Frequently Bought Together
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 an increased lifespan. Even more impressive, these power supplies continue to get shorter compared to its predecessors. Backed by EVGA's 5 Year Global Warranty, the EVGA B3 lineup will give you peace of mind for years to come.

Join the evolution of the Bronze age.
No, it's not magic. Despite adding more features and increased performance, the EVGA B3 lineup is shorter than most of its competitors. At only 150mm long (450B3, 550B3, 650B3) and 160mm long (750B3, 850B3), you'll notice the extra space in your case, but you won't miss any performance or functionality.

The EVGA B3 power supplies feature a Long Life Sleeve Bearing Fan, resulting in a quieter operation and a longer lifespan. Alternatively, flip on the EVGA ECO mode for fully silent operation at low to medium loads.

Featuring Japanese capacitors on the mainboard, 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 88% efficiency!

Use only the cables you need, reducing cable clutter and improving case airflow. Available on all B3 models.

EVGA ECO mode means the power supply is completely silent during low to medium loads. This is one quiet power supply!

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

550W EVGA 550 B3, Full Modular, 80 PLUS Bronze, SLI/CrossFire, Single Rail, 45.8A, 130mm Fan, ATX PSU is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Good for the price Only been running this for a week or so and not had any problems. What you really need to know is how long does it last and what problems did I have in the long term but obviously I can't say. Bought to power a Ryzen based system but had to put my old system back in the case until a replacement Mobo arrives, it runs my old AMD system fine. One of my main reasons for choosing this PSU was the 'ECO' feature that allows the fan to be off when supplying moderate loads as a silent system is crucial to me. I discovered that the fan does kick in when the PSU gets warm though and it is quite a powerful fan that moves a lot of air so it is quite loud when that happens.
