[High amperage single plus 12V rail] - Ensures a stable and reliable supply to other PC components. [Strict voltage regulation] - <2% Voltage regulation for major rails to meet the highest performance, compared to Intel's standard 5%. [Less than 30 mV low ripple noise] - Low ripple ensures excellent performance and keeps performance-critical components, such as high-end graphic card, operating reliably longer. [Zero cable platform] - Daughterboards are directly soldered to the Motherboard for better heat dissipation and impressive output power quality. [Japanese capacitors] - 100% High quality 105°C (221°F) Japanese capacitors offer the highest stability, durability, and reliability. [16AWG wires] - Upgraded CPU/PCI E main cables (16AWG wires) for high end enthusiasts' Pcs. [Smart zero fan] - Auto-regulated fan speed based on power consumption for a quiet and efficient operation. Fan works only when PSU work load goes over 30%. a switch At the back of the PSU can be turned off to have the fan spun constantly. [Ultra quiet 140mm hydraulic Bearing fans] - Self-lubricated hydraulic Bearing PWM fan superior cooling performance and near silent operation. [80 plus gold and Intel C6/C7 States ready] - Deliver up to 90% efficiency, Gf1 Series optimized to work with all generations of Intel's processors to achieve maximum energy saving.
