NEXUS NX-3500 Power Supply - Quiet 350 Watt PSU
More airflow, less noise.
This is an amazingly quiet power supply! 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! In fact, in tests in our own quiet computers, CPU temperatures dropped as much as 10 degrees
Celcius during 100% CPU load testing. This temperature drop is based on a comparison between the NX-3500 and quiet power supplies equipped with 80mm fans and already designed for proper airflow.
Because of its incredible airflow, this quiet power supply is well-suited for today's 3 Ghz and above quiet pcs.
The NX-3500 quiet power supply designed by NexusTek is the latest in innovation and efficiency. The NX-3500 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-3500 quiet power supply provides the user with 350 watts of power for today's power hungry
machines, but a silent 19.2 dB(a) of noise. 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.
