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 9.7 dB (A) is fully 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 0.15 watts. At 20, 50 and 100 percent utilization, the power supply achieves up to 88 percent efficiency, which is rewarded with an 80 PLUS Bronze certificate.

With 500 watts, this system power adapter is ideal for entry-level gaming systems and multimedia PCs. In addition to strong 3.3 V and 5 V lines, which are particularly stable thanks to the DC-DC technology, the two 12 V lines with 24 and 20 A, which together can handle a powerful 456 watts, are especially convincing. Multi-core CPU, Pixel Bollard or Raid system therefore meet no supply problem - the dream of every Systembuilders.
