4. The Zalman Advantage

Zalman

’

s  CNPS*  products  enable  a  noiseless  computing  environment,  in  accordance  with  our  policy  of

developing  people-friendly  products.  This  ultra-quiet  power  supply  complies  with  ATX12V  Version  2.2,  and
supports the lastest dual-core CPUs(Intel Core2 series/AMD Athlon64-X2 series), as well as the lastest dual
graphic card systems(SLI/CrossFire).   

CNPS  (Computer  Noise  Prevention  System)  refers  to  a  system  that  reduces  a  conventional  computer

’s

noise level (30dB or more) to an inaudible level (20dB or less).  Zalman

’s silent/ultra-quiet computers of the

highest quality.

▣

A heatpipe with ultra-high cooling performance incorporated on the power supply

’s main rectifiers enables

high load operation even at low RPM for a dramatic reduction in noise levels.

▣

▣

By  implementing  Active  PFC(Power  Factor  Correction),  the  Power  Factor  (PF)  is  improved  from  75%
(Passive  PFC)  up  to  99%  while  harmful  harmonic  frequencies  are  reduced  to  meet  the  line  harmonic
distortion requirements of  IEC61000-3-2 Class D. 

▣

▣

This  power  supply  is  capable  of  reaching  a  maximum  of  81%  efficiency(230VAC,  Full  &  Typical  Load)
through its use of high switching frequency and low power-loss circuitry.
