You've decided to build a new gaming computer and are researching which power supply to buy. which component in a high-end gaming computer is likely to draw the most power? what factor in a power supply do you need to consider to make sure this component has enough wattage? \

It is usually the GPU and the CPU in that order. The most you really need to consider is looking at the specs of the parts and add up the wattage. Add 100 Watts to it to be safe and it should be fine. Just purchase a PSU with a 100 watt extra leeway for the pc, which is a negligable price difference.

i don't understand. explain it clearly

e/c, where e is its total energy
