Design and Build
The KAMRUI Pinova P1 adopts a compact, square design typical of modern mini PCs, with dimensions of just over five inches square and two inches tall. This small footprint allows it to be placed almost anywhere on a desk, mounted behind a monitor using the included VESA mount, or tucked away in an entertainment center. The unit is finished in black, contributing to a professional and unobtrusive aesthetic suitable for office environments. The build is designed for 24/7 operation, having passed manufacturer stability tests, which suggests a focus on reliability for continuous use cases like digital signage or home servers.
The chassis accommodates a comprehensive array of ports on the front and rear, minimizing cable clutter. A quiet, efficient cooling fan is integrated to manage thermals, even under sustained load, which is crucial for maintaining performance and longevity in a small enclosure. The overall design philosophy prioritizes functionality and space efficiency, making it a practical choice where desk real estate is limited.

Performance and Features
Processor and Graphics Performance
At the heart of this mini PC is the AMD Ryzen 4300U processor, a quad-core chip with a base clock of 2.7 GHz and a boost up to 3.7 GHz. According to manufacturer data, this processor offers a performance advantage over comparable entry-level options, with cited improvements over specific Intel and older AMD models. This translates to capable handling of everyday computing tasks, including office applications, web browsing with multiple tabs, and multimedia streaming. The integrated AMD Radeon Graphics, with a frequency up to 1.4 GHz, provides basic graphical capabilities. It is sufficient for driving multiple 4K displays and handling light graphical workloads but is not intended for demanding gaming or professional video editing.
Memory, Storage, and Expansion
The system ships with 16GB of DDR4 RAM configured in a single-channel setup. A significant feature is its upgradeability; it supports dual-channel DDR4-3200 memory and can be expanded up to 64GB using two 32GB modules, which can dramatically improve system fluidity during heavier multitasking. Storage is provided by a 256GB M.2 SSD, which offers fast boot and load times. For expansion, the mini PC includes two M.2 2280 slots: one PCIe 3.0 x4 NVMe slot and one slot that supports either SATA or NVMe PCIe 3.0 x2. The total SSD expansion capacity is listed as up to 4TB, making it suitable for users with large media libraries or those needing a compact network-attached storage (NAS) solution.
Connectivity and Ports
Connectivity is a strong suit for the Pinova P1. It supports triple 4K display output simultaneously through its HDMI 2.0, DisplayPort 1.4, and USB-C (with DisplayPort Alt Mode) ports. This multi-monitor capability is a standout feature for productivity, financial trading, or creative workflows. For peripherals, it offers six USB 3.2 ports and one USB-C port for data, reducing the need for external hubs. Network connectivity is covered by dual-band Wi-Fi 5 (802.11ac) and a Gigabit Ethernet port, providing options for stable wired or wireless connections. Additional features include a 3.5mm audio jack, Wake-on-LAN, Auto Power-On, and RTC Wake, enhancing its utility for remote management and always-on applications.
Setup, Support and Ownership
Setup is straightforward, with the package including the mini PC, a power adapter, an HDMI cable, and a VESA mount with screws. The operating system is pre-installed, allowing users to begin configuration quickly. The upgrade process for RAM and storage is user-accessible, a key benefit for tech-savvy owners looking to extend the system’s lifespan or tailor it to specific needs. The manufacturer does not list detailed support policies or software update schedules. However, the inclusion of TPM 2.0 is a positive note for security-conscious users and businesses, as it enables features like drive encryption. For those considering this PC for specific uses like home theater, exploring other compact media center options can be worthwhile.

The KAMRUI Pinova P1 Mini PC successfully delivers on the core promise of its category: capable computing in a very small package. Its standout feature is unequivocally the triple 4K display support, which is rare at this price point and opens up significant productivity potential. The thoughtful port selection, upgrade-friendly design, and focus on quiet, reliable operation make it a pragmatic choice for a wide range of standard computing scenarios. While it makes some compromises, such as the base single-channel RAM and older Wi-Fi standard, these are understandable trade-offs that keep the system accessible.
Ultimately, this is a device that excels as a dedicated tool for specific environments—be it a multi-monitor trading desk, a compact home office corner, or a living room media hub. It offers a solid foundation that users can upgrade over time. For anyone needing a general-purpose desktop that disappears into their workspace and handles day-to-day tasks with competence, the KAMRUI Pinova P1 is a compelling option that balances features, performance, and form factor effectively.
FAQs
Can the KAMRUI Pinova P1 run games?
The mini PC is not designed for gaming. It uses integrated AMD Radeon Graphics, which are suitable for basic display output, video playback, and very light or older games. Modern, graphics-intensive AAA titles will not run well, if at all. It is best considered for productivity, media consumption, and general computing tasks.
How many monitors can it support at once?
It supports three monitors simultaneously at up to 4K resolution each. You can connect one monitor via the HDMI 2.0 port, a second via the DisplayPort 1.4, and a third using the USB-C port, which carries a DisplayPort 1.4 signal. This makes it an excellent choice for multi-tasking and professional workflows that benefit from extensive screen real estate.
Is it easy to upgrade the RAM and storage?
Yes, the system is designed with upgradeability in mind. It has two slots for DDR4 RAM, supporting up to 64GB total in a dual-channel configuration. For storage, it has two M.2 2280 slots, allowing you to add a second SSD or replace the existing one. The total SSD capacity can be expanded up to 4TB, offering plenty of room for growth.
What operating system does it come with?
The specifications list the operating system as “OS Pro,” which typically indicates a version of Windows 11 Pro. This includes features beneficial for business use, such as enhanced security and remote desktop capabilities. The system should be ready to use out of the box with the OS pre-installed.
