"The Antec HCG-620W power supply is in the middle of the High Current Gamer pack. The Antec HCG-620W is 80 plus bronze certified and comes with full industrial-grade protection, including over-voltage, over-current, short-circuit and over-power protection. Internally, the Antec HCG-620W uses all Japanese brand capacitors for reliability and is equipped with a 135 mm fluid dynamic-bearing fan for quieter performance and longer lifespan compared to the standard sleeve-bearing fan. For peace of mind, the High Current Gamer 620W power supply also comes with Antec’s Quality warranty, which covers performance failure up to 3-years from the date of purchase."
