CNPS (Computer Noise Prevention System) 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, 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.

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. |
Improving Power Factor & Eliminating Harmonics
through Active PFC
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.
High Efficiency Design
Designed with a high switching frequency and low power-loss circuitry,
the efficiency of this product exceeds 80% (230VAC, Full load).
ATX “20+4”-Pin Main Connector
ATX “20+4”-Pin main connector broadens mainboard compatibility.
ATX12V CPU (4-Pin) & EPS12V CPU (8-Pin)
Connectors
Use two ATX12V 2ⅹ2(4-pin) connectors together to form an EPS12V CPU
connector(8-pin).
PCI Express Graphic Card Power
Connector(6-Pin)
PCI-Express graphics card power connector is provided to high-end
graphics card support.
EZ Grip Connectors for ODD & HDD
