NX-3000 Real Silent Power Supply 300Watt



This power supply has been designed to beat the best silent power supplies in the market today. The Nexus NX-3000 was tested in a Anechoic chamber using Brüel & Kjær testing equipment and compared with the leading existing quiet power supplies and came out a winner with an average of 5 dB(A) in favor of the NX-3000
