Hardware Secrets Silver Award

Introduction

The German brand be quiet! released last month a new high-end power supply series, the Dark Power Pro 10, with models ranging from 550 W to 1,200 W. The 850 W model has the coveted 80 Plus Platinum certification, while all other models have the 80 Plus Gold certification. Let’s test the 850 W version and see if it is a good pick.

The 550 W, 650 W, and 750 W models are manufactured by FSP, while the 850 W, 1,000 W, and 1,200 W are manufactured by Seasonic.

The be quiet! Dark Power Pro 10 850 W is 7.3” (186 mm) deep, using a 135 mm fluid-dynamic bearing fan on its bottom (be quiet! BQT T13525-XF20, a.k.a. “Silent Wings P10”).

The reviewed power supply has a modular cabling system with 15 connectors: four for video card power cables, five for peripheral/SATA cables, one for the ATX12V/EPS12V cable, four for fan power cables, and one for the “overclocking” panel, which is used for selecting whether the power supply will use a multiple +12 V rail or a single +12 V rail configuration. Only the main motherboard cable is permanently connected to the power supply. This power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 21.6” (55 cm) long
  • One connector with two cables, one with two ATX12V connectors that together form an EPS12V connector, and one with an EPS12V connector, 26.8” (68 cm) long
  • One cable with one EPS12V connector, 26.8” (68 cm) long
  • One cable with one ATX12V connector, 26.8” (68 cm) long
  • Three connectors, each with two cables with one six/eight-pin connector for video cards, 23.6” (60 cm) long
  • One cable with one six-pin connector for video cards, 23.6” (60 cm) long (for use with motherboards that have this connector for extra current)
  • Two cables, each with three SATA power connectors, 23.6” (60 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with two SATA power connectors, 23.6” (60 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with one SATA power connector, 23.6” (60 cm) long
  • One cable with three SATA power connectors, two standard peripheral power connectors, and one floppy disk drive power connector, 23.6” (60 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with three standard peripheral power connectors, 23.6” (60 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with two standard peripheral power connectors and one floppy disk drive power connector, 23.6” (60 cm) to the first connector, 5.9” (15 cm) between connectors
  • Two cables, each with one standard peripheral power connector, 23.6” (60 cm) long
  • Four cables, each with one standard peripheral power connector and one standard three-pin fan power connector, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG, which is the minimum recommended gauge. The number of connectors available is impressive. It allows you to install, out of the box, three high-end video cards that require two auxiliary power connectors each. Another highlight of the cable configuration is the presence of cables with lots of connectors as well as cables with a single connector. This way, you can install only the cables you are going to actually use, preventing your computer from ending up with a lot of unused cables hanging inside. For example, if you have only one hard drive, you can install the cable that has only one SATA power connector. On competing products, you would have to use a cable where two or three connectors would be left unused, occupying space inside the case.

Another highlight of the Dark Power Pro 10 850 W is the presence of four cables for powering fans. This way, you can have at least some of the fans available on your case controlled by the temperature sensor available inside the power supply.

The reviewed power supply comes with a switch for you to select your favorite configuration for the +12 V output: single-rail (with the switch turned on) or multiple-rail (the default configuration). The unit also comes with a jumper in case you want to “permanently” configure the unit as single-rail but don’t want to install the switch.
