Whatโs the biggest power supply myth youโve run into on the shop floor?
โ Myth: A higher wattage power supply always consumes more electricity.
โ
๏ธ Fact: A power supplyโs wattage rating indicates its maximum rated output capacity, not how much power it continuously consumes.
For example, a 500W power supply does not automatically draw 500W from the input when connected to a 300W load. Actual input power depends primarily on the active load and the power supplyโs efficiency.
Understanding the difference between rated output capacity and actual input power is key to selecting the right power supply for your application.
