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.
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.
The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts.The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts. To estimate: 10 kVA UPS ≈ 8000 watts (assuming 0.8 power factor) If each computer uses 400 watts: 8000 ÷ 400 = 20 computers So, a 10 kVA UPS can support around 18 to 20 standard computers for a limited time, depending on the load, battery condition, and runtime required.
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.
The average power consumption of a computer monitor is typically around 30-60 watts.
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.
Hibernation
Hybernation.
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.
The average computer monitor power consumption is around 30-60 watts. To optimize for energy efficiency, you can adjust the brightness settings, use a power-saving mode, and turn off the monitor when not in use.
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.

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.

The average power consumption of an LCD monitor is typically around 25-30 watts.
