Zalman ZM-850HP Plus

Dual Heatpipe Cooled Power Supplies

Zalman manufactures premium quiet power supplies. These dual heatipe cooled, bottom mounted, silent power supplies are 80Plus efficient, making them among the quietest and most energy efficient power supplies available. Zalman is also well known for reliability.

ZM850-HP Plus Dual Heatpipes ZM850-HP - Switching Design

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.

ZM850-HP Plus - 80 Plus Silver Certified ZM850-HP Plus 1W Stanby Power

Highly Efficient 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 PSUs without this feature.

ZM850-HP Plus - Erp Ready ZM850-HP Plus - Modular

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

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

ZM850-HP Plus - ATX 12V v. 2.3 ZM850-HP Plus - 4 Independent 12V Outputs

ATX12V v2.3

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.

ZM850-HP Plus - 6+2 Pin Connectors ZM850-HP Plus - Ultra Quiet 140mm Fan

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.


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.


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.


Sleeved Cables

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.

ZM850-HP Plus - MTBF 100,000 ZM850-HP Plus - RoHS

High Reliability

The MTBF exceeds 100,000 hours of continuous operation at 25°C, full load.
