System Protection:

If the power supply latches into shutdown stage (when over current, over voltage or short circuit protection is working), the power supply shall return to normal operation only after the fault has been removed and PS-ON is reset for a minimum of 1 second or by removing AC power cord and reconnect it.

Over Current Protection
The power supply DC outputs are protected from supplying output current above the maximum ratings and when output power is between 110%~150%. With the exception of the +5VSB output, all DC outputs are latched off in the event of an over-current event on any of the DC outputs. In the event of a short circuit on any output, except the +5VSB rail, all outputs are disabled and remain disabled until the power supply is powered off and back on. The +5VSB rail will recover upon removal of the over current condition.

Over Voltage Protection
The over voltage protection sense circuitry and reference reside in packages that are seperate and distinct from the regulator control circuitry and reference. No single point fault is able to cause a sustained over voltage condition on any or all outputs. The power supply provides latch mode over voltage protection defined as:
+5V output is between 5.8V to 6.3V
+12V output is between 14.0V to 17.0V
+3.3V output is between 3.6V to 4.2V

Short Circuit Protection
The power supply DC outputs are protected from damage due to faults, when any output shorts to ground. In the event of a short circuit on any output, all outputs shall be disabled and remain disabled until the power supply is powered off and back on. The 5VSB rail will recover upon removal of the over current.

Features:

Exactly as printed on the box.

  • 80+: This PSU delivers more than 80% efficiency. Low power consumption both saves energy (and money) and makes power supply to work cooler. So components' life time increases.
  • Game: Gaming systems need high qaulity VGA cards, and these cards need high current levels. This power supply is designed and optimized to deliver better current to support such systems.
  • Modular: Modularity allows users to install just needed cables and remove unusable ones to make system case bulky and provide better air flow.
  • ATI Crossfire and Nvidia SLI: One PCI-E 6 pin and one PCI-E 6+2 pin connectors are provided to allow crossfire and SLI systems. These connectors are connected to high quality powerful transistor to deliver enough current to modern high-end VGA cards.
  • Active PFC: Active PFC circuitry effectively regulates input voltage to deliver superior operation in a wider range of environments and countries with varying voltages.
  • Silent operation: Eliminates noise assuring silent operation, yet no sacrifice to power delivery.
  • EMI Solution: Two step full EMI circuit plus one choke make three steps to filter entire input noise as well. In this way no noise enters to first stage of the power supply.
  • PCI-E 6+2 pin: The 6+2 pin PCI-E connector makes users able to use either 6 pin or 8 pin VGA cards.
  • Protection Guard: Over Current, Over Voltage, Under Voltage, Short Circuit, Over Temperature, No Load Operation, Anti Lighting, Power Protection.
  • Clean Powerful 12V: In this PSU, +12V voltage has been enhanced to be able to deliver maximum current and clean 12V voltage to enhance performance for CPU and VGA cards.
  • Supports all kinds of Processors: This PSU supports all kinds of systems based on Intel and AMD processors manufactured till now: Intel Core 2 Duo, Intel Core 2 Quad, Intel Core i5, Intel Core i7, AMD Athlon, AMD Athlon II, AMD Phenom and AMD Phenom II processors.
