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).

Noise Level of ZM460-APS (in dB)

※

The graph above shows that the ZM460-APS in “Noiseless” or “Silent” mode can operate when

the power supply's internal temperature is kept below 56

℃

. This information is in compliance

with the 2nd Revision of ISO7779, an international standard for noise level measurement.

Results may vary for different system configuration and/or the test environment.
