It depends on what PC, but your power supply will normally say on the side of it. Most commonly is between 200-400 watts Power consumption is a combination of several things. The power listed on your power supply is the amount the power supply is capable of handling. The actual power consumption of the computer depends on what processes are being used, for example word processing will consume less power than heavy gaming. However, one can expect average computer use to consume 150-200W.
Most home mini PC's use a 100 to 150 watt power supply. There are larger home computers that use 200 to 400 watt power supplies. Some home computers are custom built and have power supplies from 400w to 2000w.
The average home computer will use about 150 to 200 watts for the PC plus the power needed for the monitor used.
An average Desktop's Wattage may be around 300-400 W, but high end Gaming computers may require up to 1500W at the most.
First let me define what is a KWh. If a machine consume 1000 watt and we use it for one hour it will consume one KWh, thousand watt consumption for one hour. An average Desktop Computer with 17 Inch CRT Monitor takes Roughly 300 watts means that continuous use of 3 hours consumes one KWh. If you are using a LCD Monitor then you can save lot of power. One KWh can run a Desktop for roughly 6 Hours.
In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.
Another category of user, called a power user, requires the capabilities of a powerful desktop computer, called a workstation.
A laptop.
Uninterruptible Power Supply. Its not a component of your computer rather a battery backup surge protector to keep your computer (or anything else for that matter) running in the event of a power outage.
Hibernate is a power mode that allows the computer to save an image of the desktop to the hard drive and enter a state of reduced power consumption to save energy.
Hybernation.
Hibernation
That means your computer has entered a state of Hibernation to conserve battery life. Very useful if you're working on something at work or school, and you want to resume the progress at home.
Hibernate.
It's relatively low price and low power consumption (in comparison with business computers and servers), ability to run a desktop environment for general use.
power consumption heat production
The power consumption just depends on your PC configuration. For a decent home user desktop it is 400W for your CPU plus the Power required by your Monitor & Speakers & any other device. The Power consumption increases with increase in hardware inside your cabinet.

If the same processor is installed on both a laptop and a desktop, then the each of the processors will use the same amount of power. But, usually, in computer companies don't put more powerful desktop processors into their laptops, they usually use a less powerful processor, which would less power than the average desktop processor.
they generally use all the same components as in a desktop pc (hard drive, RAM, optical drive etc.) but there are "mobile versions" of them for laptops that are often different in their size and power consumption.
