Flex ATX form factor (hereinafter referred to as Flex) is a power size designed for small industrial control computers. 150*81.5*40mm, some users call it small 1U. It is currently widely installed in network switches, firewalls, and related products.

A2: Since the usage environment of industrial computers are different from the environment of general home/office computers, therefore, the power’s: 
1. Working temperature is 0~50 degrees Celsius
2. They operate 24-hours a day without interruption, therefore, the cooling fan needs to operate for long periods of times, so ball-bearing fans must be used

After eliminating the A2 problem, it seems that it can in the short-run. However, the life cycle of the IPC system vendor’s products must be at least 5 to 10 years, and the life cycle of the retail market powers is only two to three years and cannot satisfy the logistical requirements of IPC SE; therefore, it is not suitable.

CRPS is short for Common Redundant Power Supply; it is a power module specification applied in the server field defined by Intel together with many leading companies in the industry. The specification focuses on the demands for digitalization, high efficiency, high density, compact size and high stability; it is agreed by many system vendors and widely adopted in the industry.

Although CRPS is a shared specification, the different companies may have different applications and designs in terms of detail; therefore, it cannot be used together with CRPS power products from other companies.

 FSP has complete plans for this; please refer to this.

You must choose a product compliant with the latest ATX 3.0/3.1 standards. FSP offers industrial power supplies compliant with ATX 3.0/3.1, featuring native 12VHPWR (or 12V-2x6) connectors. This allows FSP PSUs to handle extreme Power Excursions up to 200%, flawlessly supporting next-generation PCIe Gen 5 GPUs from NVIDIA and AI accelerators, guaranteeing rock-solid stability for AI computing systems.

The key is utilizing power modules with redundancy features. FSP's CRPS series provides N+1 redundant designs and supports hot-swappable functionality. Even if one module fails, the system continues to operate normally, and maintenance can be performed without downtime—providing the ultimate safeguard for Mission-critical applications.

Edge Computing is frequently deployed in non-climate-controlled environments, demanding robust power resilience. FSP's industrial-grade PSUs are engineered for severe conditions, guaranteeing non-derated full-load output at 50°C ambient temperatures and normal operation at altitudes up to 5,000 meters. Furthermore, FSP products are ruggedized against high humidity and dust, securing the long-term reliability of outdoor edge devices.

This requires selecting a PSU that supports digital communication protocols. FSP's entire lineup of PS2 Redundant and CRPS power supplies supports the PMBus 1.2 protocol. System administrators can monitor real-time voltage, current, temperature, and fan speeds via PMBus, enabling predictive maintenance and intelligent energy management—especially ideal for unmanned server rooms or remote sites.

Driving high wattage within minimal volume is the networking industry trend. FSP provides a comprehensive range of Flex ATX and 1U Redundant power supplies boasting exceptional power density. Explicitly designed for firewalls, routers, and rackmount servers, these products deliver highly stable power within confined spaces, complemented by low noise profiles and easy cable management.

With the convergence of ICT technologies, next-gen safety standards are mandatory. FSP's entire line of IPC power supplies is certified to the latest IEC 62368-1 standard. This standard replaces the legacy IEC 60950, comprehensively covering safety regulations for Information Technology (IT) and Audio/Visual (AV) equipment, ensuring your end products can be smoothly marketed globally.

Elevating power conversion efficiency is the most direct energy-saving method. FSP provides industrial power supplies certified 80 PLUS® Platinum and Titanium, delivering conversion efficiencies up to 96%. This drastically minimizes waste heat generated during power conversion, offloading cooling systems, and significantly improves the data center's PUE (Power Usage Effectiveness), helping you hit energy conservation and carbon reduction targets.
