Introducing the EVGA B5 power supplies, the latest 80PLUS Certified Bronze power supplies to carry on the EVGA tradition of reliability, performance, and affordability. The B5 power supplies start with the most important standard for reliability - 100% Japanese Capacitors. Next, the B5 power supplies provide maximum flexibility by 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. Last, but not least, the B5 power supplies have a full suite of protections and a 5-year limited warranty that you've come to know and expect from EVGA.
