Quiet Power Supplies - NX-4090 Nexus 400 Watt 16.2 db Quiet Power Supply with 12cm fan

Nexus NX-4090 Quiet Power Supply

Nexus has done it again with this truly silent, 400 watt, quiet power supply with 12 cm fan. This NX-4090 is the most amazingly quiet power supply we've ever tested or sold! Not only is it impossible to hear, but with a bottom-mounted 120mm fan (power supply is shown upside down in picture to show you the fan) with wire grill, and a tranparent back full grid, it moves more air through your case than any truly quiet power supply on the market! Because of its incredible airflow and high wattage, this quiet power supply is well-suited for today's 3 Ghz and above quiet pcs.

NX-4090

The NX-4090 quiet power supply, designed by NexusTek, is the latest in innovation and efficiency. The NX-4090 uses a 120mm quiet fan to move a greater amount of air at a lower noise level. The wire grill, large quiet fan, heavy duty heatsink, and quiet circuitry all add up to optimum airflow, minimum noise. The NX-4090 quiet power supply provides the user with 400 watts of power for today's power hungry machines, but a silent 16.2 dB(a) of noise in idle mode. The fan, located on the bottom of these quiet power supplies, blows up, rather than out, substantially reducing power supply noise when mounted in your PC.
