I am satisfied with the power supply of "be quiet", although the no-name predecessor was erwas quieter. Unfortunately, the old man was too weak after upgrading my PC. In the media market, I've bought and then installed a device of a renowned manufacturer. A big disappointment, because that part was loud as a hair dryer and was just as quickly hot. It was not even an application. So money back from the Internet, compare Peise and order. The "Be Quiet! Pure Power 530W" is quiet and there is virtually no voltage saddle depressions at an energy efficiency of almost 90% !!!. Since one has to wait until a value changes after the decimal point for a few ms in the BIOS. The connectivity options are absolutely ausreichreichend. Incl. two 8-pin PCI-E connectors, essential for good graphics cards. Cable ties are also included. In its category, this power supply is all in all a "round", recommended thing and the value for money is true!
