EVGA POWER SUPPLIES

Industrys Highest Quality Components

Built to be the Best

  • The main MOSFET functions as a switch for the half-bridge LLC converter. This gate switch turns on to load, and then switches off to deliver the power for conversion. Using the correct high-quality MOSFET allows the DC-DC conversion to be as efficient as possible.
  • There are many capacitors on a power supply, but the main capacitor is the most important due to the amount of power stored at any time. Japanese capacitors, including those from Nippon Chemi-Con, are tested to the highest standard in the power supply industry, ensuring reliability and durability
  • Hydrodynamic Bearings are a type of fluid bearing for fans. Fluid dynamic bearing fans rely on a thin-layer of fluid between the bearings to create lower friction, wear, and vibration. Hydrodynamic bearings use the shaft to pressurize the fluid to create the barrier between the bearings. This method reduces noise and vibration.
  • The EVGA fan blade uses a thin blade to cut through the air, delivering cooling to the power supply, while keeping noise to a minimum. The E-logo is printed on the blades as yet another means to show attention to detail.
