Introduction
CNPS
(Computer Noise Prevention System) with Auto Control
Cooling Fan
Noise has been greatly reduced with the implementation
of the heat-sensor circuitry, which is in control
of the cooling fan’s speed (rpm) in relation
to the temperature, inside the power supply.
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.
[Noise
Level (dB) Changes In relations to Power Supply's
Internal Temperature]
The graph above shows that the ZM460B-APS in “Noiseless”
or “Silent” mode can operate when the
power supply's internal temperature is kept below
45°C.
This information is in compliance with the 2 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 & Reduced Harmonics through Active
PFC
By implementing Active PFC, the power factor (PF)
was improved from 75% (Passive PFC) up to 96% (230VAC,
Full load), while harmful harmonic frequencies were
reduced below regulatory requirements.
High
Efficiency Design
The efficiency of this product exceeds 80% (230VAC,
Full Load) with the use of high switching frequency
and low power-loss circuitry.
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).
Dual
PCI Express VGA Power Connectors (6-Pin)
Two PCI-Express VGA power connectors are provided
to support high-end graphic cards
(Nvidia SLI & ATI Cross-Fire). (It may not support
certain graphic cards depending on their specifications.)
NMB-MAT
120mm Fan
Fan’s noise level can be kept constant compared
to other products even if used for a long duration
by employing the 2-Ball Bearing 120mm fan of NMB-Matsushita
known for their great
endurance and excellent reliability.
Dual
+12VDC Output
Two +12VDC rails of combined output up to 34A(Only
ZM460B-APS) provide more stable power to high-end
systems.
EZ
Grip Connectors for ODD & HDD
EZ Grip Connectors for ODD & HDD for easy connecting
and disconnecting of the plugs.
Use
of gold-plated terminals
Minimized power loss with reduced contact resistance
by gold-plating the terminals of all connectors.
WEEE
& RoHS
Conforms to WEEE & RoHS Environmental Directives
in Europe.
- WEEE : Waste Electrical and Electronic Regulations.
- RoHS : Restriction of Hazardous Substances Regulations.
Sleeved
Cables
All power cables are sleeved for easy cable management
and improved air circulation inside the computer
case.
