Build your PC with the EVGA B5 Series power supply, perfectly combining high efficiency, low noise level, solid reliability, and affordable price. Fully modular design reduces cable clutter and improves airflow, making your build look tidy and always stay cool.
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 Capacitor
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.
