CB-1050W

80 PLUS® Platinum Certified Power Supply

The CB Series delivers up to 92% conversion efficiency. This power supply with a new circuit design is able to maintain consistent conversion efficiency even under low loading conditions.

Ultra Quiet Smart Fan Control Design

The CB Series utilizes a smart temperature-controlled fan design. It has built-in control modes for three temperature ranges and automatically detects the output power to adjust the fan speed accordingly.

Silent Fan Mode

Cooling Mode

Shut Down Cooling Mode

 
 
 
 
 

When the system is under 25% load, the fan will automatically stop running to effectively reduce the system’s noise.

The CB Series features an automatic power detection output. When the system is above 25% load, the fan will automatically turn on to maintain optimal cooling.

The CB Series possesses a shutdown cooling feature. When the system is shutdown, the fan will continue to operate for 60 seconds to effectively remove residual heat.

Digital Voltage Feedback Design

The MCU digital voltage feedback control design is able to control the voltage output fluctuation at <+/-2% to provide consistent voltage output.

5V and 3.3V DC to DC Design

The CB Series’ DC to DC converter design provides a superior dynamic response, and supports a foundation for greater system stability.

Full Modular Design

The fully modular and slim cable design simplifies installation and allows you to use only the cables you need, for a neater, cleaner build.

Highly Reliable Japanese Electrolytic Capacitors

Premium Japanese capacitors with 105 °C rating improves power stability at higher temperatures and provides an ultra-long lifespan.
