Features:

 

There are quite a few features on the back of the packaging, under three different headings, here they are:

 

Performance Features:

 

  • Up to 85% efficiency & low power consumption
  • RoHS ready and environmental friendly
  • 3.3V DC to DC VRM layout design to enhance stability and efficiency
  • Double forward converter design for highest efficiency and best stability
  • Active power factor correction (>0.99%), reduce line loss & power distribution
  • MTBF > 100,000 hours
  • High reliable Japan made main capacitors, increase product life & reliability
  • Tuned for best silence performance
  • Dual magnetic amplifiers, improve cross regulation tolerance on +12V rails in 3% for optimized stability
  • Bead core protection on PCI-E connectors to minimise EMI for reducing noises

 

Flexibility Features:

 

  • Complies with the latest ATX 12V V2.3 & EPS 12V V2.91
  • Supports Intel dual and quad core CPU
  • Supports AMD dual and quad core CPU
  • Supports SLI and Crossfire Multi-GPU graphics card (PCI-E 2.0 Compliant)
  • Easy swap connector for easily & quickly unplugging
  • Universal AC input (full range), plug & run safely at 90-240VAC
  • Short circuit protection (SCP), over voltage protection (OVP), under voltage protection (UVP), over current protection (OCP), over temperature protection (OTP) and over loading protection (OLP) for your hardware safety
  • Cable management increases airflow, better cooling performance

 

Silence Features:

 

  • 135mm ball-bearing cooling fan, increases airflow, better cooling performance, reduces rotation speed and noise level (17dBA)
  • Ultra ventilation design, honey comb vent for minimized airflow resistance for maximum cooling
  • Smart & silent fan control, thermal control to balance noise and cooling
  • Sleeve cable for minimized airflow resistance for maximum cooling

 

Lian-Li certainly get the prize for the longest feature list so far!
