SKU: ZM500RS
RETAIL: $114.95
PRICE: $114.95

The new Zalman ZM-500 RS rock solid PSU is now available with advanced resonant switching. With its high efficiency proven by 80 Plus certification, this power supply will bring stable power to demanding quiet computer systems. Resonant Switching will have no power loss during on/off operation, so that the power can be operated in an optimized environment.

Resonant Switching Circuit Design

• More advanced than 'two-forward' switching, resonant switching minimizes switching power loss and dramatically reduces internal heat generation offering the highest level of reliability and durability.

80 PLUS® Certified High Efficiency Design

• This power supply is capable of reaching a maximum of 87% maximum efficiency (230VAC, Typical Load) through its high switching frequency and low power-loss circuitry design, and is 80 PLUS® certified, guaranteeing higher efficiency compared to uncertified products. 80 PLUS® is an energy efficiency certification program administered by Ecos Consulting of the U.S.A.

ATX12V v2.3

• Implementing the latest standards, the ATX12V v2.3 specification offers the latest CPU, motherboard and graphic card compatibility.

Dual Rail +12V DC Output

• The +12C DC output is supplied by 2 rails for stable operation of core components.

Supports Dual Graphic Card System

• 6-Pin and 6+2-Pin PCI-E connectors are provided for dual graphic card systems.

Ultra Quiet 120mm Fan

• An ultra quiet Hydro Bearing cooling fan increases airflow while minimizing noise for a superb ultra quiet computing environment.

Active PFC for Improved Power Factor & Reduced Harmonics

• 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.

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 2x2(4-Pin) power cables can be combined to form an EPS12V CPU 8-Pin power cable.

Multiple Safety Features for the Highest Level of Safety

• Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection features protect the system from potential electrical hazards

WEEE & RoHS Compliant

• Complies with WEEE & RoHS environmental directives of the European Union.
• WEEE (Waste Electrical and Electronic Equipment)
• RoHS (Restriction of Hazardous Substances)
• International Safety and EMC Certifications

Cautionary Warning

Plugging the main power connector P1 into the motherboard while the product is connected to the AC power source may result in damage to the motherboard.

Make sure that the connectors are connected to their designated locations, and that the connectors are not oriented in the wrong direction when connecting the DC output connectors.

If the Power On light fails to light up when the main power button is pressed after completing the installation procedure, then some devices may be plugged in incorrectly or the motherboard may be faulty.
