INTRODUCING THE EVGA B3 POWER SUPPLIES

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.

BIG PACKAGE, SMALL SIZE

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.

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 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!

FULLY MODULAR DESIGN

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

Does NOT have the extra 4 pin ATX plug required by higher end motherboards. 7/27/2019 7:56:31 AM

Pros: It is a nice looking fully modular power supply

Cons: Missing the required power connections needed nowadays

Overall Review: Does NOT have the extra 4 pin ATX plug required by higher end motherboards. I just tried to use this power supply with an AsRock X470 Taichi and the power supply does not have all of the required output plugs to work.

Works great, no issues 7/11/2019 11:36:31 AM

Pros: - EVGA packaging standards...
- Doesn't get hot during normal non-stressful use, so the fan stays off most of the time when on ECO mode, and when not in ECO mode, the fan spin noise is still non-existent
- Nice clean look
- Decent price, especially when on sale
- Japanese capacitors where it matters

Cons: - Can't think of any

Well made and still affordable unit 2/8/2019 3:02:02 PM

Pros: -Far more wattage than I need
-Nice modular connections
-Mounting screws included
-Decent efficiency rating
-ECO Mode extends fan life
-Silent- I haven't heard the fan turn on yet
-5 year warranty
-Looks good in basically any build

Cons: -Does not include the power on self-tester plug that some higher end EVGA units come packaged with. I really don't mind at all that it's not there, but I don't have anything else to write in the 'cons' section.

Overall Review: I highly recommend this for a lower budget PC build or simple power supply replacement. It's really easy to use and well built for its price point. I would never use a bargain bin power supply. This is about the best value you can find for a well made modular power supply for a machine that doens't need crazy amounts of power. It'll run pretty much any average machine and even some higher performance ones without issue.

Good stuff 1/12/2019 1:28:36 PM

Pros: - I don't hear it

- Plenty of power

Cons: - Cables a bit rigid but quality ones

- As usual with PSU, CPU cable too short ( I already ordered an extension )

Overall Review: Kind of like it.

Update ( January 12, 2019 ): I just bought a MSI RX 570 GPU and coil whining is almost imperceptible. Like it even more now.
