The SmartPower 2.0 PSUs are ATX12V v2.01 compliant and use Antec's dual 80mm fan technology for quiet operation. The 80mm exterior exhaust fan begins spinning for added cooling when the PSU reaches specific temperatures, while the second 80mm fan spins any time the PSU is powered up and is thermally regulated to balance cooling and quietness.
SmartPower 2.0 models come equipped with dual +12V output circuitry for additional system stability and carry UL, CUL, TUV, CB, FCC Class B, CE and CCC certified safety approvals for added safety. Additional features include four Serial-ATA connectors, a PCI Express graphic card connector, and a 24 pin main connector with removable 4 pin section for backwards compatibility.
The 500W model also features Antec's Advanced Cable Management system which allows users to only connect the cables they need, to reduce cable clutter and to improve the airflow inside the case.
The SmartPower 2.0 PSUs are available for $59 to $89, depending on the wattage. They come with a 3 years warranty.
