NEXUS has just announced the ultra-quiet NX-8060 600W modular power supply:
The Nexus 80-plus series power supplies are guaranteed to provide you with over 80% efficiency. This means the power supply is using the power it is drawing from the wall outlet more efficient and less electricity is wasted. Obviously this is better for the environment and it saves you on your electricity bill! A more efficient power supply also results in a cooler power supply. So less cooling is needed and we are able to make the power supply even quieter.
By carefully selecting each and every component we aim at creating the best possible mix of components to make our power supplies as silent as possible. We carefully balance performance and noise level to get the best of both worlds. We are confident that our power supplies are leading the market when it comes to solid performance at the lowest possible noise level. From our noise level tests we know the Nexus NX-8050 produces only 17,5 dB(A)* in idle mode measured in a chamber with 15.5 dB(A) background noise. See graph below.
