KAMRUI E3B Mini PC, AMD Ryzen 5 7530U, 16GB LPDDR4X, 512GB SSD

Mini PC Windows 11 Pro, KAMRUI AK1 PRO 12GB RAM 256GB SSD Mini Desktop Computer Intel Celeron N5105 Processor This Mini PC is small and packed with a ton of power. WELL WORTH THE PRICE, SUPER SATISFIED I needed a small but powerful PC to help me operate my uniquely designed entertainment system, I needed a device that was browser based that would give me the opportunity to stream specific content to my video wall where I use a 2x2 TV Video Wall Processor HDMI Matrix Controller Splicer Splitter that splits the video over multiple TV’s and the Kamrui AK1 PRO fit the bill, The APK1 was extremely easy to setup and the small size was very easy to hide, It was a huge plus to have Windows 11 pre-installed, This PC is very quick and responsive, there is absolutely no lag whatsoever, I also took advantage of the empty expansion bay where I installed a 2TB SSD drive, The Intel UHD 800 along with the dual HDMI ports were a perfect fit for me because it gave me the ability to run 1 HDMI cable to my 2x2 TV Video Wall Processor so that I could stream my content, while the 2nd HDMI port ran directly to my monitor, so I was able to do my work and stream my content all at the same time with any lag at all. I was very satisfied with the wireless connectivity with the 802.11 ac Dual Band 2.4 & 5 Ghz WiFi, and everything ran extremely smooth, although I preferred to run a direct ethernet cable to the APK1 as a direct connection is always preferred when you have the chance to do so, The APK1 comes with 4 USB ports in total, 2 of them are USB 3,0 and the other 2 are USB 2.0 so there is more than enough ports to connect your USB cameras, printers or any other devices that you would be using. In the end the Kamrui APK1 is a small but extremely powerful Mini PC that can handle just about anything you throw at it, and the best part is that the APK1 is priced well below the other machines out there that offer you less, If you want top performance for a fraction of the price then do yourself a favor and take a look at the Kamrui APK1, I promise you that you won’t be dissatisfied at all, Once you see how great this machine is there’s a good chance you’ll find yourself buying a 2nd one or a 3rd one..

I’ve been using the Kamrui Mini PC for a few weeks now, and I’m absolutely thrilled with it! As someone who needs a reliable computer for both work and entertainment, this little device has been a game-changer. It’s incredibly fast—thanks to the powerful processor and SSD, I can switch between tasks like video editing, streaming, and browsing without any lag. The compact design is perfect for my small desk, and I love how it doesn’t take up much space but still delivers desktop-level performance. Plus, setting up my dual monitors was a breeze with the HDMI ports. What really stands out to me is how portable it is. I often work from different locations, and being able to just slip the Kamrui Mini PC into my bag is so convenient. The Wi-Fi 6 support ensures I always have a stable and fast internet connection, which is a huge plus for video calls and streaming. For the price, this mini PC offers incredible value—it’s powerful, versatile, and perfect for anyone who needs a compact yet high-performing computer. I couldn’t be happier with my purchase!

***UPDATE*** The customer service agent I originally contacted was fired, a new customer service agent contacted me and helped me with a replacement hard drive, I was able to easily replace the old hard drive with the new one and the PC is working again as expected. I am running Ubuntu on the new hard drive and the PC works even better than it did with windows on it. It is nice to know the company stands behind their products! I get that things break sometimes but its the customer service that matters when things happen. I am glad to say I am overall happy with my Mini PC and the customer service I received from the new agent. Only boots to bios and does not recognize SSD to boot to windows after only 4 months! I was really impressed with the mini PC out of the box, but after just 4 months it seems the hard drive has failed! PC will only boot to bios now, inside the bios menu in does not recognize the hard drive at all. I reached out to their customer service as this should be well within warranty period and they responded after 2 days asking me to run some diagnostic tests and reinstall windows, as I do not think they understood my original email to them telling it that it would not boot to windows and only to bios. I was hopeful they were actually going to help me, so I replied back with photos and explaining in further detail that I could not run the tests they wanted me to, sent them a video of the PC only booting to bios and now it has been over a week with no response, I have followed up 3 times now but have not heard anything back!

***REVIEW FOR KAMRUI AM21 -- please note which model is being reviewed as the review section contains reviews for multiple products.*** With the 10% discount, I grabbed this 32gb 1tb model at a nice price. Teardown was easy. I replaced the thermal paste, installed Bazzite for Steam gaming, and saved the Windows 11 key just in case. No issues running Steam so far in deck or desktop mode. I wish it had a second fan, the current single fan exhausts upward through the upper side-grilles but could use more active ventilation, but it's such a compact model. No Oculink port but I didn't need one. I am replacing the wifi/bluetooth card -- the current one disconnects enough to be annoying. This PC is being used exclusively as a mini Steam PC. Makes less noise than my GMKTec K8 plus. Update 12/24/2025: the wifi connection cuts in and out on occasion and so I'm replacing the M.2 wifi/bt card with an AX210. Update: 12/30/2025: installed an AX210 wifi/bt card. I previously forgot to mention that setting the front power button to the correct position for re-assembly can be tricky. If you don't the power button goes off-center with respect to the internal switch. For reassembly, make sure the case power button is all the way out (push the inside toward the case shell so the exterior button is seated as far up as possible). Pull the front case panel away, giving a little extra room for the button to seat correctly, then snap the two halves shut. UPDATE April 25, 2026: Still running great! Really impressed with how well this is running Steam. No unit issues thus far.

I have used this PC for about four years now, and it is perfect so almost all of my needs. I’m not much of a PC geek— so bear with me. I have been able to play Sim4 flawlessly, Stardew, and Minecraft. I also use this PC to perform school work, perfectly runs! My only note, is to be aware that this PC isn’t meant to run big games. I was super excited to play Palia recently— but it wouldn’t run because it didn’t have the necessary bits and bobs. That is sadly, why I’ve decided to buy a new PC and give this one to my mom. BUT— because this device ran so smoothly and performed all of my needs, I am buying a new PC from KAMRUI. I trust them, and their product was perfect. I just need a little upgrade! Thank you!!

It is a Celeron, but does the job well. The TPM 2.0 is useful because with Ubuntu 26.04, one can use LUKS encryption with it, making a nice, headless remote PC for things like Pihole, Proxmox, Docker VMs, and other items, while giving peace of mind of disk encryption. I'm using this with Docker to run FreeIPA so I have LDAP authentication at home for everything. It is a great deal (as of July 13, 2026) for the price. Caveat: The SSD is SATA. Definitely not a barn-burner, but it is more than good enough for the price, so I don't consider this a real downside. I personally wish SATA SSDs were more common, especially how expensive NVMe ones are running.

This little mini is quite capable and quiet. If you get it on sale it is a great little pc for media and light gaming. The only downside really is the included ssd. They should have included a faster m.2 drive instead. They could have done so for maybe a cost of 5-10 dollars more at most. So when I got this I wasn't quite happy with the ssd performance. I got a new m.2 and put a fresh install of windows 11(always do a fresh, clean install with a new pc) on it: I got the Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSD. (Don't worry, the Windows 11 license is unaffected by the drive change and fresh install.) Now don't get me wrong, if you're using this just as a media device the included ssd is fine. Or if you are upgrading from a really old machine that uses a mechanical drive, you'll be delighted with the included ssd drive. However, M.2 drives are just a lot faster, and now this thing boots in no time and is now really nice and snappy overall. You can definitely tell the difference. And then if you want to you can reformat the original ssd and use it for a little extra storage. I have a large external drive, so I elected to not use the orignal ssd, and keep that slot open for slightly better internal air flow. This also came with 1 stick of 16GB DDR4 RAM. If you have 2 sticks of 8GB laying around, or 2 sticks of 16 GB, that would be even better. If not, the single stick is OK. But if you want to do a little gaming, 2 sticks is a must in my opinion. Just better performance. But serious gamers obviously should build their own pc. For someone like me, though it is perfect. I can have as many tabs open in my browser as I like, watch a video, and even game a bit with older titles and lower settings. I've even played less demanding games and watched videos at the same time. It's only a couple months old, but no issues so far.

My initial review of the KAMRUI E3B Mini PC was a 1-star rating due to a complete hardware failure after five months of use. The system suffered from frequent Blue Screens of Death (BSOD) and would black out and reboot entirely whenever I attempted to play videos or handle multimedia tasks. Following my review, the seller proactively reached out to resolve the issue. They provided excellent customer service and issued a full refund for the product without any hassle. While the specific unit I received had technical flaws, the seller has proven to be highly responsible and trustworthy. As previously stated, the KAMRUI E3B Mini PC failed after five months of use, experiencing constant BSOD crashes and reboots during basic YouTube video playback. The hardware itself was a disappointment for my productivity needs. Recommended if you would like to buy this one then you can at least rest assured that the company stands firmly behind their products and takes care of their customers. My rating to 4 stars purely to reflect their customer support . Not the PRODUCT. --------------------------------------- Previous Rating and Details ----------------------------- ⭐ One Star - Complete Failure After 5 Months of Use - Do Not Buy! Initial Review: 5 Stars (Mistake!) When I first purchased the KAMRUI E3B Mini PC with AMD Ryzen 7 5825U, I was incredibly impressed. It was fast, quiet, and seemed like a powerhouse in a tiny form factor. For the first few months, it performed flawlessly, and I happily gave it a 5-star rating, feeling confident in my purchase. Unfortunately, that initial excitement has completely evaporated. After only about five months of use, this Mini PC has become utterly unreliable and is actively hampering my work. The system now faces constant, severe stability issues that make it unusable: Frequent Blue Screens of Death (BSOD): The blue screen appears with alarming regularity, often without warning, forcing my work to halt and risking data loss. Video Playback Failure (Black Screen & Reboot): This is the most frustrating issue. I cannot watch videos for any extended period—not even simple YouTube videos. The screen will suddenly go black, and the entire system will immediately reboot. This happens consistently when under any kind of video or multimedia load. Unreliable for Work: The constant crashes and reboots have made this machine completely untrustworthy for daily tasks. I bought this to be a productive workstation, and instead, it has become a source of immense disappointment and stress. Conclusion: A Product That Will Not Last My initial positive experience has been overshadowed by these critical, deep-seated stability problems. The KAMRUI E3B Mini PC with the Ryzen 7 5825U has demonstrated a severe lack of long-term reliability. The consistent blue screens and the inability to handle basic video playback without crashing strongly suggest a fundamental flaw, possibly with the cooling, power delivery, or specific component quality. Save your money and your frustration. This product will not last, and its early failure is a major letdown. I have downgraded my rating from a temporary 5 stars to a definitive 1 Star. ---------------- Previous Rating 5 --------------------- I wasn’t expecting such a powerhouse in such a tiny form factor. This one has blown me away with its performance, versatility, and value. It's my go-to machine now for both work and play. Pros : 8 cores make multitasking effortless Triple 4K display support is perfect for my home setup WiFi 6 & Bluetooth 5.2 is the lightning-fast connectivity. Super compact and easy to mount behind a monitor. Super easy installation Cons : Don’t expect high-end gaming, but light titles like CS:GO and Stardew Valley run smooth at 1080p. Great for emulators and indie games. 4K streaming is flawless on Netflix and YouTube. Overall : This mini PC punches way above its price. Quiet, fast, and shockingly capable—it’s the perfect pick for anyone needing a small but mighty desktop.

Compré esta máquina para las clases en línea de mi hijo y funciona excelente. Me gustó que tiene Windows 10 Pro y no Home como otras máquinas de precio similar. Trae el Windows pre instalado así que no es necesario invertir tiempo en eso. El desempeño es excelente para ejecutar aplicaciones como Office, Teams, Zoom, etc. Tiene 8 GB en RAM y 4 núcleos de procesador. El disco duro es pequeño, pero es de estado sólido y útil para mis propósitos.

Fácil de instalar, veloz y se ve de buena calidad. Sistema operativo Windows 11 Pro. Lo recomiendo para el hogar. Buen precio

Excelente producto, llego antes de la fecha estimada, ya la probé funcionando al 100 y muy compacta, cumple con todas mis expectativas 👍

Lo voy a utilizar como servidor en la casa, lo único que no me gustó tanto es que mantiene una temperatura de 60°C en modo pasivo.

Es muy funcional y práctica
