Great deal, but mine came with a used SSD
Pros:- Small- Powerful (8 Zen4 cores, 16 logical CPUs, Radeon 780M graphics, HX power spec)- (Relatively) low power consumption from being a laptop CPU (Though the HX is not as efficient as the U version)- Comes with a good amount of good quality RAM from a name brand- 2x 2.5G nics- USB4 port (haven’t tested it out yet, other reviewers had issues)- Good cooling- Quiet at idle (YMMV)Cons:- Came with a moderately used Lexar SSD- Windows 11 (wiping that put even more write cycles on the SSD)- A U power spec option or BIOS support for lowering TDP would have been nice for lower power consumption- No SATA support- Ethernet controllers are Realtek, not Intel- Wifi also not IntelThis is just an initial review, but out of the box I noticed that the 1TB SSD that was included in this GMKtek K6 mini PC had logged about 86 hours of usage in SMART, as well as over 8TB written and 7TB read on this 1TB Lexar SSD. That seems like a lot more than initial imaging and burn-in to me. Over 8 full write cycles for every memory cell will have an impact on the SSD’s lifespan. I am only using the included SSD as a supplement to my main SSD, so it’s not a big issue, but buyer beware! Also, the SSD did come with an extra heatsink pre-installed. That may improve the longevity of the disk enough to compensate for a lot of the usage. I removed it from the included drive and installed it on my 3rd-party drive instead since I use that one more.Overall, this system seems to work well. I wiped Windows 11 and am using proxmox on it. The Ryzen 7840 CPU is really great for my purposes as a VM server / AI host. In July 2024 I got this for $509. With the 32Gigs of ram and a 1TB SSD that is functioning, at least, it’s a really amazing deal. Similar machines from other manufacturers cost hundreds more without the RAM or SSDs, so I’m not going to complain too loudly. In fact, I think it’s a great deal from Amazon and GMKtec.Time will tell how well this machine holds up, but the construction seems solid, the cooling seems to be well-designed for this form factor with a fan for the CPU being pretty standard, but a second fan for cooling all the other components is a nice addition that you don’t see in some competitors. I will update this review with any developments.

Good mini pc for the money.
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.

(K12 – Ryzen 7 H 255) Great value, exceptional hardware and connectivity
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.

1 star Bad SSD 3/24, 4 to 5 star updated review 4/18 .
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 ISSUESI 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.

GMKtec K12 Gaming Mini PC: A C&C Generals Fan’s Compact Powerhouse
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.

Amazing mini PC!
Ryzen 7 PRO 6850H model.Very fast CPU. GPU is nice too considering the price. Runs cool on balanced setting. Works great with Linux and Windows11. I haven’t tried it yet with oculink (PCIe 4x). All I could ask for is a PCIe 16x port for connecting an external discrete GPU via a ribbon cable.

Powerful little machine, but finicky with egpu. Great support.
This is a great mini PC for the price. By itself it can be used as a small but powerful office or development machine, or even for light gaming. However, when you throw in an eGPU it readily opens up alerting you to do much heavier lifts, like video editing or regular gaming.The only I don’t give it 5 stars is that despite it having a USB 4 port, I was unable to use my Razer Core X with the device. Nothing I could do wroth get it detected. I reached out to support abs they were very helpful. I exchanged emails with Julian, who was very knowledgeable and walked me through several rounds of trouble shooting. In the end we determined something about the Razer Core X and the USB4 implementation on this device is incompatible.I was able to get my hands on a different eGPU – and AD-GP1. This eGPU worked perfectly. It was simply plug and play since the AMD drivers were already installed.

Perfectly capable little computer, great form factor
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.

Outstanding Value, Perfect for Everyday Use (not serious gaming)
I am so delighted with this Mini PC that you might think I’m biased. So, to be clear I paid for this myself and I’m not claiming it’s the best Mini out there but for my needs it is the best value. For a start, calling it a “gaming” PC is an exaggeration. It’ll play basic games but nothing serious like “MS Flight Simulator” because it uses onboard graphics, NOT a discrete GPU. However, I have a Playstation and an Xbox for games. Why would you play games on a PC monitor and not on your giant 4k TV?I use my PC for MS Office, as a Media Server, for video editing and for browsing. I have it hooked up to 3 monitors (4k hdr, 1440p, 1080p) and the graphics are stunning. The internal NVMe SSD is very fast; I was easily able to add an additional SSD in less than 3 minutes.The Oculink port is a bonus but, honestly, adding an external video card would cost twice as much as the PC so no thanks!I’m on my fourth NUC; there are so inexpensive that I can afford to upgrade every 3 years and I would definitely buy GMKTec again.
