Zalman ZM-300A APF

Features:

With the goal of enhancing the computing environment, all Zalman Tech products are noise-free. This product is a noise-free 300W ATX (version 2.03) / ATX12V power supply supporting Intel Pentium, AMD, VIA CPUs.

The Zalman Advantage:

• 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.

* When the temperature inside the power supply is 55Deg C or less, the cooling fan will operate in 'Quiet' or 'Silent' mode.

* 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.

• Simplifying Source Input - Free Voltage
Unlike products with Passive PFC, where you have to set the operating voltage (115VAC / 230VAC) with a manual switch, this product can be used with any normal AC input source ranging from 100VAC to 240VAC.

• Certified with Safety Approval EMC Standards - UL, C-UL, CE, TUV, CB-NEMKO, FCC

• Improving Power Factor & Eliminating Harmonics through Active PFC
By implementing Active PFC, the power factor (PF) is improved from 75% (Passive PFC) to 94% (at full load), while harmful harmonic frequencies are reduced below regulatory requirements.

• Supplies Stable Power to Intel Pentium 4
By including a ATX12V 2x2 (4-pin) 12V power connector and an auxiliary 5-pin power connector, this product can provide stable power to Intel Pentium 4 CPUs, which need 6A of current from each power rail.

• High Efficiency Power Supply
Designed with a high switching frequency and low power-loss circuitry, the efficiency of this product exceeds 75% (at full load).

How to Use:
The Muti-connector, included free in every Zalman power supply, is used to supply +5V or +12V power to any additional fans that a user may wish to install. Connect it to the power supply's output connector (P9) and simply attach the fans to the 3-pin connectors at the other end.

Components:

1. One Power Supply
2. One Multi-connector 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 Manual

Please Keep in Mind for Building a Noiseless Computer:

Zalman Tech provides Noise Prevention (NP) power supplies, CPU coolers, and case fans, as well as fan-less northbridge coolers and video card coolers to bring you stable performance into noiseless environment.

Precaution:

* To ensure safe and easy installation, first read the Safety Precautions above and then read the following notes.

1. 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.

2. Do not insert the DC output connectors too forcibly into devices as the shape of the connector is
meant to prevent incorrect insertion.

3. If, after installing the product, the Power On light on the case does not light up when the main
power button is pressed, some devices may be plugged in incorrectly or the mainboard may be
faulty. Please double-check the installation.
