The CHIEFTEC Polaris 3.0 PPS-1250FC-A3 is an ATX power supply that provides a total output of 1250 watts for high-demand computer systems. It is engineered to the ATX 3.0 standard and supports PCIe 5.0 connectivity, ensuring compatibility with contemporary high-performance components. The unit's design incorporates an LLC half-bridge converter with DC-to-DC technology to maintain stable power delivery and tight voltage regulation. Its 80 PLUS Gold certification signifies a high level of energy efficiency during operation.
This power supply features a fully modular cabling system, which permits the use of only the required cables to facilitate a cleaner build and improve internal airflow. Cooling is handled by a 135mm fan equipped with a fluid dynamic bearing (FDB) for increased longevity and lower operational noise. The internal construction uses Japanese main capacitors, a choice that contributes to the unit's reliability and consistent performance. The power supply's housing measures 160mm in depth, making it suitable for a wide range of standard ATX chassis.
