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.
