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.
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 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 less than 2% ripple. 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.

Pros: Well its a good price for something from EVGA. The second one worked great. Nice cabling, great paint job. After the RMA on the first unit. The RMA service is top notch. Shiped it out and it was a one day turnaround with UPS and three days I have a new PSU
Cons: First PSU died the first day. It had a problem. Second one was fine no cons
Overall Review: EVGA's RMA service is great. They try to sell you a "advanced RMA" to send you a unit before you send the old one in but its not necessary. The RMA service is so fast. I just called them and they were very helpful and 5 days later I had a new PSU
