Remark

1.       All parameters are specified at 230VAC input, rated load 25   70% RH ambient;

2.       Ripple & noise are measured at 20MHz by using a 12’’ twisted pair terminated with a 0.1uF   &47uF capacitor;

3.       Tolerance: includes set up tolerance, line regulation and load   regulation;

4.       Line regulation is measured from low line to high line from the rated   load;

5.       The over temperature protection is the built in function of the control   IC.

Q: Is there such a thing as "too much power" for power supplies?

 

A: Generally, not A power supply only puts out as much power as needed by the system's components. In some cases, an 800W power supply may actually use less power from the wall than a 500W power supply, depending on the efficiency of the units. Often times, buying an "oversized" PSU is a good choice due to it's ability to perform even under higher temperatures, a quieter fan because the unit is delivering a lower percentage of it's total capability and considerable system upgradeability without having to worry about having enough power when upgrading a graphics card, adding a graphics card for SLI or additional hard drives.

 

Q: What should I consider when selecting a Power Supply Unit (PSU)?

 

A: Efficiency and Reliability are the two most important factors to consider in selecting a PSU.

The best way to ensure the reliability of the PSU is to choose one that provides a maximum of 30% more output than your actual total requirement. For example, if your system has a 90W power requirement, you should choose a PSU with at least 120W power output rating. By doing so, you are boosting the reliability of the PSU as well as prolonging the entire system life.
