Chieftec SteelPower Series BDK-550FC 550W - PSU, 80 Plus Bronze

The Chieftec SteelPower BDK-550FC is a 550-watt power supply unit designed for ATX-compatible systems. It operates with an 80 PLUS Bronze certification, which specifies its efficiency in converting AC to DC power. The fully modular cabling system allows builders to connect only the necessary cables, simplifying cable management and potentially improving internal airflow. With a standard ATX form factor and a compact depth of 140mm, it maintains compatibility with a wide variety of computer cases, including those with more limited space.

Internally, the unit utilizes active Power Factor Correction (PFC) to maintain stable voltage regulation under varying loads. A comprehensive suite of six protection circuits, including over-voltage (OVP) and short-circuit protection (SCP), is integrated to safeguard connected hardware. Thermal management is handled by a single 120mm fan engineered for low-noise operation. This PSU also supports a silent mode, which reduces fan activity during periods of low power consumption to further minimize acoustic output.
