Question

Your customer wants to build a new computer and needs to make sure he orders the correct power supply for his machine. What should you tell him to check to make sure he orders the correct power supply? (Select all that apply.)

Answer 1

The correct power supply can be selected by calculating the total power requirement by different components/devices in computer.

Step-by-step explanation:

The computer have different components that have their own power requirements to work efficiently. These components/devices includes:

1. No of hard Drives, as each drive consumes power
2. CD/DVD ROM, If any
3. Graphic card/GPU
4. Random Access Memory (RAM)
5. CPU

These all components consume power at different rating. First of all we calculate the power required by all components, then add that power to find the total Power. According to that requirement of power, the power supply will be ordered.
