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).

High Efficiency Design

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.
