The KAMRUI E3B Mini PC is built for users who want strong desktop-level performance in a compact and energy-efficient form factor. Powered by the AMD Ryzen 5 7430U processor based on Zen 3 architecture, this mini PC targets professionals, students, and even casual gamers who need speed, multitasking capability, and modern connectivity without investing in a bulky desktop tower. With support for triple 4K displays, expandable memory, and WiFi 6, the E3B positions itself as a versatile solution for both work and entertainment.
At the heart of the KAMRUI E3B is the AMD Ryzen 5 7430U processor, featuring 6 cores and 12 threads with boost speeds up to 4.3GHz. Built on Zen 3 architecture, it delivers noticeably better single-thread performance than the older Ryzen 5 5500U, which translates into smoother web browsing, faster document handling, and responsive everyday computing. With a 15W TDP that can scale up to 28W, the processor balances power efficiency and performance well.
One of the highlights of the E3B Mini PC is its full-function USB Type-C port. This single port supports power delivery, high-speed data transfer up to 10Gbps, and 4K display output at 60Hz. This makes it extremely convenient for modern setups where users prefer fewer cables and cleaner desk arrangements.
The mini PC comes pre-installed with 16GB DDR4 RAM and supports expansion up to 64GB using dual RAM slots. This makes it future-ready for heavier multitasking and professional workloads. On the storage side, it includes two M.2 2280 slots, one supporting NVMe or SATA SSDs and the other supporting SATA SSDs only. Both slots support up to 2TB drives, offering plenty of room for applications, games, and media.
Graphics duties are handled by the integrated AMD Radeon RX Vega 7 GPU clocked at 1800MHz. While it is not meant for high-end gaming, it delivers reliable performance for casual gaming, media playback, and productivity tasks. With HDMI 2.0, DisplayPort 1.4b, and USB Type-C, the KAMRUI E3B can drive up to three 4K displays simultaneously, making it ideal for multitasking and professional workflows.
The E3B features WiFi 6, offering faster speeds, lower latency, and better performance in crowded networks compared to WiFi 5. Bluetooth 5.2 ensures stable connections with wireless peripherals like keyboards, mice, headphones, and controllers. In addition, the mini PC includes a wide range of ports, including multiple USB 3.2 Gen 1 and Gen 2 ports, Ethernet, audio jack, HDMI, and DisplayPort, ensuring compatibility with most devices.
