In May, be quiet! released the first three units in the Dark Power Pro 11 lineup. At the time, customers were given the choice between three high capacity power supplies; 850 W, 1000 W and 1200 W units were available. Now, the company has extended that line to include more affordable 550 W, 650 W and 750 W options for less demanding builds.
Dark Power Pro 11 power supplies in all capacities, from 550 W to 1200 W, offer a semi-modular design to help with cable management, and the housing is equipped with rubber linings to reduce vibration in the case.
Each unit makes use of a temperature-controlled fan connector to help reduce noise. be quiet! equipped the Dark Power Pro series of power supplies with a 135 mm SilentWings 3 fan, which the company said enables near-silent operation. The fans make use of a 6-pole motor and fluid dynamic bearings, enabling a low startup speed of 220 rotations per minute. This should prevent the fans from making noise when first starting up.
The entire lineup of Dark Power Pro 11 power supplies carries 80-Plus Platinum ratings, and the company said they operate at up to 94 percent efficiency. be quiet! has chosen to use Japanese electrolytic capacitors for durability and reliability. They are designed to withstand temperatures as high as 105 degrees, and the company is so confident in the construction that it offers a 5-year warranty on all Dark Power Pro 11 power supplies.
be quiet! said the trio of new power supplies is available now. The 550 W model will set you back $149, the 650 W is available for $164, and $175 will get you into a 750 W unit.
