With further innovations in detail is be quiet! again before the Pro 11 power supplies an excellent successor to the multi award-winning Dark Power Series. Instead of 80 Plus Gold now surpass all power levels 80 Plus Platinum and achieve up to 94 percent efficiency. Apart from the basic structure remains largely intact - including the quiet Silent Wings fan (now, however, in the version of Silent Wings 3 with sechspoligem engine), the innovative overclocking Key and handy cable management.

In addition, the power supply is once again very classy and at the same time designed extravagant. For an eye-catching case makes especially the fan grille. But even the sedentary among 135 SilentWings 3 exhaust convinces with its unusual and unique, streamlined rotor design and high quality encapsulated FDB liquid storage. He has a wide range of electronic and mechanical improvements for the best possible balance between optimal cooling effect and a quiet operation. In combination with the revised speed profile the Dark Power 11 therefore operates even quieter than the popular at Silent friends predecessor.

In order to achieve the maximum efficiency of fabulous 94 per cent, only first-class electronics is used - among other things, a modern DC-DC module and enormously high 105 ° -certified Japanese capacitors. The reactive power correction (PFC) is also almost perfect with 99 percent. But even in stand-by, the power supply is enormously strong and consumes less than 0.10 watts.

550 watts, this version of the Dark Power Pro 11 as a continuous output available - high-end technology for the middle watt class. The 12-V line provides thereby a combined current of 45 amps at enormous a total output of 540 watts and is fourfold split, the individual lines each provide 20 to 25 amperes. By default, therefore, is at P11 to a multi-rail power supply.

An unprecedented amenities feature represents the so-called overclocking Key. This is a switch that allows it to operate the power supply on request as a single-rail power supply. Depending on the position the 12 V cable is either quadruple split or operated as a single, strong line. The switch is located here on a PCI aperture and can be installed into a free slot. A handle to the rear panel and the mode is changed.

The advantage: Bifurcated 12V rails offer higher operational reliability, are individually but only limited loads. Sucks now a single component as one of the split lines allows for more - which can easily happen when extreme overclocking - then disables the power supply. With a single, interconnected 12-volt line, the load limit is however only achieved with the maximum power of the combined 12 V power.

Also the connection Arsenal leaves nothing to be desired and has a modular design, as with all Dark-power models. Here only the 20 + 4-pin motherboard connector is hardwired. All other terminals are removable, which guarantees maximum flexibility and minimal clutter. For the graphics cards are a total of five PCIe connector willing of which have a 6-pin and four 6 + 2 pins. Likewise spendabel the periphery with eight SATA, five 4-pin Molex and one floppy is considered.

A very practical solution also represent four separate connectors for case fans. The connected fans are automatically controlled by the power supply, which depending on load optimal cooling is available and at the same time a minimum noise level is guaranteed. So an additional fan controller or voltage throttling is no longer necessary - unless they are to be influenced.

Also noteworthy is the free on-site exchange (within Germany and France) in the first year. Within 48 hours, the power supply in the case of a defect therefore changed directly at your home. Longer waiting times by shipping, manufacturer inspection etc. are a thing of the past.
