NX-4000 Real Silent Power Supply 400Watt



After setting the new standard for quiet 300 Watt power supplies we started to develop a real silent 400 Watt power supply. We set very high standards when it comes to quality, performance, power and silence. The Nexus NX-4000 Real Silent Power Supply is a true 400 Watt power supply and is again setting new standards! The NX-4000 is fitted with a wire grill and a premium quality fan. The NX-4000 produces only 21.7 dB(A) in idle mode!

Your PC is in need of more power than average? But you do want your computer to be as quiet as possible? The Nexus NX-4000 will not let you down!

Satisfaction Guaranteed!
