GMKtec K12 Gaming Mini PC Oculink AMD Ryzen 7 H 255 (Upgraded 8745HS) 32GB DDR5 RAM 512GB SSD, Desktop Computer Radeon 780M Graphics, 3X M.2 2280 Storage Expansion, Dual NIC 2.5G, HDMI 2.1, USB4

This is a very neat little box of a computer, and if you know what you plan to do with it, I think it's a pretty good value. Basic setup is extremely simple, literally just plug in your mouse/monitor/keyboard and the power supply and turn it on. It booted with zero issues into the normal Windows 11 setup. For some reason the manufacturer recommends that you do not use a LAN cable when you first start the computer, but I was never planning on using it on anything but wifi, and it worked fine over wifi, so that is not a problem for me. Although I am planning in the future to install Linux on this machine, I was grateful that it came with minimal Windows 11 bloatware (just the windows standard stuff). Although initial setup was very fast, as soon as it connected to the internet it discovered that it had a year's worth of Windows updates to install, which takes a while, so the second time you restart the computer, expect it to go through a long update process (10-15 mins). I had no trouble hooking up Bluetooth peripherals (in my case a controller). If you are planning to use this computer for general purpose web browsing/word processing/light home server use/etc, you will have zero problems. For general purpose tasks, this computer is great. It's extremely snappy when browsing the web, downloading files, and running programs like Steam or Discord. I think advertising this as a gaming PC is a bit of a stretch-- there's only so far integrated graphics will get you, and I suspect this computer will suffer if you try to run any truly top of the line games on it. It is great for older games, or lighter indie games. I tested it on Fallout New Vegas and Celeste and it had zero issues whatsoever. I ran a benchmark test and it performed predictably poorly compared to computers with dedicated graphics cards. You can get a little more juice out of this machine by changing the allocation of VRAM in the BIOS. It's by default set at 3GB, but I went in and bumped it up to 8 (see the options in the pictures). After doing that, I didn't notice any performance dips from reallocating away the regular RAM. The 32GB this machine comes with is very generous. Even when I was trying to stress-test this machine, it was very quiet, and putting my hand on the top of the case, it never produced a ton of heat. The best way I could describe this machine is unobtrusive-- it's really small and could easily be mounted beneath a desk to completely hide it away. The power supply it comes with is almost the same size as the computer itself. The computer comes with a mounting bracket that I think is intended to be used to mount it to the wall. My one grumble is that the 1TB of onboard storage will run out pretty quickly if you're a person with a large media library like I am. I am not sure how upgradable the storage is, but I guess I can always just attach an external hard drive if I need more storage. The display options are HDMI and DisplayPort, which is fine. I wish the audio jack were on the back of the box rather than the front, but it is what it is. It comes very well packaged, works right out of the box, and performs exactly as expected. If you have a need for general purpose computing in a small form factor, this will serve that need.

This is specifically for the K12 with the Ryzen 7 H 255. Honestly, not a bad deal. The CPU is pretty good for its class, and has very acceptable integrated graphics. The H 255 is seemingly only sold to the chinese market, has no real documentation officially (as of the time of writing), and is essentially a recycled die from better chips that didn't meet the cut so to speak (at least as far as I can find), but I don't see any of those as a real problem; die recycling is perfectly fine if it actually works and is stable, and AMD is usually pretty good at the latter... and it makes me feel a little better that AMD can save something that would otherwise end up being e-waste. Despite the borderline unofficial nature of the CPU, I have not experienced any performance issues, instability, or crashes of any kind after a few weeks. Note that I updated the BIOS and microcode immediately after receiving the unit, and I suggest everyone do the same. The unit itself is from GMKtec, which is a chinese company. However, there were some (good) surprises in the box that tells me they actually cared about the end user experience, though possibly only just enough to make sure that the average joe blow didn't immediately return it because they got pissed off at something that would honestly be Microsoft's fault (eg. the horrendous OOBE for Windows). I choose to believe they actually care though, and somewhat reinforcing that, my email to them was answered the next day (I'll get to what the contents of that was later). The specs of the unit, aside from the CPU which is pretty good itself, are actually darn incredible. OCuLink is a quasi-rare connector, but an *extremely* welcome one! That significantly improves the unit's lifespan and enables mostly modern gaming, provided you genuinely do the research into how to use it (remember, don't plug or unplug it when the PC is on!), though it can already handle light-medium gaming with just the integrated graphics. Though I have not tried the OCuLink port yet, I have no reason to believe it doesn't work or anything like that. USB4 is also extremely welcome, and I can confirm that it not only works, but it follows best practices of how to implement the protocol. Since the port does do PCIe tunneling, it should work with all Thunderbolt 4 appliances out of the box. GMKtec could have taken the cheap way out and omitted this detail, but they did not. Absolutely incredible to have both of these available. There are also, seemingly (I have not opened the unit up yet, no reason to), three M.2 slots, one at Gen4x4 and two at Gen4x2, which is perfectly fine in terms of speed and great in terms of how many slots they offer. I cannot think of any other mini PC with this level of overall connectivity. You lose out on some external USB connectors that would otherwise be present, but USB4 seriously more than makes up for it. The dual 2.5G LAN ports are just the whipped cream on top of all this. Though, not all can be as good. There is no S3 power state support in the firmware, so you're stuck with shutting down the computer, hibernating it, or relying on Microsoft's absolutely abysmal "implementation" of sleep in the form of modern standby (S0). This was confirmed in my aforementioned email to GMKtec's support. Oh well, I have the whipped cream but miss out on the cherry. This may be an oversight on GMKtec's part, but it may also be difficulty getting S3 implemented with OCuLink. Don't know exactly how that works. I'm tempted to knock a star off for this, since S3 is a very, very nice power state to have available, but it's something I'm personally not terribly concerned about, especially with everything else so good. Please, if you're reading this GMKtec, add it in a BIOS update! Would love to see it! There may also be an issue with the TPM, specifically in regards to when the firmware tells the OS to initiate S0 sleep (eg. from the power button short pressed). In such an event, when the computer resumes from S0 the TPM will either fail or lock up. This may be an issue with Windows, or with the TPM, or with just my unit, and it requires a reboot to clear it up. Either way, my way around it is to leave the unit turned on or to just shut it down, but again it's not a concern for me personally, and YMMV. Overall, I would recommend this unit. Though I have not opened it to inspect the internals, nor tested the OCuLink connector yet, I see great value in this unit, and I imagine I will keep it around for a very long time, getting significant usage out of it. I would give it 4.5 stars if that were possible, but for Amazon I will leave it at 5.

As a PC enthusiast since the dial-up era, I’ve built my share of rigs to fuel epic Command & Conquer: Generals and Zero Hour sessions. I’m not chasing high-end FPS titles—give me base-building and Shockwave tank rushes at 60fps any day. The GMKtec K12 Gaming Mini PC, with its AMD Ryzen 7 8745HS, 32GB DDR5, 512GB SSD, and Radeon 780M graphics, has become my go-to for strategy gaming and everyday tasks. Here’s why this tiny titan earns my nod. This thing is small—think hardcover book size—yet it’s a beast. Setup was a breeze; Windows 11 installed without a hitch, dodging Microsoft’s TPM 2.0 roadblocks. I went local user mode for privacy, and it just worked—no workarounds needed. The K12’s quiet operation is a standout; even during intense Zero Hour GLA campaigns, the fans barely hum. It’s a far cry from the roaring towers of my past, perfect for late-night gaming without disturbing the house. Performance? Stellar. The Ryzen 7 and 32GB DDR5 chew through Generals and Zero Hour at 1080p, delivering silky-smooth battles and fast load times thanks to the NVMe SSD. The Radeon 780M handles particle-heavy Scud Storm effects flawlessly. I’ve also dabbled in Age of Empires II Definitive Edition—high settings, no lag. Multitasking is effortless, with browser tabs and Discord running alongside game sessions. Three M.2 slots and dual 2.5G NICs scream future-proofing, though I’d grab a USB hub for extra peripherals. Downsides? The port selection (HDMI 2.1, USB4, etc.) is solid, but heavy peripheral users might need a dock. Thermals are great, but place it in a well-ventilated spot for marathon sessions. At roughly $500, it’s a steal for the power. For C&C fans like me who want a compact, quiet rig that crushes strategy games without the hassle, the K12 is a winner. Five Stars—ready to command and conquer.

I've had a Intel NUC with a Core i5 for a little over 6 years but it was starting to show it's age a bit. One of the ram slots died, it would not boot if I had any ram installed in the second slot. The CPU fan was also wearing out; 3rd party options that I tried were less than stellar. So after dealing with those issues for a little over a year, I decided it was time for a replacement. It was a good pc but it's time had come. Wanted to stay with a small form-factor pc for various reasons. After checking out other options that are available, I settled on this NucBox K6 from GMKtec. It has a Ryzen 7 7840HS cpu, 32 GB of DDR5 ram and 1 TB NVME drive. I added a spare 1TB NVME drive I had to double my storage as well. Small footprint, supports 3 monitors, option to upgrade/replace components as needed with 2 user-serviceable slots for both m.2 drives ram. It's also fairly easy to take it completely apart for cleaning the CPU fan. The auxiliary case fan is a standard 40mm x 10mm pc fan; that will be simple to replace when/if the fan dies. Ticks all the boxes for me. After working with this for over a month, I've had no issues. There was no extra bloatware installed out of the box that I could find. Windows 11 has been running just fine with updates on. I do a little bit of everything with this computer: I've ripped several hundred DVDs and Blurays (with an external Bluray drive and MakeMKV) re-coding said rips with Handbrake for our media server. Some video editing with CapCut. Some light gaming. FreeCAD for designs for my 3d printer. Photoshop. Inkscape. This computer runs circles around my old IntelNUC. All that said, one thing I don't like about this computer is that there is only one USB C port on the front. The USB C port is what is used for the 3rd monitor hookup. I did not want a cable sticking out of the front for this, so I took it upon myself to address this issue. I designed a new top to replace the top from the factory. It houses a short USB C extension cable with a panel mount jack for ease of installation in the new upper housing. Works great. I can have everything plugged in to the back with minimal excess on the front. The extension plug is also loose enough in the new extended lid to unplug and move aside if I need to plug something in to the USB C port without having to take the new housing apart. I didn't print it with the best settings and it wound up being a little bit taller than I'd like but works for my needs now. I saw another review complaining that the AMD Ryzen 7 PRO 6850H is not running at the speed listed. The listing on Amazon states 4.7ghz, and his is showing it running at 3.2ghz. The speed listed on the Amazon listing is the turbo speed. If you check AMDs website on the CPU you'll see it's normal speed listed at 3.2ghz and it turbos up to 4.2ghz. This CPU is running at spec per AMDs webpage. That is not the CPU that came with mine but I wanted to share that info to avoid confusion. The CPU in mine runs to AMDs specs with no issue. Very happy with my purchase, I hope to get many years of use out of this.

Good (and fast) product, however ... if you are installing a Steam Deck alternative like Bazzite then expect to get down in the weeds with a little Konsole work. Actually, everything is quite simple. It just needs tweaking. The biggest problem ... of all things ... was the 3.5mm jack! Note: it is TRRS 3-ring. Most likely you will get no audio there, even on a TRRS jack! I went down a rabbit hole of alsactl settings only to find out my USB 2.0 mini-DAC fixed the no audio through headphones issue. I could only tap the HDMI digital audio through my monitor speakers! Now, it's good through the mini-DAC. Bazzite installs GREAT! No problems. Setup your BIOS first. I Clonezilla'd the disk with Win 11 and tossed in drawer. Bazzite runs great and if I need an upgrade, most things are possible with the OcuLink and spare memory and hd slots. Also note: the front ports are electronically noisy for BT and 2.4G. You might have issues. Move to the rear ports. BT is out for my mini-keyboard but 2.4G works fine. All in all, a good buy. I was skeptical of the 'ease' of installation claims. Not the easiest and not the hardest. Typical weird Linux stuff. Bypassing and configuration usually fixes things. Is it the best solution all the time? No, but it gets you into Steam just fine! Runs fast in Performance Mode. Fan runs constantly, so switched back to Balanced Mode. We'll see how some later games play. Recommended!

Absolutely love it,its powerful enough to play games a lot of games, i had emulators from PS3 to Switch working on it along with a some high end gaming at lower setting, but paired with an AMD 7600M XT egpu, it can handle most games at 1080p 60fps. It's compact and quiet with 2 big fans to keep it cool. Highly recommend if you want something cheaper and smaller that a desktop

Six months ago, I picked up a GMKtec mini PC, all jazzed up by its USB4 hype. Spoiler alert: it turned out to be a bit of a flop. Despite friendly tech support, they couldn’t solve my issues, and after venting on Reddit, it became clear that its USB4 was barely scratching the surface of compatibility. None of my gear worked with it, which was a real letdown. Fast forward to my second attempt, and what do you know? It's like night and day: Ubuntu 24.04 Magic: It fired up and ran like a dream. I zipped through backing up the entire 1TB NVMe drive in a breezy 35 minutes, capturing every single bit of the boot drive. Windows 11, Clean and Lean: It arrived with a super clean installation of Windows 11—absolutely no bloatware! I appreciated being able to skip the usual Microsoft account rigmarole and set up a local account right off the bat. Keeping Cool on Power: Power usage was impressively modest, hovering around 24 watts on average. It dipped to a low 12 watts and could spike to 77 watts when pushed to its limits. USB4 For Real This Time: This time, the USB4 genuinely delivered. Regular USB3.2 speeds were decent at 950MB/s, but USB4 blew them out of the water, rocketing to about 3200MB/s with my USB4 enclosure. eGPU Adventures: The real test was getting my eGPU to cooperate. After about 45 minutes of tweaking and using the DDU utility to clear out AMD drivers, my AKiTiO Node Titan with a Nvidia 3060 kicked into high gear, boosting my gaming fps from a solid 72 on the integrated 780m to a whopping 174 with the Nvidia. While I've heard that USB4 doesn't provide the full bandwidth of a direct PCI bus, this performance is more than satisfactory for my needs. Video Production Smooth Sailing: All my essential video tools like ffmpeg and Davinci Resolve ran flawlessly. I haven’t fully benchmarked the before and after yet, but I'll post an update when I do. One Minor Quibble: Although I appreciate that all the drivers and even OS images are readily available via Google Drive links, the process of updating the BIOS and drivers could be more user-friendly. Bottom line, this new unit is leaps and bounds ahead of the first one I tried. It's met all my needs and more with solid performance and genuine, god-fearing USB4 action. If you're in the market for a mini PC that punches above its weight, give this one a whirl!

EDIT - 4/18 Things seem to work well now, also I was not able to get Debian installed but I think Ubuntu Mint was working ok. Marvel Rivals when hard to compile shaders and crashed when started with a ton of crap in the background but after a reboot was running at 40% CPU, 80C and was too busy playing to catch GPU temp/usage. Ran very smoothly but I would guess 45-60fps tops. So this seems to be a great device for my needs. You probably won't run Cyber Punk on Ultra here but I have heard you can host a private WoW server with 500 bots running as well as run 3 different browsers with 1 running YouTube/Prime movies and another running Twitch and the system utility stays at about 40-50% CPU usage and 70-80% RAM usage on a 32 Gb Ram machine, CPU hit's 65-70C and GPU hit's 55-60C. No issues with lagging components unless it is internet/waterfox related. I will try out Marval Rivals and a few other FTP games and update this in a month ish. I will also try to grab power consumption a little later as well I just had a super customer service experience(see below) that was in touch multiple times through out the issue so wanted to provide feed back now. I have another mini AMD PC and I highly recommend installing the AMD Adrenalin software as I had Video issues on my other system before installing the updated CPU drivers. I did install that when first getting the system and have not had the same video issues(also stopped getting video issues on the other system so I put that on bad initial drivers from AMD). PREVIOUS ISSUES I have no clue if it works. Came with a bad SSD. Customer service is pretty responsive but "Estimated delivery time: 8-13 working days." so I have 2 to 3 weeks before I know if the product works. Going to order a replacement SSD and will install Linux on it to make sure it functions and everything seems to work ok.

Ich nutze den GMKtec Mini PC mit Ryzen 5 6600H unter Windows 11 und bin bisher sehr zufrieden. Das System läuft bei mir äußerst stabil und zuverlässig mit 2 Bildschirmen. Auch im täglichen Einsatz gab es bislang keinerlei Abstürze oder andere Probleme. Besonders positiv überrascht hat mich die Leistung: Neben Windows 11 auf dem Host-System betreibe ich zusätzlich eine Hyper-V-VM mit Windows 11, die parallel läuft. Selbst dabei arbeitet der Mini-PC flüssig und ohne erkennbare Leistungseinbußen. Ein kleiner Kritikpunkt ist die Treiberinstallation nach einer Neuinstallation von Windows. Einige Treiber werden nicht automatisch erkannt und müssen manuell von der Herstellerseite heruntergeladen werden. Die Navigation auf der Webseite ist etwas unübersichtlich und die Suche nach den passenden Treibern könnte einfacher sein. Positiv ist jedoch, dass der Hersteller auf seiner Webseite auch ein komplettes Windows-Installationsimage inklusive aller benötigten Treiber bereitstellt. Damit lässt sich das System bei Bedarf problemlos neu aufsetzen. Fazit: Ein leistungsstarker, kompakter und stabiler Mini-PC mit sehr gutem Preis-Leistungs-Verhältnis. Insgesamt eine klare Kaufempfehlung.

Este mini PC tem funcionado muito bem neste um mês que tenho usado ele. Comprei por 4.500, preço bem mais baixo do que as opções com o processador 8845HS. O processador AMD Ryzen 7 7840HS é competente e praticamente idêntico ao 8845HS, com 8 cores rápidos, e não esquenta demais (temperatura máxima permitida é 100°C, não passa de 85°C em uso pesado aqui), devido ao bom sistema de esfriamento. Alguns compradores reclamam do barulho dos ventiladores internos (tem dois, um pequeno em cima e um maior embaixo), mas a minha unidade é bem silenciosa. Está rodando uns programas para mim que usam 50% do processador e cerca de 73°C o dia todo, todo dia (24/7). A placa de vídeo é a 780M, a mesma do 8845HS, e é bastante potente para uma placa integrada, suportando bem jogos médios e alguns pesados com configurações mais modestas. A BIOS dessa máquina permite alterar a quantidade de memória separada para a placa integrada. O SSD de 1TB é rápido, os 32GB de memória são suficientes para minha utilização. Vem com o Windows completo instalado e funciona bem nos meus testes, mas uso com Linux e tem sido estável. A única reclamação que tenho, que é um pequeno detalhe, é que o sistema não informa a velocidade de rotação (RPM) dos ventiladores, os softwares que mostram esse dado não suportam o sensor instalado. Atualizarei esta avaliação quando tiver mais dados sobre durabilidade.

Harika bir bilgisayar ofisimde kullanıyorum aynı markadan 3. ütünüm.

Excelente, necesitaba una PC con con Xion Oculink para conectar una GPU externa y mi vieja PC no tenía ni USB 4.0, esta PC tiene lo que necesitaba.

IT WOULD BE NICE IF THERE WERE WIDER UPGRADE OPTIONS.
