Introducing the EVGA 550 B5 power supply unit, the latest 80PLUS Certified Bronze power supplies to carry on the EVGA tradition of reliability, performance, and affordability. The EVGA 550 B5 PSU starts with the most important standard for reliability—a Japanese main capacitor. Next, the EVGA 550 B5 provides maximum flexibility using a small chassis and a fully modular design. The ultra-quiet 135mm Fluid-Dynamic Bearing fan becomes silent when coupled with EVGA ECO mode to turn off the fan in medium to low loads.
