New from Zalman ZM600-HP PSU
 

Check it out! Zalman has created a new modular 600 Watt PSU with 120 mm fan and heatpipes.

I am curious if this one actually is silent. I had a bad experience with their first 400 Watt PSU. That one was not silent!
Now I am using a 420 Watt passive Yesico PSU.





From the Zalman website:

Heatpipe Installed for Maximum Cooling Performance and Ultra-Quiet Operation
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.

Improved Power Factor & Reduced Harmonics through Active PFC
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.

High Efficiency Design
This power supply is capable of reaching a maximum of 84% efficiency(230VAC, Full & Typical Load) through its use of high switching frequency and low power-loss circuitry.

ATX20+4 Pin Main Connector
ATX20+4 pin main connector broadens the range of motherboard compatibility.

Supports ATX12V CPU 4-Pin and EPS12V CPU 8-Pin
Two ATX12V CPU 2¥ª2(4-Pin) power cables can be combined to form an EPS12V CPU
8-Pin power cable.

Dual PCI Express VGA Power 6-Pin Connector
Support Nvidia SLi dual graphic card systems.

Module Cables
Modular cables provide organized cable management and improved air circulation inside the computer case.

Ultra Quiet 120mm Fan
Ultra quiet 2-Ball Bearing 120mm fan maximizes the airflow and minimizes the noise level enabling a noiseless computing environment with optimized cooling.

Four Independent +12VDC Outputs
Four +12VDC rails supply power independently to the CPU, VGA, motherboard, and peripheral
components for the highest level of stability and performance.

EZ Grip Connectors for ODDs & HDDs
EZ Grip Connectors for easy removal of the plugs from ODDs & HDDs.

Gold-Plated Terminals
Gold-plated the terminals minimize power loss by reducing contact resistance.

Sleeved Cables
All power cables are sleeved for easy cable management and improved air circulation inside
the computer case.

Multiple Safety Features
Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, Over-Temperature Protection.

Internal Blue LED
Blue LEDs are installed inside the power supply for cool aesthetics.

WEEE & RoHS
Complies to WEEE & RoHS Environmental Directives of Europe.

- WEEE : Waste Electrical and Electronic Regulations
- RoHS : Restriction of Hazardous Substances Regulations
