Zalman ZM-750-HP 750 Watt Quiet Power Supply

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 noiseless
solutions enable the user to build silent/ultra-quiet computers of the highest quality.

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 up to 99% while harmful harmonic frequencies are reduced to meet
the Line Harmonic Distortion Requirement of IEC61000-3-2 Class D.

High Efficiency Design and 80 PLUS Certified  
This power supply is capable of reaching a maximum of 86% efficiency (230VAC, Full & Typical Load) through its use of high switching frequency and low
power-loss circuitry. This product has been certified with the 80 PLUS Power Supply Certification and guarantees a higher efficiency compared to uncertified
products.  
* 80 PLUS is an innovative, electric utility-funded incentive program that strives to integrate more energyefficient power supplies into desktop computers and
servers.

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 2×2(4-Pin) power cables can be combined to form an EPS12V CPU 8 Pin power cable.

6 Pin Power Connector for Two PCI Express Graphic Cards  
Two independent 6-Pin power connectors fully support Nvidia’s SLI and ATI’s CrossFire.

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

Ultra Quiet 120mm Fan  
The 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 and 16AWG Wires  
All connector terminals are gold-plated to minimize contact resistance and power lose. 16AWG (thicker than 18 AWG)wires are incorporated to minimize voltage
drop during high load operation.

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, and Over-Temperature Protection.

Internal Blue LED  
Blue LEDs are installed inside the power supply for cool aesthetics and let's you know PSU is on.

WEEE & RoHS  
Complies with WEEE & RoHS environmental directives of the European Union.

- WEEE (Waste Electrical and Electronic Equipment)
- RoHS (Restriction of Hazardous Substances)
