GMKtec K12 Gaming Mini PC AMD Ryzen 7 H 255(Upgraded 8745HS) Desktop Mini Computers Radeon 780M WiFi 6E/BT5.2, USB-C, Barebone

Great product and fast shipping.
I only worked ptm7959 thermal pad replacing
It shows great cooling, very lower temperature of cpu during cine r23 multicore bench testing.

I have received the correct product.

It works well.

With a DDR5 4800 16x2 configuration, the Cinebench Multi score is 16,000 points and the Task score is 2,734 points.



It definitely controls heat better than the old can-shaped mini PCs, probably because it has dual cooling.

I'll have to try it out and then think about whether to work with the PTM 7950.

一応動作確認も済み、現状異常無しとなりました。 説明通りのとてもコスパのいいベアボーンモデルです。 ただ、同じ仕様の物を日本の人が購入する場合、コンセントプラグはアダプタを買うより少し奮発して、画像なようなeu式の電源タップを一つ購入しておく方が良いと思います。 アダプタはやはり抜けやすいけど、電源タップだとガッチリしてますからね。 付属のacアダプタは100～240vの物なのでコンセントプラグだけきちんとしたら普通に使えます。

Wow... PCs are pretty good these days.
I tried to make use of my 9-year-old Asus laptop in any way possible, but eventually gave up and upgraded to this one. I got it for 580,000 won including RAM and SSD, and after a simple assembly, I'm using it now. It's seriously fast! I set it to the minimum with 8GB of RAM, and it's surprisingly fast. It's really fast. I don't play games, so I don't know about game performance (but they say the AI will be fast). Anyway, the satisfaction level is excellent. Ah, the build quality of the device itself is good. BIOS, hardware, finishing quality, etc... I've never had any issues with any of these.

Since it's a barebone model, I prepared the SSD and RAM in advance, and it was installed well and worked well. The built-in graphics are also excellent, but when I connected the 4070 Ti SU via an OC link, the performance was similar to or even better than a 5700x DDR4 desktop. I made a good choice.

Best value for money, also suitable for eGPU setup via OcuLink

It was delivered 5 days after purchase.
I bought it during the Singles' Day event and liked it so much that I ordered another one.
Fortunately, I had an extra SSD and memory, so I installed them right away and am using them.
It operates quietly and performs well, so I'm very satisfied.
For the time being, I think I'll only use a mini PC because the PC isn't cost-effective enough.

​ It arrived quickly after ordering. The product has a neat finish and a simple design, making it pretty.
After installing the parts and Windows, the speed is extremely fast. I bought it for office use and light gaming, but its performance is outstanding. It is the best cost-effective mini pc. Those who are considering won't regret choosing it. I will use it well!

Delivery took about a week after ordering.
I was looking to buy a mini PC during the Singles' Day event.
I wanted this model the most so I bought it right away.
I was really happy because even with the card discount applied, it didn't cost me more than $200.
Although the exchange rate has risen, it's a newly released model, so I bought it at a low price.
I'm satisfied. I reused my existing RAM and SSD, so there was no additional cost.
There is no noise and the gaming performance is excellent. It's the best.

It's incredibly fast and works well. I definitely recommend it. It's being used successfully in Korea as well. The quality is very good. Even though it only has 16GB, the program speed is impressive.

I upgraded from the 6600h and am very satisfied.
However, it's a bit disappointing that it's bigger than the 6600h.
I don't know if it's useful to have three SSD slots, but having an external graphics port is nice.
What I mainly do is open the stock window and play the Diablo series in windowed mode, and if I lower the options in Diablo 4, it runs comfortably at close to 60 frames per second.
For reference, the 6600h had 40 frames per second and the Dia3 was comfortable.

Very happy with the mini pc so far. One important note for other buyers: my unit was unstable with a corsair vengeance ddr5 kit, even though the ram passed multiple memtest runs. After switching to jedec-standard ram, the crashes stopped. The gmktec k12 bios does not expose any xmp or ram tuning options, so i’d recommend using plain jedec ddr5 rather than high-speed xmp kits.

It's quite fast for international shipping.
I'm very satisfied with the performance. Since it's a barebone model, I used the existing SSD and RAM, but the CPU and built-in GPU seem to be quite good.
Above all, I was surprised that the EU plug fit perfectly when I received it. Thank you.

Delivery was fast and there were no performance issues, but SSDs and some screws started to wear out.

Added 16gb and 512 m2, so far no issues, no freezing or loud fan noise, i love it and i hope it lasts long, definitely buying another one when rams become available
