NVIDIA™ SLI™-R EADY C ERTIFICATION
Antec’s TruePower Quattro power supplies are NVIDIA™ SLI™-Ready certified for use with multiple high-end
graphics cards for superior parallel graphics processing.
A DVANCED H YBRID C ABLE M ANAGEMENT S YSTEM
The TPQ-1200 uses Advanced Hybrid Cable Management. Cables that are important or mandatory are connected
directly to the PSU. There are also modular connectors on the back of the PSU to add additional cables as needed.
Using only the power cables you need will reduce clutter and improve airflow inside your case. For the list of
connected and optional cables, see Table 3.
DC TO DC C ONVERSION
The TPQ-1200 uses DC to DC conversion for the +5V and +3.3V rails. This module operates at 85% efficiency, as
opposed to traditional magnetic amplifiers that operate at only 75% efficiency. Transient response time is almost
100 times faster, providing remarkably stable power output in response to changing loads.
P ULSE W IDTH M ODULATION (PWM) F AN
Pulse Width Modulation technology allows the TPQ-1200 to finely control the speed of the PSU’s fan. By using this
method instead of the traditional voltage-controlled fans, this PSU’s fan can run up to 50% quieter than standard
fans. 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%.
+12 V OLT R AIL D ISTRIBUTION
The TPQ-1200 uses six separate +12 volt power rails. The engineers have allocated the rails to different connectors
to prevent voltage sags in one device due to sudden demands for power by another device.
