Zalman ZM850-HP
850W ATX12W 2.2 Power Supply
ZM850-HP is an ultra-quiet power supply that complies with ATX12V
Version 2.2, and supports the latest dual-core CPUs (Intel Core2
series/AMD Athlon64-X2 series), as well as the latest dual
graphic card systems (NVIDIA SLI-Ready Certified).
Dual Heatpipes Installed for Maximum Cooling Performance and
Ultra-Quiet Operation:
Dual heatpipes with ultra-high cooling performance incorporated
on the main heat sources enable high load operation even at low
fan 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 Specification.

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.

Four PCI Express VGA Power 6-Pin & 6+2 Pin Connectors:
Four independent 6-Pin Power Connectors (two 6-pin & two 6+2
pin) provide support for Nvidia's Quad SLI.
Module Cables:
Modular cables provide organized cable management and improved
air circulation inside the computer case.
Ultra Quiet 140mm Fan:
The ultra quiet 2 ball-bearing 140mm fan maximizes the airflow
and minimizes the noise level enabling a noiseless computing
environment with optimized cooling.
Standby Noise Filter Switch (**):
The 5Vsb Noise Filter eliminates high frequency noise in standby
mode.
(**) The Standby Noise Filter Switch is NOT a power switch.
The AC Power Cord MUST be unplugged in order to turn the power
supply OFF.

Six Independent +12VDC Outputs:
Six +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 & 16AWG Wires:
All connector terminals are gold-plated to minimize contact
resistance and power lose. 16AWG (thicker than 18AWG) 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, Over-Temperature
Protection.
WEEE & RoHS:
Complies with WEEE (Waste Electrical and Electronic Equipment)
& RoHS (Restriction of Hazardous Substances) environmental
directives of the European Union.
