• Up to 54A / 648W available on the +12V rail, respectively 99.6% of the total power
• Designed for powerful operation even at 122°F (50°C)
• Certified for NVIDIA SLI and CrossfireX multi-GPU systems
• ATX12V 2.4 & EPS12V 2.92 compatibility supports the latest generations of processors from Intel® and AMDTM
• Ready for Intel® Haswell™ platform
• Excellent voltage regulation under 2% on the 12V rail

Quiet Zone

• Installed variable speed 135mm SilentWings® fan includes a wide array of electronic and mechanical optimizations for best-of-class air flow with very low noise production
  • Unique airflow-optimized fan blade design reduces noise-generating fan turbulence
  • Advanced fluid dynamic bearing with copper core provides greatly reduced operating noise and super-long life
  • Special 6-pole motor reduces power consumption and vibration
• SilentWings® fan reduces transmission of vibration and noise
• Variable fan speed is optimally governed to strike the best balance between proper cooling and deep quiet

Cooling Zone
