EVGA 550 B5 550W ATX Fully Modular Power Supply by EVGA

FULLY MODULAR SMALL-SIZE
The B5 power supplies provide maximum flexibility for system builders with a fully modular design and a small chassis across all models. At 150mm length, the B5 power supplies provide solid, affordable power for all manner of system builds and cases.

SAFE & RELIABLE JAPANESE CAPACITORS
Next, the B5 power supplies feature one of the most important standards for reliability - Japanese capacitors. Featuring 100% Japanese capacitors on the 850W and 750W models, the B5 power supplies will provide a safe and reliable power for years to come.

SILENT, LONG-LASTING 135MM FLUID-DYNAMIC BEARING FAN WITH ECO MODE
The ultra-quiet 135mm Fluid-Dynamic Bearing fan becomes silent when coupled with EVGA ECO mode to turn off the fan in low to medium loads. The larger fan and carefully tuned profile creates a quieter experience than the B3 power supplies.

EFFICIENCY AND REGULATION DESIGNED FOR THE MODERN PC
Featuring an LLC Resonant design + DC to DC converter, EVGA B5 power supplies are up to 89% efficient - well above 80 Plus Bronze requirements. Moreover, the B5 power supplies are designed with modern standards, including ATX V2.52, for performance and stability.
