Typically, gamers need powerful hardware to play the most difficult games available. A gaming laptop typically includes a quick processor, lots of RAM, a top-tier graphics card, and a high-resolution screen. You must ensure that your power supply can support the 200–300 watts that a gaming laptop generally consumes.
This is considerably less than a typical PC, which consumes more than 500 watts.
More energy-efficient parts and the fact that a gaming laptop is made to be used while connected into an outlet both contribute to the decreased power usage.
