Superflower 550W Zillion Bronze Power Supply

ATX 3.1 Compatibility with 200% Power Excursion Support
Compliant with Intel’s ATX 3.1 standard, this PSU is capable of handling up to 200% power excursions, providing stable performance even during intense, sudden power demands. It includes HCS terminals and dual 8-pin sockets leading to a 12+4-pin GPU plug, preventing excessive cable bending for a safer, more reliable connection.

High-Efficiency 80 PLUS Gold Certification
Certified as 80 PLUS Gold, it achieves efficiencies of approximately 87 % at 20 %, 90 % at 50 %, and 87 % at full load (115 V source), ensuring strong energy savings and reduced heat generation.

Advanced Thermal & Fan Design
Equipped with a 140 mm Fluid-Dynamic-Bearing (FDB) fan featuring a distinctive 9-blade design and copper shaft, the PSU offers high airflow, accurate fan RPM control, quieter operation, and enhanced durability. It also supports an ECO (semi-fanless) mode to reduce noise when idle.

Fully Modular with Modern Cable Design
The fully modular design uses flexible ribbon-style cables, enhancing cable management and airflow. Additionally, it includes a revised, safer 12V-2×6 (12VHPWR) connector for compatibility with next-generation PCIe 5 graphics cards delivering up to 600 W.

Robust Componentry & Protection Suite
Built with top-tier Japanese capacitors for improved reliability and longevity, this PSU features a full array of protection mechanisms—including over-voltage, over-current, over-power, short-circuit, under-voltage, over-temperature, no-load, and surge/inrush protection—to safeguard both the unit and your system.
