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 9,5 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 400 Watt rating, this power supply is ideal for entry-level gaming systems and multimedia PCs. In addition to powerful 3,3 V and 5 V lines, which are particularly stable thanks to DC-DC technology, the two 12 V lines (22 and 18 A) can together handle 384 Watts. Multi-core CPUs, GPUs, or RAID setups will all be amply supplied - 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. Two 6+2-pin connectors are available for the graphics cards. Five SATA and two Molex connectors are present and these offer connectivity to an extensive range of peripherals. All cables are permanently connected to the power supply and are sleeved.
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.
