Antec NeoHE 550 High Efficiency 550W Power Supply

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.
