I bought this PC to replace my Atom N150 and needed a small form factor PC For basic, affordable laptops or Chromebooks: Intel Processor N150 is sufficient. For performance, multitasking, and future-proofing: AMD Ryzen 7 7730U is far superior. The KAMRUI Mini Gaming PC, E3B Mini PC equipped with the AMD Ryzen 7 7730U stands out as a compact yet powerful desktop solution for both office and home use.

When I opened the box, I found, besides the mini PC, a few accessories like a VESA mount (M3), a grounded AC adapter, a short HDMI cable, and a cable to add an additional hard drive, but I didn't see any instructions on how to install the hard drive. When it came to the VESA mount, it included screws, but I noticed they were too small for my large-screen Google TV. It fit exactly on my 19-inch display, but when I wanted to mount it on my Google TV, I had to use larger screws to make it work. I measured the dimensions of the case myself, and they’re about 131 x 131 x 50 mm, or roughly 5 x 5 x 2 inches. The case is made of hard plastic and has a power button on the front left corner that lights up red when it’s turned on. On the front, I have two USB 3.0 ports, a Type-C port that handles both data and video signals, and a standard 3.5 mm audio jack that works with both microphones and headphones or speakers. On the back of the case, I found two USB 2.0 ports, an HDMI port, a DisplayPort (DP), and two Ethernet ports - one for 1 Gbps and another for 2.5 Gbps. There’s also a Type-C port on the back, but it’s specifically for connecting the AC adapter to power the PC. With three different video signal ports available, I can connect up to three displays, although I’m currently just using it with my TV. I can read on the power adapter of the mini PC that it delivers at most 64.98 watts (19 volts, 3.42 amperes). It has a grounded plug and according to the information printed on it, it’s UL listed, CE certified, has the UKCA marking and it’s approved by the FCC. So, I guess the power adapter should be safe. When I touch the power adapter’s housing, I don’t feel any excessive heat - it's just warm to the touch. I can access the BIOS by pressing the DEL or F2 button repeatedly immediately after turning on the PC. Alternatively, similar to my laptop, I can press the F7 button to first enter the boot menu, and then select ENTER SETUP to access the BIOS from there. According to the BIOS, The mini PC is equipped with an AMD Ryzen 7 5800U processor. The PC is almost completely silent. I rarely hear anything. Also, It took just a few seconds to boot into Windows 11 during the initial setup. I didn’t encounter any bloatware in the pre-installed Windows. Getting back to the BIOS, I noted that Secure Boot is enabled. The system is configured in UEFI mode with the NVMe SSD set as the primary boot drive. The TPM 2.0 module is enabled, with security features such as SHA256 PCR Banks supported, adding an extra layer of protection to the system. When I first connected it to my Google TV, which I use as a display, I noticed that the image was cut off at the edges. To resolve this, I accessed my TV’s settings by clicking the settings button, then navigating to the Picture section. From there, I went into Advanced Settings and scrolled down until I found PC Mode. Enabling PC Mode instantly fixed the problem, and the display fit completely. The boot time ranges between 3 to 7 seconds, depending on the tasks or programs that I left running beforehand. Curious about the internal components, I opened up the chassis. The screws are hidden under the rubber feet at the bottom of the unit. Once opened, I saw the mini PC is equipped with two 16 GB DDR4 Lexar RAM sticks, giving a total of 32 GB of memory. The RAM operates at 3200 MHz, which I think is fast enough for responsive multitasking. For storage, the PC uses a 512 GB Apacer M.2 NVMe SSD. NVMe SSDs are known for their speed, and this model doesn’t disappoint me. The SSD provides read speeds of up to 3000 MB/s and write speeds of up to 2000 MB/s. I guess these speeds contribute to the overall system responsiveness, from booting up Windows to launching heavy applications in seconds. I use the mini PC for media streaming, productivity software and video rendering. I regularly use LibreOffice for document creation and editing, and it runs without any lag. In addition to productivity software, I use the PC with GIMP, a photo-editing program that can be resource-intensive depending on the size and complexity of the files being worked on. Even when I'm editing high-resolution images, I haven’t experienced any lag or slowdowns. I also use KDENLive, a video editing software and the PC handles video rendering without issue. I rendered a short video clip in 1080p, and while this task can be taxing for many systems, the mini PC finished it within 6 minutes. For media streaming, I used it to watch 4K content through platforms like Netflix and YouTube. The streaming experience was smooth, with no buffering or lag, even when switching between tabs in a browser or running other programs in the background. The device's AMD Radeon Graphics renders high-quality video without any stuttering. To get a clearer picture of the mini PC’s capabilities, I ran several benchmarks using CPU-Z, OpenHardwareMonitor, and HWiNFO. The benchmarks confirm the mini PC is powered by an AMD Ryzen 7 5800U, with 8 cores and 16 threads. I learned this processor operates at a base clock speed of 1.9 GHz but can boost up to 4.45 GHz during high-performance tasks. According to the results from CPU-Z, the CPU runs normally even under heavy load. During demanding tasks, such as when I’m video rendering and multitasking between several productivity applications, the clock speed stays within the 3.5 GHz to 4.4 GHz range. During the benchmarking, the CPU stayed relatively cool, with temperatures hovering around 55°C to 61°C. I monitored the thermal performance through OpenHardwareMonitor, and the CPU package temperature rarely exceeded 61°C, even during prolonged use. The 32 GB DDR4 RAM, running at 3200 MHz, allows me to do multitasking and seamlessly switch between programs. Even when I’m running several resource-heavy applications at the same time, such as GIMP, KDENLive, and LibreOffice, the system doesn’t slow down. According to the resource monitor, the 512 GB Apacer NVMe SSD reaches read speeds of up to 3000 MB/s and write speeds of up to 2000 MB/s. I can confirm that as file transfers and application load times are quick and hassle-free. I’ve been using the mini PC over a month and so far the mini PC has been doing my everyday tasks. Whether I am browsing the web, streaming 4K videos, working on documents in LibreOffice, or editing photos in GIMP, the system handles it all without any freezing or stuttering. The unit is very silent even when I’m running more demanding tasks.

Before I purchased this I had a Ryzen 7 2700 Desktop Computer that I built myself about 5 years ago. But the case was large and heavy. I live in an RV so I'm trying to downsize where I can. When I compared this unit to what I had the research I did said this one would be just slightly faster because of it's newer architecture. My other Ryzen was a desktop processor and this one is like a laptop based processor. This thing is so small, has twice the RAM I used to have and is running great. I still can't believe how small it is. I may buy another one of these in the near future for my Home Assistant OS. I'm very happy with this and love the small size!

Bought it as a portable computer for a clone hero setup and it works pretty well. I stress tested it with 4 player expert with bot turned on and the highest usage it hit was 102% (measured with hardware monitor) on a 144hrtz 1440p monitor. Temps never hit over 80°. All in all this is a very good purchase for light to medium gaming and the support team was very helpful when I had issues.
