Remark

1.       All parameters are specified at 230VAC input, rated load2570% RH ambient;

2.       Ripple & noise are measured at 20MHz by using a12’’ 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: What is a "power supply"?

 

A: Different components require different DC voltages. Cities' power grids provide alternating current. So, for devices to receive the electricity it needs to function, we not only need to convert AC to DC power, but we also need to convert the AC into several different DC voltages.

 

To do this, computers use a "power supply", often called PSU for short (the "U" stands for "Unit".) Computer power supply units are of the "switch mode" variety and are capable of providing several different DC voltages at very high current while still remaining relatively small in size and efficient.

 

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

 

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 upgradability without having to worry about having enough power when upgrading a graphics card, adding a graphics card for SLI or additional hard drives.
