  • Great little PC – Well worth the money Great little PC – Well worth the money
Like many of us the time arrived to upgrade from Windows 10 but my outdated PC couldn’t be upgraded. I prefer desktops but the new Windows 11 models were outrageously expensive. So I did some lookin’ around and discovered the world of mini PCs. Based on other reviews I zoomed in on GMKtec, and this model Nuk Box M6 Ultra seemed to have all the capabilities I needed: Compact size, fast processor, SSD drives and DR5 memory. And with this model you can even upgrade the SSD and the memory. It also comes with built in WiFi and Bluetooth. I received the PC in a couple days, plugged it in and in minutes it was up and running Windows 11, though it did take a little time to connect to Microsoft and upgrade the software. The nice thing is that it only takes 22 seconds for the Windows desktop to appear after I turn it on! It is very fast and from the video I uploaded here you can see it not only supports 3 monitors but plays three video streams at the same time flawlessly without a glitch, stutter or freeze. I also had no problem with WiFi connectivity as the PC detected and connected to my WiFi quickly and seamlessly. There was also no evidence of overheating, and fan noise was hardly noticeable (my cat purrs louder). The sound though headphones and external amplified speakers was crisp without static or fuzziness. I can’t comment on the types of games you can actually play on the M6 as I’m not a game player but from other reviewers it seems they were quite satisfied with its performance. I was totally satisfied the number of browser windows I could open and programs I could run simultaneously. . The only thing I question are the inclusion of two LAN jacks as I don’t believe two are necessary or practical for home use. There is also no separate microphone input jack however that is easily overcome by using an inexpensive audio splitter cable or a USB microphone. Finally a live chat box would be nice for solving problems without having to play email tag. All in all,the M6 utlra performs like a little workhorse, and for the money, it’s a great value. ... show more

  • The Oculink and Dual USB4 features make this a desktop killer!
I was incredibly skeptical when I first saw the specs for this GMKtec Mini PC. Usually, "Mini PCs" are cramped with slow SATA SSDs and limited connectivity. This unit is total overkill in the best way possible! The Performance is Insane: Starting with the AMD Ryzen 7 PRO 6850U processor paired with a massive 32GB of DDR5 RAM and a speedy 1TB PCIe SSD, this machine feels like it costs triple what I paid. Multitasking is effortless—I have dozens of browser tabs open, Docker containers running for my NAS, and video editing software all without any lag. The "PRO" chipset is quiet, efficient, and runs cool even under load. The Connectivity (The Real Hero): This is where this unit blows the competition away. Most mini PCs rely on dongles, but this has everything you need right out of the box: Oculink Port: This is a game-changer Literally 🤣. It allows you to plug in an external GPU (eGPU) seamlessly, giving you desktop-class graphics power without the bulky Thunderbolt 4 eGPU enclosures that take up too much desk space. Dual USB4 Ports: Having two of these high-speed ports is rare on a small PC. I use one for my primary docking station and the other for direct connection to an external monitor (via DP Alt Mode) or a storage dock. I226V Dual NIC LAN: If you are into networking, this is heaven. Being able to have two 2.5G Ethernet ports built-in means I can dedicate one port to my internet router and the other to a server connection without using USB Wi-Fi adapters that always disconnect. Build Quality: The chassis looks premium (the matte finish in the photos is accurate), and the heat dissipation seems very effective given how much power this chip is packing into such a tiny footprint. It doesn't take up any real desk space, but it handles workloads that usually require a full-sized ATX tower. If you want a Mini PC that can actually do serious gaming (with an eGPU), act as a home server, or serve as a high-end workstation, this is the one to buy. Highly recommended! ... show more

  • This MINI PC... Games (and a whole lot more)! This MINI PC... Games (and a whole lot more)!
This is my 3rd Mini PC from GMKTec, and I've been very impressed with all of them. This latest model has an AMD Ryzen 9 8945HS with integrated Radeon 780M graphics and is being marketed as a mini gaming PC, so I thought I'd put it to the test. I installed Fortnite through the Epic Games Launcher and asked my son to demo. I attached some pictures and a video, but he was surprised at how well it ran the game on high settings. My monitor tops out at 2K resolution (2560x1440 pixels / QHD 1440p), and while not 4K, he was still playing with good quality and frame rate without having to drop to 1080p (which is fine too). The fan does get a little noisy during heavy loading (i.e., gaming), but it isn't too bad. I recalled my first GMKTec mini PC has the ability to run in a lower power mode with slower fan speeds through BIOS adjustments, so I looked through the BIOS on this PC but didn't find what I was looking for. I'll need to dig a little deeper here. This PC has Windows 11 Pro 64-bit, so Pro is an unexpected upgrade, although with the networking capabilities this PC has, it probably is a necessity. It has 32.0GB RAM and a 2.0TB SSD. There are traditional USB A slots on the back for keyboard and mouse, but it also has numerous USB C 4.0 ports on the front and back, one of which is directly next to the power plug. I need to look into this because I may be able to use my 140W USB-C wall charger to power this PC through its USB-C 4.0 port instead of using the larger laptop-style charger brick and cable that it came with. I attached some benchmark results, including one from CPU-Z showing this PC's processor is slightly faster in single and multi-thread testing compared to an Intel Core i9-11900K. This PC is fast, and the little LED multi-colored fan is a nice touch. The top clear lid comes off easily if you turn it counter-clockwise about 45° - putting it back on is easy too by doing the inverse. Out of the 3 GMKtec PCs I've purchased, I had an issue requiring support only once with the first PC. Their support team responded within 12 hours and quickly resolved my issue. If you're looking for something small to free up desk space but powerful enough to do anything business-related while being able to game too, then this PC is a great choice for you. I purchased their next model down, the GMKTec NucBox K8 Plus, to run in our conference room at work, and it handles large assemblies in SolidWorks (3D CAD software) very smoothly. I know you'd be surprised at the performance at any size, but in something this small, it is remarkable. Laptop components in a mini PC form factor for the win! I'll never buy a huge tower again. ... show more

  • Very Powerful Mini PC Very Powerful Mini PC
Wireless connectivity is really good, on initial setup I did not connect to the internet until Windows was up and running for about an hour. The speed of this Mini PC 7640HS is ridiculously good. Setup was easy with the Windows 10 that came supplied, but I installed Linux Mint and OH how smooth, Linux searched and found all drivers with no issues. Overall with all things considered, this PC has the capability to satisfy almost everyone except hardened gamers, but that is a whole different scenario. Any task you can think of, this 7640HS can handle it. 16gb of RAM is plenty for most every use case. Quite too unless you start something power consuming, then the fan spins up for a couple seconds then slows down to silence. It has been reliable for me for roughly 1 year, ... show more

  • Solid Performer, but Windows License Was Not Valid
I bought this mini PC for a client who needed a new computer for typical home use - web access, e-mail, writing documents, managing budgets, kids' homework - but with 1TB of onboard storage. Prices on memory products have shot up recently, and this model was priced attractively compared to other mini PCs with that much onboard storage, plus GMKtec was a company whose products I'd had good experiences with before, so it seemed like a good choice. I have no complaints about the hardware. Actually, I rather like the distinctive styling. This model also stands out for having a USB4 port, while others in this price range usually have USB C 3.2 ports. Most people don't have any USB C devices, much less USB4, but a little future-proofing can't hurt, right? It also has dual 2.5 Gb/sec Ethernet ports. Most buyers probably wouldn't need more than one Ethernet port, and a 1 Gb/sec (gigabit) port would be fine, but having dual 2.5 Gb/sec ones is interesting and might be helpful for some niche uses. The most curious feature of this model is the OCuLink port. I mostly see OCuLink ports on higher-end mini PCs whose manufacturers want to make it possible to use them as true gaming PCs; the use the OCuLink port to connect a dock that holds a real video card. It seems a bit odd to me to include OCuLink in a mini PC that doesn't aspire to such high performance applications, but it doesn't hurt, either. (If you look up OCuLink, you'll see that in theory, it can be used to attach other high-speed peripherals, but in practice, I've only seen it used for attaching high-end video card docks, specifically to mini PCs.) One notable thing lacking with this mini PC is a VESA mounting kit. Most mini PCs include a kit to enable you to mount the mini PC on the back of a monitor with VESA screw holes, monitor mounts or even just a wall or a desk. Not only does the GMKtec NucBox M8 not come with such a kit, but there is no provision whatsoever on the mini PC to work with such a kit. It's simply intended to sit on the desk, maybe under the monitor or even hidden in an alcove or a drawer, and stand on its feet. This isn't an issue for me, because most of my clients find it more convenient to have their mini PCs sit on the desk under the screen, where they can easily see and reach the power button and USB ports. Speaking of USB ports, this one has four Type A (regular flat) USB ports. One, on the back, is USB 2.0, and the rest are USB 3.2. Setup is the textbook Microsoft Windows 11 OOBE (Out of Box Experience) with one exception: GMKTec has customized the OOBE to let you click on an "I don't have Internet" link on the screen that lets you connect to a wi-fi network. This makes it easy to set the computer up with a local user account rather than a Microsoft account. In fact, they encourage you to do so via a sticker that they've placed over the Ethernet ports. The sticker has a message printed on it that suggests that you set the computer up BEFORE you plug in any Ethernet cables. I wholeheartedly approve, as most of my clients prefer to have their computers set up without a Microsoft account. Of course, if you want to set your computer up with a Microsoft account, there's nothing wrong with that. Just go ahead and remove that sticker on the Ethernet ports and plug in your network cable, or connect the mini PC up to your wi-fi network when the setup wizard lands on that page. I did discover one problem, for which I subtracted a star: my GMKtec NucBox M8 shipped without a valid Windows license. That is to say, it had Windows 11 Pro installed on it, but Windows wasn't activated. Since I'm a professional IT consultant who charges for his time, and the time spent setting up a new computer for a client is worth more than the cost of a Windows license, I decided to simply purchase a Windows license for the mini PC rather than send it back or work with GMKTec on this. If this happens to you, and you don't have paid time invested in your computer setup, then I would recommend you contact Amazon for resolution. ... show more

  • Surprisingly powerful and smooth performance in a compact size
I’ve been using this GMKtec mini PC with the Ryzen 7640HS (upgraded from 6800U), 32GB DDR5 RAM and 512GB SSD for a few weeks now, and I’m genuinely impressed with its performance for the size. Setup was quick and straightforward. It booted up fast out of the box, and the system feels very responsive. The 32GB DDR5 RAM makes multitasking smooth. I can run multiple applications at once without lag or freezing. Load times are noticeably fast thanks to the SSD. I primarily use it for gaming and general productivity, and it handles both really well. Graphics performance is surprisingly strong for a mini PC. It runs modern titles smoothly at medium to high settings without overheating. The fan noise is present under load but not distracting. I also appreciate how compact and clean the design is. It doesn’t take up much desk space, which is perfect for smaller setups. Connectivity has been solid so far, and having dual display support is a big plus for productivity. For the price and specs, this mini PC delivers excellent value. It’s powerful, efficient, and perfect if you want strong performance without building a full-sized desktop. Highly recommend if you’re looking for a compact but capable system. ... show more

caught this mini pc on sale for $370. so far so good, i’ve played many games, sims 4 (modded), all the grand theft autos, south of midnight & a few others no issues. i’m only giving 4 stars because i don’t have enough storage alone. i did already have an external hard drive but i thought it came with more storage space. it may be because of my sims mods. Sometimes it does get loud with the cooling fan but it doesn’t last long. for the price i got it im pleasantly pleased. ::::::UPDATE:::::: this thing is an expensive pos, it crashed in the middle of me playing the new 007, screen started glitching, i was told to reinstall windows & it won’t read my USB. then when i get it to read the USB it says it doesn’t have the drivers needed to set it up. I’ve ran into every issue. right now it only loads into BIOS. I reached out to customer service they say it’s a bad SSD. & I have to remove the SSD and send it to them on my own dime.
