3. Notes on Installation

1) One Power Supply

2) One FAN Multi-connector (ZM-MC1)

󳢹 (For supplying power to an extra fan. See page 5 for details.)

3) One S-ATA power convert cable

4) One PCI-Express VGA SLI sub-Cable for power conversion

5) One Power Cord for AC Power Source (Not included in some countries)

6) One User's Manual

7) Zalman Cable Tie

※ To ensure safe and easy installation, first read the Safety Precautions above, 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 with too much force into devices as the shape of the connector

is meant to prevent incorrect insertion.

▣ After installation, if 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 main board may be faulty.
Please double-check the installation.

4. The Zalman Advantage

With the goal of enhancing your computing environment, all Zalman Tech products are ultra-quiet.
This product is an ultra quiet 460W ATX Ver. 2.03 / ATX12V Ver. 2.01 power supply supporting
SLI-capable Intel LGA775 Pentium 4 & AMD Athlon 64/64 FX CPU equipped systems.

By implementing heat-sensor circuitry that controls the cooling fan’s speed (rpm) in relation to
the temperature within the power supply, 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 other noise-free products should be used together with this product.

▣ CNPS (Computer Noise Prevention System) with Auto Control Cooling Fan

By implementing Active PFC, the power factor (PF) is improved from 75% (Passive PFC) to 96%
(230VAC, Full load), while harmful harmonic frequencies are reduced below regulatory requirements.

▣ Improving Power Factor & Eliminating Harmonics through Active PFC

Designed with a high switching frequency and low power-loss circuitry, the efficiency of this
product exceeds 80%

(230VAC, Full load).
