Antec Signature Series
SG-650 and SG-850 Power Supply
A New Level of Quality
The Signature Series is Antec’s premium line of high-end performance power supplies. Combining cutting-edge technology, rigid testing, and impeccable style, the Signature series is the ultimate choice in power supplies. Some of the design features in this premium quality PSU have never been seen before in a consumer power supply. Every Signature series power supply has been personally tested by our engineers, and comes with a signed document guaranteeing its quality performance.
Standards and Features
The Signature Series Power Supply Unit (PSU) is compatible with ATX12V v2.3 and EPS12V v2.91 specifications. The Signature PSU features Universal Input, which automatically senses when you connect the power supply to any AC power source between 100~240V without having to worry about setting a voltage switch.
This power supply also features Active PFC, which improves the power factor value of the power supply by altering the input current wave shape and thus helps transmission across the power grid.
Components and Design
Antec has selected only the best quality Japanese capacitors enhancing the unit’s stability and increasing the MTBF of the Signature. The component choice has been expanded by the use of two double-layer circuit boards, which allow for heavier-duty components and more space between them for better airflow. The fan is a top-quality Japanese made PWM fan.
DC to DC
The Signature uses DC-to-DC conversion for the 5V and 3.3V rails. The DC-to-DC Voltage Regulation module is the most advanced design, usually found on high-end motherboards, to step down DC voltage. This module operates at 85% efficiency, as opposed to a traditional Magnetic Amplifiers that only operate at 75% efficiency. Another benefit is that the transient response time is almost 100 times faster, to provide unbeatably stable power output in response to changing loads.

System Protection
A variety of industrial-grade safety circuitry will help protect your computer: OVP (Over Voltage Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Sometimes the PSU will “latch” into a protected state. This means that you will need to clear the fault and turn the power off to the PSU before it will function again. There are no user-replaceable fuses in your Signature Series PSU.
Special Quiet Computing™ PWM fan operation
Another innovation in your Signature is the introduction of pulse width modulation (PWM) fan technology. A PWM fan can spin much more slowly and be quieter than a voltage-controlled fan. The Signature uses a Japanese PWM fan that can spin as slow as 400 RPM or as fast as 4000 RPM, depending on load and ambient temperature. It should be nearly inaudible when your computer is idling, and the Signature will vary the fan speed depending on the load of your computer.
80 PLUS® Bronze Certification
80 PLUS® Certification is the latest independent standard in power supply efficiency. This means that the PSU will generate less heat so it stays cooler, runs more quietly, and lasts longer. The Signature series exceeds the basic 80 PLUS® standard and lowers your operating costs while protecting the environment.
SLI Certification
Signature power supplies have been SLI Certified by NVIDIA Corporation for use with pairs of high-end graphics cards for superior parallel graphics processing.
Advanced Hybrid Cable Management System
The Signature Series 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 the following table.
