    Stand-by consumption of less than 0.13 watts
    All important protection functions available

That be quiet! System Power B9 in detail:

The discreetly designed System Power power supplies have a low installation depth of only 14 centimeters, which makes them compatible for older and smaller housings. Cooling is provided by a 120mm fan with automatic speed adjustment. Especially at low utilization of about 20 percent, the power supply with a noise level of only 11.6 dB (A) is completely silent-capable.

Thanks to numerous energy-saving and efficiency-enhancing measures, power consumption and heat generation are very low. Even the stand-by consumption is just incredible 0.13 watts. With a capacity of 20, 50 and 100 percent, the power supply achieves an efficiency of up to 87 percent, which is rewarded with an 80Plus certificate.

At 300 watts, this system power adapter is ideal for multimedia and office PCs. In addition to stable 3.3 V and 5 V lines, the two 12 V lines with 18 and 14 A, which together can handle 276 watts, are especially convincing. Modern multi-core CPUs and peripherals are therefore always supplied with sufficient energy.

For their power supply is a wide arsenal of connections available. A 20 + 4-pin and a 4-pin ATX plug supply the motherboard. Four SATA and two Molex ports supply the peripherals. All connection cables are firmly connected to the power supply.

Also noteworthy is the very long manufacturer's warranty period of 3 years and the presence of all important protection functions, such as overvoltage and undervoltage protection, overcurrent protection, short-circuit protection, overheating protection and overload protection.
