Antec CSK550DC 550W 80 Plus Bronze Power Supply Unit
The Antec CSK550DC is a high-quality, cost-effective 550 W power supply unit designed for mainstream and gaming PC builds. With up to 88% efficiency and 80 Plus Bronze certification, it delivers stable, reliable power while helping to reduce energy waste.
A DC-to-DC architecture and active Power Factor Correction (PFC) ensure consistent performance, while Antec’s CircuitShield protection suite provides comprehensive safety. A quiet 120 mm temperature-controlled fan and flat black non-modular cables help maintain clean builds with efficient airflow. Reinforced PCI-E 5.1 connectors support modern GPUs, and the compact ATX design (140 x 150 x 86 mm) fits easily into a wide range of compatible cases. Antec backs the CSK550DC with a 5-year manufacturer warranty.
