Neo HE combines the most desired features in PC power supplies with unprecedented efficiency in design. These new power supplies' energy-efficient operation reduces power consumption by up to 20% compared with traditional power supplies, saving users money. Also generating less heat, and enabling cooling with a smaller, slower, quieter fan. Active PFC circuitry further reduces impact on the power infrastructure. The result is cooler, quieter, and more environmentally friendly power. Accurate power rating allows Neo HE to deliver its full rated power, 24 hours a day rated at 50 degrees C Low-speed 80mm fan delivers whisper-quiet cooling and ensures quiet operation by varying fan speed in response to load and conditions SATA connectors for Serial ATA drives Industrial grade protection circuitry prevents damage resulting from short circuits (SCP), under voltage protection (UVP), power overloads (OPP), excessive current (OCP) and excessive voltages (OVP) MTBF - 80,000 hours Switches - ATX Logic on-off Additional power rocker switch Maximum Power - 500W Leakage Current - less than 3.5mA at 115VAC Dimensions - Length 5.9 x Width 5.9 x Height 3.4 inch, Length 15 cm x Width 15 cm x Height 8.6 cm Weight - 5 pounds, 2.3 kg
