I've got the power ...

Listan last month released their updated versions of the Be Quiet! Dark Power Pro, namely the First Class edition of power supplies. The engineers at Be Quiet! have enhanced the new Dark Power PRO models in terms of technology and efficiency. The efficiency rate according to Listan, is now up to 88%, (85% on average load).

The advantages of the new First Class PSU's can be summed up in the following three basic ideas:

• The new Dark Power Pro models include ECASO technology, high efficiency rate (88%), the number of 12v circuits and the silent operation of the PSU fan. ECASO technology controls the speed of the PSU fan and up to a maximum of 4 additional casing fans, according to temperature.
• With First Class Connectivity. The power supplies are fitted with at least 16 cable sets, of which up to 14 are removable. The units also have 2 PCIe 6+2-pin connectors for SLI and Crossfire graphic card systems. A special feature of the new Dark Power Pro models is a non-interchangeable, intelligent connection concept. There is a special colour coding system on the power supply connections and also on one side of the modular power cables that prevents any mix-up of the cable directions. For a tidier PC, an all-in-one cable is supplied, enabling two Molex, two SATA connectors and a floppy drive to be grouped together in a single bundle.
• First Class Service is what customers can expect after purchasing a Be Quiet! power supply or in the event of any claims under warranty. Be Quiet! offers a full 3-year warranty (1 year more than the legal requirement), and in several EU countries a convenient on-site replacement service during the first year. The service will provide a replacement straight to your door within 48 hours.

Listan released this power supply with the statement it will not only have a huge amount of power across all rails, but does so with very little noise. Furthermore you'll notice that the 650 Watt First Class edition has terrific aesthetics which we'll show you later on and likely is the most user-friendly PSU we ever tested.

The PSU comes with advanced cable management. e.g. modable cables. You install the cables that you need, and that's it. Supplied are 18 connectors of the majority is detachable. For SLi and Crossfire you can go up-to two graphics cards with the cables supplied. The PCIe cables are PCIe 2.0 compliant, meaning you'll also can connect the new 8-pin (6+2-pin) header that can carry 150 Watts per cable. We'll show you in the photo shoot.

Here's a brief sum on cable management:

• 1x 24 Pin Motherboard Connector with Adaptor to 20 Pin
• 1x RPM control (3pin)
• 1 x cable for peripherals 600+150+150+150+150mm( 2xSATA / 2xHDD / 1xFDD )
• 1 x cable for peripherals 600+150+150+150mm ( 4 x HDD )
• 1 x cable for SATA connector 600mm+100+100+100(4 x SATA) include 3.3V
• 2 x cable for PCIe connector 600mm with 8pin to 6+2pin
• 1 x cable for P8 connector ( 8 pins ) 600mm
• 1 x cable for P4 connector ( 4pin ) 600mm
• 1 x cable for Motherboard ( Molex 4pin ) 600mm
• 1 x cable for mainboard ( Dualboard ) EPS 6pin 600mm
• 4 x cable for case fans ( controlled by PSU ) 700mm ( 1 x Molex / 1 x 3pin )
• 1 x cable for peripherals 500mm ( 1x HDD)
• 2 x cable for SATA 500mm ( 1 x SATA )

Power distribution wise we notice a quad 12V rail with plenty of voltage available to serve high-end needs.

• +3,3V: 26A
• +5V: 30A,
• +12V1: 20A, +12V2: 20A, +12V3: 20A, +12V4: 20A
• -12V: 0,8A
• +5VSB: 4A (peak 5A)

Mind you that the combined output on the 12V rails has a load maximum of 52 AMPs. Considering that a GeForce Ultra consumes 10 A per card, you can do the math. It should be plenty even for a high-end SLI gaming system.

So there you have it, 650 Watts ready for dual GFX solutions and multi-core (server) systems.
