No issues. Other software I downloaded and used: Quicken, iTunes, Sonos (we have a system in the house), DropBox, Microsoft 365, Pumble So, this computer will take me to the next level I am looking for with speed, processing power, graphics and more. I had no trouble setting it up, using it and there were no manufacturing defects or problems. Since I have 3 GMKtec units now I can wholeheartedly recommend their products, and based on the interactions I have had they stand behind their products and provide support as needed to help. They are based out of China, so email has been my communication tool of choice even though there is a delay due to the time difference, but they have been very quick and responsive to my questions as their literature says “no question to big or small”

WOW! My new GMK Core i9-13900HK (NucBox_K10) has put a smile on my face. It's replacing an outdated Win 7 machine for our everyday use: research, email, entertainment, surfing, and some gaming. It came preloaded with Windows 11 Pro, which includes New Outlook. For sure, I was immediately very impressed with the K10's performance. Specifics: Device name NucBox_K10 Processor 13th Gen Intel(R) Core(TM) i9-13900HK 2.60 GHz Installed RAM 32.0 GB (31.8 GB usable) System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display Edition Windows 11 Pro Version 24H2 Installed on 5/1/2025 OS build 26100.4202 Experience Windows Feature Experience Pack 1000.26100.107.0 First, I updated the OS using Windows Update. The update took perhaps 2 hrs (typical given other users' comments re: Win11 updates). Next order of business was to install my security software and run a full scan: pleasantly, no issues. Bios access was simple using the esc key, though I had no reason to change anything. The machine runs extremely quiet and was very fast at all the tasks I performed. I'm currently using WiFi and the GMK K10 is equally distant from my router and an Access Point in the lower level. I tested performance on 4 local networks I had defined: Router(2.4 and 5.0) and AP(2.4 and 5.0). No matter the network, the GMK K10 was impressively snappy. The wi-fi antennas are clearly a plus. Web pages appear in a flash, and every task I perform delivers at turbo-speed. I ran multiple applications simultaneously with numerous tabs open and everything ran flawlessly. I plan to add a second SSD and the easy access panel on the underside should make things easier. Additionally, the Kensington Lock capability provides for a layer of physical security if that's an issue. On the flip side, the power button could use better illumination. Depending on ambient lighting, it can be difficult to tell if the machine is on or off (a tribute to how quiet it is). When I ran the OS update the screen went blank multiple times and, judging from the power button, I didn't know if the K10 was asleep, in the middle of a reboot, shutdown, or even if the update was complete. In sum, the GMK K10 is a great machine. Big shout out to GMKTec, I'm impressed. If you're looking for a low cost, up-to-date upgrade to replace your present pc, you should consider the new GMK NucBox_K10.

At first I was a bit worried about buying an “off brand” machine, but now I must say this is one of the best computers I’ve ever bought! This little thing is a BEAST! I use it for development and running AI agents and it literally never slows down. The computer stays on 24/7 and is blazing fast. Price is extremely good. The machine runs super quiet and I’ve had zero issues with overheating. Price is perfect, can’t say enough good things about my GMKtec.

(A little bulky but still OK...like a typical laptop power supply) Power supply seems to have adequate head room to power all my peripherals (i.e. mouse / keyboard / External Drives etc.) HDMI cable and mounting bracket included. Upgrading is easy...The top cover pries off. Then 4 screws on each corner allows removal of the chassis fan. (Be careful to note the fan has a power cable that can be inadvertently yanked.) This exposes the NVME and RAM slots. SEE Photo #1 / Photo #2 / Photo #3 BOOT TIME AFTER ALL INSTALLS: Initially, boot time from pressing power button to fully loading all processes was 19 seconds. 14 sec to desktop fully revealed. This settled into a consistent 17 seconds and 12 seconds to fully revealed desktop. See Video #1 and Photo #4 / Photo #5 BIOS: An interesting BIOS feature that I could not figure out to configure was RAM disk. The high performance of this computer and the large amount and speed of RAM would make a RAM disk likely not worth the effort for most people. Researching RAM disk issues on line shows a significant number of computer enthusiasts with this sentiment. The Power Mode parameter in BIOS on the Advanced tab has 3 settings: Quiet / Balance / Performance I chose performance. Other BIOS categories are shown in photos. See Photo #6 / Photo #7 CPU THERMAL: My CPU temperatures rarely got above 60C to 65C and on a very few occasions into the 70's. Typical idle temperatures are between 35C and 40C. Fan cooling seems to be dynamic so that fan speed ramp up as temperature rises. My chassis fan never ramped up enough for me to even hear it. I had to open the case to confirm it was spinning at a low RPM. See Photo #8 NVME DISK BENCHMARK Lexmark 1TB PCIe 4.0 : I did two benchmark tests with ATTO and CRYSTAL DISK utilities. ATTO scores were slightly lower overall but it is safe to say this drive reads at 4.8 - 5 GB/s and reads at 4.3 to 4.5 GB/sec. This is a reasonable exploit of PCIe 4.0 potential. See Photo #9 / Photo #10 PRACTICAL TESTS: To give you an idea of just how fast this computer can be: I have a 2TB NVMe drive in an enclosure as an external drive for computer backups. I use Macrium Reflect backup software. On the USB 4.0 Type C port, my Macrium Reflect backup of this computer took 1 minute and 3 sec to create a 53GB backup image. Keep in mind though that the data transfer here is from an NVMe drive to another NVMe drive on a USB 4 port. I also tried opening 15 Excel spreadsheets at once and they all loaded in less than 10 seconds. GRAPHICS: I do no gamimg so I cant say too much but the Display Port supports 4K @ 144Hz so some gaming is definitely possible. There are certainly sufficient computing resources here for gaming though. I streamed 1080p for long periods with absolutely no problems. CONCLUSION: When travelling (which I do frequently) I used to bring a copy of all desktop files with me on an external drive and then work from a laptop where I would migrate email and internet browser profiles to the laptop and then resync everything from laptop back to desktop when I got home but I can now just bring this computer with me and a small monitor. Furthermore, I used to have a desktop in my office and one in the bedroom. Now I just carry the K9 from room to room as needed since I have keyboards and monitors in both places. With the fast NVMe drive and the huge amount of fast RAM I can't find any downside to this machine. Its performance rivals any desktop that I've ever used and it's portability means that I can pack it up and bring it with me anywhere. There are enough USB Ports to cover peripherals like printers, portable optical drives, hard drive docks etc. It is a completely adequate full desktop replacement..... a mini power house. Whether it is audio or video editing, music composition and multitracking, VST instruments, a gazillion internet tabs opened at once, there are adequate resources to do anything I can think of. I can't think of a downside to this computer with regard to performance. You may need USB extenders to provide clearance when using many peripherals because it can get a little crowded with some ports configured close together but it isn't any worse than what you would find in a laptop. This machine shows an impressive performance for a computer of any size. I am very happy with it and do not regret this purchase.

I was looking for something to replace my N100 mini PC, that replaced my old tiered i5 desktop that runs my PMS. The mini N100 PC was doing a pretty decent job until I decided to run Emby and Plex on the same PC, both would buffer frequently if both were running and transcoding at the same time. It was a bit much for the N100 and Intel UHD intergraded graphics to handle. I didn't want to go back to a full sized desktop, and stay in the mini platform if I could. I came across this mini PC with the i9, which has the Intel iris XE intergraded graphics that I gather is a monster step up from the UHD intergraded graphics. Everything I found while researching stated the the iris XE was capable of chewing through multiple streams of transcoding simultaneously, even up to 4K. I figured I'd give it a try and it's been running for about a week now and it has handled three 4K transcoding streams at the same time without any noted issues so far. It does get pretty warm, so I added a cooling plate under it and vented the cabinet it sets in with an intake and exhaust fan to help keep it cool and prevent any issues with overheating. So far I am pretty impressed with this mini PC, for its size it's pretty fast and seems pretty powerful for such a small package. The 32GB of DDR5 is nice, but at some point I will step that up to 64GB+ so I can dedicate a bit more RAMDisk space for transcoding, but for now it is doing great. I don't notice any more noise from it than the N100 mini PC I have, but it is in a cabinet so I probably wouldn't hear it that much even if it was a bit louder. I can't speak to the longevity of it, as I've only had it up and running for about a week now but so far I have no complaints or issues to report. If anything changes I'll will update my review of this product. It made a noticeable difference going from the N100 processor with 16GB of RAM to the i9 with 32GB of RAM, and so far I am pleased with its performance for what I am using for.

I have been using the K9 for about a week now and it works great for my purposes. I needed a better computer to use with my pen display to do graphic design and create digital art. I also have limited space, so wanted something small. This fits the bill. First of all, this thing is fast. It loads up in about 20 seconds and I am able to work on Clip Studio files with dozens of layers with no slow down or lag at all, even if I have other programs running at the same time. There is some fan noise, but it is low enough that for the most part I don’t notice it. There is also a quiet mode but I have not felt the need to use it. One thing that I was not expecting is that I can power the mini through my USB-C monitor. My monitor only outputs 90W, which is less than the power supply that came with the mini, but the mini works great just being plugged into the monitor without needing to be plugged into the wall. I won’t be using this feature because I was unable to daisy chain my pen display from the monitor when attaching the mini through the USB4 port (I had to use the DisplayPort to get this to work), but this is a really nice feature for someone who wants fewer cords and doesn’t need to daisy chain monitors. I attached photos showing both setups. I also really like the look of this mini. Very simple and clean with a silver finish, which fits in perfectly with the rest of my setup. It looks metal but feels plastic and I assume it is. My (non-expert) understanding is that metal is better for heat dissipation but plastic is better for Bluetooth and wireless reception. I use wireless internet, so my preference is for plastic, assuming there are no heat issues. I did not run any tests, but I have not run into any overheating issues with this computer. As far as gaming is concerned, I was able to play at 2k 120fps (the maximum settings for my monitor) no problems. I’m not a huge gamer and don’t have any AAA games, so can’t comment on that, but I do like playing games with my kids and the k9 worked great for everything I threw at it. Overall, this has been a great computer for me so far. It’s small, fast, looks good, and not too loud.

When I first bought it, it worked normally for a few months. Then it started rebooting for many different errors. I wasted a lot of my time with troubleshooting and fixes. I reset the BIOS to it's default setting and even reloaded Windows 11 in hopes that it would fix it. It still has multiple errors and now it only reboots itself 1-2 times an hour. I can see other folks have accomplished reviews with the same issues as I have with my computer. What a pain. I will not buy from this company again. I do not recommend this product.

Device works exceptionally well, support is non-existent. I wanted to replace the 1TB NVMe drive with a 4TB, and ran into issues because their website instructions and files didn’t work. Tried their website support, tried their support number, no joy. Gave up, cloned their drive and used the remaining 4TB as a second drive on the same NVMe. A+ for the i9 and its performance. F for their support. What worries me is if I have a problem in the future… where do I get parts or support? Is this a disposable lighter PC?

Fast, cool and quiet. Im not a gamer and I also didn’t use the pre installed windows. I use NixOS and it’s was a breeze to get it going. Compile times are day and night difference as compared to my older 8th gen i7. The disk drive is fast enough but can be improved with a later purchase.

منذ الشراء حتى هذه اللحظة كل شيء يعمل بكفاءة وأداء عالي اكثر من ما توقعت، استخدامي للكومبيوتر في الأعمال اليومية والمكتبية بالإضافة الى القليل من برامج التصميم، الأداء كان وما زال اكثر من ما توقعت قبل الشراء، أداءه اكبر من حجمه الصغير ويمكن تثبيته بشكل مخفي، أنا قمت بتثبيته تحت سطح الطاولة، انصح به و ربما قريباً أقوم بشراء جهاز آخر،

It is very good and fully satisfied. Many thanks to Amazon in general and to the main manufacturer GMTec in particular and great thanks to Ms Lara for her prompt response and detailed feedback back on the product specifications

This little machine is perfect for a home office. It was effortless to setup, and very easy to connect to a tv through HDMI or a screen with display port. It runs all applications, even light games. It does struggle with heavier games. I had to contact tech support for an issue downloading the image for the machine from their site, they where both extremely responsive and helpful - I now have both the Image and drivers for my M3 Plus.

I use this for 3D modelling and printing, as well has drawing. Zero difficulty setting up and fast!! Haven't tried any gaming on it yet but the video quality is outstanding. My only thing. Needs more USB ports
