Silent computing specialist, Be Quiet! Has just announced the release of a new line of power supply units, known as the Straight Power E9 series, which was designed in order to deliver quiet operation at an affordable price point.

The new PSU series includes four models with a power output ranging from 400 to 700 Watts and delivering between two and four 12V rails with a rating of 18A.

Depending on the Wattage of the PSUs, the Straight Power E9 models can be certified for running CrossFireX or SLI setups, and the top of the line 700W even comes with four PCI Express power connectors, two eight pins and two six pin.

The main advantage that the Straight Power E9 series holds over its competitors however is the quiet operation achieved by these PSUs as they were tweaked in order to provide noise-free operation.

In order to achieve this goal, Be Quiet! used 135mm SilentWings fans with fluid dynamic bearing when designing the PSUs, which were paired together with the company's low noise fan grills and anti-vibration mountings.

In addition, the Straight Power E9 power supply units are also compliant with a wide selection of safety standards and feature 80PLUS Gold certification.

“Our Straight Power E9 line up is a worthy successor to its best selling predecessor,” said Oleg Ushkats, the director of the product development team.

“Our design team worked diligently to improve the critical areas of PSU functionality: silence, stability and efficiency. We are proud to offer this much quality and performance with a five year warranty,” concluded the company's rep.

The regular version of the PSU, featuring fixed cables, comes in five models with ratings of 400, 450, 500, 600 and 700 Watts, while the cable management version of the Straight Power E9 models range from 480 to 680 Watts.

Estimated prices (including VAT) start at 79,90€ ($109 US) for the 400W version and range up to 139,90€ ($191 US) for the 680W version with cable management.
