4. The Zalman Advantage
With the goal of enhancing the computing environment, all Zalman Tech products are noise-free.
This product is a noise-free 300(400)W ATX Ver. 2.03 / ATX12V Ver. 1.3 power supply supporting IntelPentium
4 and AMD CPUs.
By implementing heat-sensor circuitry that controls the cooling fan’s speed (rpm) in relation to the
temperature within the power supply, emanating noise has been greatly reduced. The graph below shows
the CNPS characteristics of our product.
※
CNPS (Computer Noise Prevention System) refers to a system that reduces a conventional computer’s
noise (30dB or more) to an inaudible level (20dB or less). In order to create a true noise-free computer,
Zalman’s NP CPU Cooler and NP Video Card, along with an NP HDD from popular manufacturers
should be used together with this product.
※
The above results show that the Zalman product operates in ‘Noiseless’ or ‘Silent’ level when the power
supply's internal temperature is kept below 56
℃
and those were obtained in compliance with the 2nd Revision
of ISO7779, an international standard for noise level measurement. Results may vary for a different system
configuration and/or the test environment.
This is the latest product in our power supply line-up, designed to comply with Intel ATX12V Ver. 1.3
S-ATA power connectors supporting S-ATA Ver. 1.0 compliant hard disk drives are provided as standard.
For information on how to use the S-ATA power connector with a S-ATA HDD, please refer to
the output power cable diagram on page 5.
