Introducing the New EVGA B3 80+ Bronze Power Supplies
Join the Evolution of the Bronze Age
EVGA Bronze power supplies have become synonymous with industry-leading stability, performance, and value.
With the B3 power supplies, EVGA now adds fully modular cables, the ECO Intelligent Thermal Control System, even tighter voltage regulation (<2%), and a Long Life Sleeve Bearing Fan for ultra-quiet performance with increased lifespan.
Even more impressive, these power supplies continue to get shorter compared to its predecessors.
Big Package, Small Size
No, it's not magic. Despite adding more features and increased performance, the EVGA BS lineup is shorter than most of its competitors. Only 150mm long, you'll notice the extra space in your case, but you won't miss any performance or functionality.
5 Year EVGA Warranty
Backed by EVGA's Rock Solid 5 Year Global Warranty, EVGA's B3 Power Supplies are designed to be rugged and keep working, so they are designed to give you peace of mind for years to come.
Silence Doesn’t Have To Be Golden
The EVGA B3 power supplies feature a Long Life Sleeve Bearing Fan, resulting in quieter operation and a longer lifespan. Alternatively, flip on the EVGA ECO mode for fully silent operation at low to medium loads.
Next Gen Performance
Featuring models with a mainboard Japanese Capacitor, the B3 lineup takes the already efficient B2 series and makes it even better with near-Silver efficiency and tighter voltage regulation (<2%). These power supplies have up to 85% efficiency at 120Vac!
Fully Modular Design
Use only the cables you need, reducing cable clutter while improving case airflow.
