The Ultimate High 
End Power Supply

The Signature Series is Antec’s premium line of high-end perfor-
mance power supplies. Combining cutting-edge technology, rigid 
testing, and impeccable style, the Signature Series is the ultimate 
choice in power supplies. 

Voltage Regulator Modules:

The Signature Series utilizes Voltage Regulator Modules instead 
of magnetic amplifiers for the 3.3V and 5V outputs. This leads to 
very short transient response times within the power supply, 
which in turn leads to greater system stability. In fact, with the 
Signature Series, transient response times can be as low as 10 
microseconds compared to the typical power supply transient 
response times of 1 millisecond. 

Pulse Width Modulation (PWM) fan:

Pulse Width Modulation technology allows the Signature Series 
to finely control the speed of the power supply's fan. By using 
this method instead of the traditional voltage controlled fans, 
Signature Series power supply fans can run up to 50% quieter.  
How does a PWM fan do this?  A PWM fan can run as slow as 
10-15% of the fan’s rated top speed, whereas a voltage regulated 
fan can only go as low as 40%.  Using PWM also allows the use 
of higher speed fans with a minimal increase in generated noise.  

Japanese made components:

The Signature Series is made with a Japanese fan and Japanese 
capacitors.  The use of these components helps ensure that 
Signature Series power supplies have a long and reliable life.

Dual double layer PCB layout:

Designed with two double layer PCBs, the Signature Series 
utilizes a low density component layout to provide better airflow 
throughout the case. In addition, dual PCBs allow for heavier 
components, create less electrical noise and ensure greater 
reliability.

80 PLUS®

The Signature Series passes 80 PLUS®, the highest independently 
certified standard in energy efficiency. This enables it to lower 
operating costs and protect the environment.
