Fujitsu Esprimo Q558 USDT / Intel Core I5-9400T

Introduction to the Ultra-Small Form Factor (USDT) Ecosystem

The Fujitsu Esprimo Q558 represents the culmination of German engineering applied to high-density desktop computing. This device, categorized as USDT (Ultra-Small Form Factor), is not merely a small computer; it is a workstation optimized for the modern business life cycle. Equipped with the Intel Core i5-9400T processor, this unit balances the need for multi-core processing with exemplary thermal and energy management.

Intel Core i5-9400T Processor Architecture

The heart of this unit is the Intel Core i5-9400T, belonging to the ninth generation of the Coffee Lake Refresh architecture. Unlike the standard "S" or "K" versions, the "T" suffix indicates optimization for low energy consumption (35W TDP). This allows the Fujitsu Esprimo Q558 to maintain stable frequencies without generating excessive heat, which is critical in chassis under 2 liters in volume.

With 6 physical cores and 6 threads, multi-tasking performance far exceeds its four-core predecessors. Intel Turbo Boost 2.0 technology allows the processor to scale from a base frequency of 1.80 GHz up to 3.40 GHz, providing power on demand. The 9 MB Smart Cache ensures that data flow between RAM and the cores remains fluid and efficient.

RAM Capacities and Data Performance

To ensure a seamless user experience, the Fujitsu Esprimo Q558 incorporates two slots for SO-DIMM DDR4 modules. The maximum expansion capacity reaches 32 GB of RAM, operating at a speed of 2666 MHz. This configuration is vital for using virtual machines, editing massive spreadsheets, and simultaneously running multiple web browsers with dozens of active tabs.

The Dual Channel architecture allows for doubling the memory bandwidth, directly benefiting the integrated Intel UHD Graphics 630 GPU, as it uses part of the system memory for graphics and 4K video processing.

Solid State Storage and Internal Expansion

Storage is a fundamental pillar of perceived performance. The Q558 supports NVMe PCIe M.2 units, which offer read and write speeds up to 5 times faster than traditional SATA SSDs. Additionally, it features a 2.5-inch bay for SATA III units, allowing for hybrid configurations where the operating system resides on the M.2 and bulk data on a second SSD or HDD.

Data security is managed through the integrated TPM 2.0 (Trusted Platform Module) chip, which facilitates disk encryption via Windows BitLocker, ensuring corporate information is protected against unauthorized access in case of physical theft.

Video Connectivity and Multi-Monitor Configuration

In the realm of productivity, the ability to manage multiple screens is non-negotiable. The Fujitsu Esprimo Q558 comes standard with two DisplayPort ports, capable of outputting video signals in 4K resolution at 60Hz. Additionally, it includes a DVI-D port for compatibility with legacy monitors.

This triad of outputs allows for extended desktop configurations, increasing worker efficiency by avoiding constant window switching. The integration of Intel Quick Sync Video technology also guarantees hardware-accelerated video encoding and decoding, ideal for high-definition video conferencing without saturating the CPU.

Energy Efficiency and Environmental Sustainability

Fujitsu has designed this equipment under strict energy efficiency standards. The internal power supply is 80 PLUS Gold or Platinum certified, ensuring minimal energy loss as heat. Standby power consumption is extremely low, complying with Energy Star 7.0 regulations.

The Fujitsu Esprimo Q558 design minimizes plastic use and facilitates recycling. Furthermore, the Zero Noise Habit function allows the fan to stop completely during basic tasks, reducing office noise pollution and mechanical component wear.

Business Management and Hardware Security

For IT departments, manageability is key. The Intel H310 chipset provides a solid foundation for fleet management. While it does not include full vPro, the Q558 offers secure BIOS options, write protection, and the ability to disable individual USB ports to prevent data leakage.

The chassis includes a Kensington lock slot and optional intrusion sensors. Its small size allows for installation on VES
