As the output voltage of the power supply is same, the output current is larger than the rated current. Can it be used normally?
In fact, the rated current on the device can be understood as the basic operating current, that is, to make the equipment work properly, it is necessary to choose the same size of the current power supply or greater current power supply. As long as the output voltage is consistent, the greater the output current of the power, the greater the power on behalf of the power. The greater the power the better (of course, the greater the power, the more expensive the price)
There are friends with power amplifier and a speaker to compare with high power amplifier for driving a small horn, a burned out, in fact, principle and power audio amplifier is not the same, audio amplifier is to amplify voltage type, output AC (AC) audio signal, audio signal and voltage with the increase of the volume increases, with a small power horn, do not burn, so strange, horn and power amplifier is very important. To sum up, the power supply voltage, current as possible, that the greater the power.OK. but remember not to choose the current than the rated current is small, can be a problem.
300W and 350W electric power and 400W power points, they can be in the computer with each other, the only difference is that if you are computer peripherals, such as mobile hard disk, external recorder, high speed graphics, high frequency CPU, TV card and so on, the power supply only 300W is not capable of consequences, there will be frequent crashes, restart, not the normal use, so the supply of a large power is necessary. From the analysis of the principle, the current size of the demand is depending on the load (i.e. terminal equipment), rather than depending on the power supply, power supply can provide only a maximum current. If the horse is compared to the power supply, the carriage is compared to the load, a strong horse and a small horse pull a carriage together, and the result can be imagined.
