With an outstanding price/performance ratio, excellent efficiency and high-quality workmanship, these compact power supplies are directed primarily towards system integrators and price-conscious system builders.

The be quiet! System Power 9 at a Glance:

  • Fantastic price/performance ratio
  • Stable power supply thanks to DC-DC technology
  • 4x 6+2-Pin connectors for multi-GPU systems
  • Quiet, high-quality, temperature controlled 120 mm fan

The be quiet! System Power 9 in Detail:

The discreetly designed System Power series of power supplies have a low installation depth of just 14 cm, which makes them compatible with older and smaller cases. Cooling is provided by a 120 mm fan with automatic speed adjustment. The power supply unit produces just 10,6 dB(A) at around 20% load, which is exceptionally quiet.

Thanks to numerous energy-saving and efficiency-enhancing measures, electricity consumption and heat generation are both very low. Even the standby consumption is low at an incredible 0,15 Watts. At loads of 20, 50 and 100% the power supply achieves an efficiency of up to 89% to earn an 80Plus certification.

With a 700 Watt rating, this power supply is a powerful entrant to the System Power 9 series, capable of producing more than enough power for many different scenarios. In addition to powerful 3,3 V- and 5V rails, which are especially stable thanks to DC-DC technology, it is the two 12 V rails rated at 33 and 25 A which are truly impressive due to their ability to output 672 Watts. Multi-core CPUs, GPUs or RAID setups will all be powered flawlessly - perfect for any system builder.

A broad range of connections are available on this power supply. A 20+4-pin- and a 4+4-pin ATX connector supply power to the motherboard. Four 6+2-pin connectors are provided for the graphics cards. Six SATA- and two Molex connectors enable an extensive range of peripherals to be connected. All cables come sleeved and attached to the power supply.

Be quiet! has also provided a long 3 year warranty period for their power supplies as well as a range of important protections e.g. over- and undervoltage, overcurrent, short-circuit protection, overheating and overload protection.
