We are pleased to present Zalman’s unique range of heatpipe-cooled power supplies. By using a heatpipe-based heatsink inside the PSU itself, Zalman have managed to give the product unparalleled cooling ability meaning that its fan can run reasonably quietly and the efficiency of the unit is very high (up to 86%!).
The units also feature a modular cable harness system. This allows you to remove those cables which aren’t needed, improving the appearance, maintainability and airflow inside your PC case. The PSUs come with a generous 3-year warranty and the 500W and 600W units have a cool blue LED effect too. If you have been holding out for your next power supply upgrade, or wondering what PSU to use in your new dual-core system, now you have the answer!
If you are considering purchasing the ZM850-HP, please ensure that you have sufficient space inside your case to accomadate its extra length. This unit is 60 mm longer than a standard PSU.

Features
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?2(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.
Two Independent +12VDC Outputs
Two +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.
