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
Next, the B5 power supplies feature one of the most important standards for reliability - Japanese capacitors. Featuring a Japanese main capacitor on the 650W and 550W models, the B5 power supplies will provide 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 80PLUS Bronze requirements. Moreover, the B5 power supplies are designed with modern standards, including ATX V2.52, for performance and stability.
