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. |
