The response to our recent Silent Power Supply Special was very high and a flood of positive emails we received from the audience, of course, not too stingy with wishes regarding further test candidates. In particular, the vaunted Zalman NT with early praise was the object of desire please understand that we can not fulfill every request, test, especially if there is a corresponding non-silent as a model to be classified.


However, this was usually because some readers have misunderstood the hanger to the test well main focus was primarily the noise and no mod-specific adaptations whether a corresponding NTs Spannungspoti - with which the stresses can be further adjusted, and how - was not the subject of our tests.

Who expects me to buy a silent power supply, and I've seen a whole then a silent system, will be disappointed once started with noise optimization, the user will notice that the CPU cooler brothers next, then the case fans, the fans of the peripherals, etc the addiction to further optimization is inevitable inevitable, something is a still too loud.


Unlike other test magazines, we make no metrological laboratory tests power supply and measure the so-called full load, therefore, not by external loads. We measure in the user understandable, practical realities with Prime95 and over a period of at least one hour in multiple passes - usually three times for each candidate the idle mode is measured after 1 hour rest period.


We have determined that a particular power supply for AMD-based systems on the 3.3 and 5V line ideally should have a total of around 180-200W thus, the user is currently well supplied and should have a stable power supply under all circumstances in dual systems, it may also be a little more quiet. With a Pentium 4 system, however, the performance of the 12 volt line crucial for stable operation, especially since they make use of the 12V line and refer the Intel processors from their retirement benefits with at least 180 watts on this line but it is on the safe side.
