Zalman ZM850-HP Plus Dual Heat-pipe Cooled ULTRA Quiet Computer Power Supply
Dual Heatpipes for Maximum Cooling Performance and Minimum Noise
Dual heat-pipes with ultra cooling performance are incorporated on the main heat source, thus enabling high load operation at low fan RPM and dramatically
reducing noise levels.
Two-Forward Switching Design
The Two-Forward Switching Design minimizes switching loss and internal heat for enhanced reliability and stability.
Highly Efficienct Design and 80 PLUS® Silver Certified
This power supply is capable of reaching a maximum of 90% efficiency (230VAC, Full & Typical Load) through its use of high switching frequency and low power-
loss circuitry. This product has been 80 PLUS® Silver certified and guarantees higher efficiency compared to uncertified products.
※ 80 PLUS ® is an energy efficiency certification program administered by Ecos Consulting of the U.S.A.
Less Than 1W Standby Power Consumption
The energy efficient Green IC circuitry consumes much less standby power (less than 1W) compared to other PSU’s without this feature.
Meets ErP Lot 6 Standby Power Standards (ErP: Energy-related Product)
This product complies with ErP Lot 6, the Standby Power and High Energy Efficiency standards of the European Union.
Modular cables provide organized cable management and improved air circulation inside the computer case.
The latest PSU design standard is incorporated for compatibility with a wide range of CPUs, motherboards, and graphic cards. Four +12V DC Outputs
Four independent +12V outputs provide a stable power supply to major PC components.
Dual & 3-Way Graphics Card Support
Three 6-Pin and three 6+2 Pin power connectors for PCI Express support dual and 3-way graphics card system.
Ultra Quiet 140mm Fan
A Two-Ball Bearing fan maximizes airflow while minimizing noise for a superbly quiet computing environment.
Active PFC for Improved Power Factor & Reduced Harmonics
By implementing Active PFC (Power Factor Correction), the Passive PFC ( about 75%) has been improved up to 99% while harmful harmonic frequencies are
reduced to meet the Line Harmonic Distortion Requirement of IEC61000-3-2 Class D Specifications. Japanese-made Capacitors
Japanese capacitors are incorporated in the 1st stage of smoothing circuit for reliability and stability even after an extended period of operation.
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.
All power cables are sleeved for easy cable management and improved air circulation inside the computer case. EZ Grip Connectors for ODDs & HDDs
EZ Grip Connectors allow convenient installation to ODDs & HDDs.
Gold-Plated Terminals & 16AWG Wires
All connector terminals are gold-plated to minimize contact resistance and power loss. 16AWG wires, thicker than 18AWG, are incorporated to minimize voltage
drop during high load operation. Multiple Safety Features
Safety features including Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection
safeguard the system.
The MTBF exceeds 100,000 hours of continuous operation at 25℃, full load. Meets WEEE & RoHS Standards
This product complies with the WEEE & RoHS environmental directives of the European Union.
