Antec today announced the Signature Series, its newest and most advanced family of power supply units. Available in 850 Watts and 650 Watts, the Signature Series features several cutting-edge innovations that set it above the competition, several of which have never been offered in a consumer power supply. The Signature 650 and Signature 850 are available now and will retail for estimated street prices of $249.00 and $299.00, respectively.

The Signature Series utilizes active DC-to-DC voltage regulation as opposed to the standard passive magnetic amplifier method, providing for shorter transient response times and greater system stability. The Signature Series' transient response times can be as low as 10 microseconds, in contrast to the standard power supply transient times of 1000 microseconds (1 millisecond). In addition, the Signature Series boasts an advanced cooling system with a Pulse Width Modulation (PWM) fan. By adapting its speed to the power output of the unit, a PWM controlled fan can run at speeds as low as 15% of its maximum, as opposed to a traditional fan which can only run at about 40%, thus ensuring the quietest possible operation.
