Advantages of power supply

Answer 1

Advantages

Pollution can be kept away from cities and large power stations can be built, which are more efficient.

Power can be diverted to where it is needed, if there is high demand or a breakdown.

Surplus power can be used to pump water up into reservoirs to be used to generate hydroelectric power when there is a peak in demand.

Disadvantages

Some power is wasted heating the cables.

Overhead power cables and their supporting towers are an eyesore in some places. If underground cables have to be used, they are much more expensive.

Smaller local electricity generating projects, such as wind turbines and/or panels of solar cells, are unreliable compared to a national grid fed by major fixed power generating stations.

Answer 2

A power supply provides a stable source of electrical energy to power electronic devices, ensuring they operate reliably. It protects devices from voltage fluctuations and electrical surges, which can prevent damage and extend their lifespan. Additionally, a power supply can improve energy efficiency and reduce electricity costs by supplying only the necessary power to devices.

Answer 3

Capabilities of basic computer operation. Can't power the motherboard, GPU, CPU, etc. without a power supply.
