The CHIEFTEC Polaris 3.0 PPS-1050FC-A3 is a 1050W power supply unit compliant with the ATX 3.0 standard to support high-demand components. It is engineered to power PCIe Gen 5 hardware, making it suitable for modern computer builds with next-generation graphics cards. The unit has an 80 PLUS Gold certification, indicating a high level of efficiency in converting AC to DC power. Internally, it employs an LLC half-bridge converter and DC-to-DC technology to maintain tight voltage regulation and low ripple under various load conditions.
This power supply features a fully modular cabling system, which allows for the use of only necessary cables to facilitate cleaner system builds and potentially improve internal airflow. Thermal management is handled by a 135mm fan with a Fluid Dynamic Bearing (FDB), selected for its quiet operation and durability. The design incorporates Japanese main capacitors for enhanced reliability and consistent performance over time. It adheres to the standard ATX form factor with a depth of 160mm, ensuring compatibility with most mid-tower and full-tower cases.
