Power Supplies With More Wattage Consume More Power!

This myth has been the doom of many poor PCs due to overloading. This is just one of those myths that cause people more heartache than any other myths, all because this myth involve the power supply of the PC. The power supply can be equated as the heart of the human body, pumping blood (aka power) to the organs.

Power supplies with more wattage DO NOT consume more power. Switching power supplies deliver power based on load. In layman terms, that means the power supply only outputs the power that is needed from it.

It does this by varying the duty cycle of its pulse width modulation (PWM) to match the load placed upon it. The wattage advertised on the box is simply the maximum power output the power supply can put out at any given time. Seems deceptively simple? Read on and you'll discover that it isn't.

Generally, what are the effects of such a myth? Consumers with limited budget believe that not only can they save a buck or two on a less powerful power supply, but they will also save money on electricity!

Yes, that would be like killing two birds with one stone, they thought. Unfortunately, all it did was help them end up with many dead computer parts when their power consumption exceed the power supply's ability to handle the load.

So, don't be stingy about your power supply. It's your PC's heart after all.
