The HP Pro Mini 400 G9 is a compact desktop computer designed for commercial use, distinguished by its small form factor and professional specifications. As a mini-PC, it delivers the performance of a full-featured workstation in a space-saving housing, making it ideal for integration into offices, retail environments, or small workspaces. The computer is equipped with an Intel® Core™ i5-14500T processor, featuring 14 cores (6 performance cores and 8 efficient cores) and supporting 20 threads. The maximum turbo frequency of the performance cores reaches 4.8 GHz, while the efficient cores can reach up to 3.4 GHz. The processor includes a 24-MB L3 cache and a base power consumption of 35 W, with a maximum turbo power of 92 W. This configuration enables balanced performance for office applications, multitasking, and light to moderate productivity tasks.

Applications

The HP Pro Mini 400 G9 is designed for small and medium-sized enterprises as well as established companies requiring a reliable, powerful, and secure IT infrastructure. Its compact design makes it particularly suitable for workspaces with limited space, such as retail counters, call centers, or medical practices. The robust construction, compliant with MIL-STD 810 and HP Total Test Process requirements, ensures high reliability and longevity under various operating conditions.

Features and Specifications in Detail

The computer features 16 GB of DDR5-SDRAM with a clock speed of 4800 MHz, installed as a single 16-GB module. Two DIMM slots allow for future expansion, with a maximum RAM capacity of 16 GB. As storage, a 256-GB SSD with PCI Express interface and NVMe support is integrated, providing fast boot and access times. The integrated graphics solution is based on Intel® UHD Graphics 770, sufficient for office applications, web browsing, and multimedia. An optical drive is not included.

Technology Explained Simply

The CPU of the HP Pro Mini 400 G9 uses the hybrid architecture of the Intel Core i5-14xxx series, where performance cores handle demanding tasks and efficient cores manage energy-optimized processes. The combination of 14 cores and 20 threads enables efficient parallel processing. The DDR5-SDRAM memory architecture offers higher bandwidth and lower latency compared to DDR4, resulting in faster system response and smoother multitasking. The NVMe SSD utilizes the PCIe interface to achieve maximum data transfer rates, which is particularly beneficial for operating system boot time and application loading speed.

Compatibility and Accessories

The mini-PC supports installation of Windows 11 Pro and comes pre-installed with a range of HP tools, including HP Notifications, HP Support Assistant, and HP PC Hardware Diagnostics. Network functions include a Gigabit Ethernet port (10/100/1000Base-T(X)) as well as Wi-Fi 6E (802.11ax) with an Intel Wi-Fi 6E AX211 controller and a 2x2 antenna configuration. Bluetooth 5.3 is also integrated. Connectivity options include two USB 3.2 Gen 1 (3.1 Gen 1) Type-A ports, three USB 3.2 Gen 2 (3.1 Gen 2) Type-A ports, one USB 3.2 Gen 2x2 Type-C port, two DisplayPort 1.4 ports, and one HDMI 2.1 port. A combined headphone/microphone jack is also available. The Flex ports allow for individual configuration with options such as HDMI, DisplayPort, VGA, serial ports, or Dual USB 2.0.

Installation and Mounting

The HP Pro Mini 400 G9 is designed as a mini-PC and can be placed on a desk or mounted on a wall. Installation is performed via standard PC installation under Windows 11 Pro. The power supply is rated at 90 W and operates with an input voltage of 100–240 V at 50/60 Hz.
