The German power supply manufacturer Be Quiet! launched a new series of affordable 80Plus Bronze PSUs under the name Power Zone. We tested the 650W and 750W models.

Be Quiet! developed the new Power Zone line of products in order to provide customers with energy-efficient power supplies that are also affordable. The series has four different models: 650W, 750W, 850W and 1000W. They're all based on a design by FSP, who also manufactures the power supplies. Be Quiet! claims it has optimised the PSUs in a number of ways. They're 80Plus Bronze certified and should be up to 90 percent efficient according to the manufacturer.
