- Less than 1W standby power
- Meets ErP Lot 6, standby power and efficiency standards
- Ultra-quiet 120mm fan
Two-Forward Switching Circuit Design
Two-Forward Switching Design minimises switching loss and internal heat for enhanced reliability and stability.
Active PFC for Improved Power Factor and Reduced Harmonics
By implementing an Active PFC (Power Factor Correction), instead of a Passive PFC with a Power Factor (PF) of 75%, PF has been improved up to 99% while harmful harmonic frequencies have been reduced to meet the Line Harmonic Distortion Requirement of IEC61000-3-2 Class D.
Ultra Quiet 120mm Fan
Ultra quiet 120mm cooling fan increases airflow while minimising noise for a superbly quiet computing environment.
Maximum Efficiency & Energy Savings
The energy efficient Green IC circuitry consumes much less standby power (less than 1W) compared to other PSUs without this feature. The GS PSUs also meet ErP Lot 6 2010 Standby Power, WEEE and RoHS Standards
The latest PSU design standard is incorporated for compatibility with a wide range of CPUs, motherboards, and graphic cards.
Dual Rail +12V DC Output
Two independent +12V outputs for core components facilitate highly stable operation.
Dual Graphics Card Support
One 6 Pin and one 6+2 Pin power connectors for PCI Express support dual graphics card system.
Design Optimised for Cooling
Hexagon-shaped mesh design effective cools the unit and maximises airflow.
Sleeved DC Output Cables
DC Output Cables are sleeved for easy cable management and improved air circulation inside the computer case.
Safe and Stable Power Supply
Safety features include Over-Voltage Protection, Short-Circuit Protection, Under-Voltage Protection, Over-Power Protection safeguard the system.

Zalman ZM500-GS Power Supply
Very good value for money, costing only a few pounds more than my previous budget CIT550w product. The Zalman is well built with individually sleeved & heat shrunk cables of adequate length, enough connectivity for most users and yes as you would expect from Zalman it's quiet, not "silent" but more so than many other budget power supplies on the market. Thank you Quiet PC.
