Caution
2. Components
1) One Power Supply
2) One Multi-connector(ZM-MC1) for Fan
(Use this to supply power to extra fan. See page5 for details.)
3) One Power Cord for AC Power Source (Not included in some countries)
4) One User’s Manual
3. Notes on Installation
※To ensure safe and easy installation, first read the Safety Precautions above and then read the following notes.
▣
Plugging the main power connector P1 into the main board while the product is connected to the AC power
source may result in damage to the main board.
▣
Do not insert the DC output connectors too forcibly into devices as the shape of the connector is meant to
prevent incorrect insertion.
▣
If, after installing the product, the Power On light on the case does not light up when the main power button is

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 IntelPen tium
4 and AMD CPUs.
▣
Realizing a Noise-Free Computing Environment (CNPS) with Auto Control Cooling Fan
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 m anufacturers
should be used together with this product.
Fig.1: Noise Level(dB) Changes In relations to Power Supply's Internal Temperature
1) Noise Level (dB) of ZM300B-APS 2) Noise Level (dB) of ZM400B-APS
※ 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
of ISO7779, an international standard for noise level measurement. Results may vary for a different system
configuration and/or the test environment.
▣
Complies with Intel ATX12V Ver. 1.3
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.
