CHIEFTEC Polaris Series PPS-550FC 550W - PSU, 80 Plus Gold

The CHIEFTEC Polaris PPS-550FC is a fully modular ATX power supply designed for efficient power delivery in modern PC builds. It operates with an 80 PLUS Gold certification, which corresponds to high energy efficiency under typical system loads. The internal design uses an LLC half-bridge converter with DC-to-DC technology to maintain stable voltage regulation for connected components. Its fully modular cabling allows builders to use only the required cables, which can simplify installation and support unobstructed airflow within the chassis.

This unit is built into a compact 140mm deep housing, ensuring compatibility with a wide range of standard ATX cases. System cooling is handled by a 120mm fan that features automatic speed control to balance thermal performance with acoustic output. The primary power cables measure 650mm in length, providing ample reach for cable management in larger enclosures. A comprehensive set of electrical protection circuits is integrated to safeguard the system and its components against power anomalies like over-voltage or short circuits.
