That depends on many, many things. First, you'll need to list the wattage required for all components. Then you'll need a PSU (power supply unit) that can manage that much wattage. If it's a typical desktop, you'll need at least a 500-watt PSU. As for lasting 1 hour, I'm not sure. Hook it up to a generator maybe?
This is a question that really cannot be answered here as there is no one answer and it depends on the exact computer. Computers in general use a wide wattage range. Many of the old home computers of the 1980's used only a couple of watts at most, and that was just for the computer portion. The monitors used anywhere from 70-500 watts of house current. Early IBM PCs had 150 watt or so power supplies. Today 450 watts is a common size, but there are power supplies that produce over a kilowatt of DC current for use in gaming systems and supercomputers.
If you want to know how big your power supply is, your best bet is to look on the PC's power supply, or on the bottom of the laptop.
That depends on what computer you have. And what you are using the computer for.
Depending on the size/specification of the computer it could need anywhere between 100 and 800 watts.
The average computer uses about 12 watts per hour. In other words, you can run a computer for eight-three hours on just ONE kilowatt of electricity.
That varies widely from computer to computer.
0.5 watts it take
it's volts and not watts that the question needs to be asking. But the PS3 slim, which uses the least power needs more than 220 watts and it also needs power for the TV
about 200 watts if you are not involved in heavy work like sophisticated game
You need to know what kind of voltage all your computer parts work at. There's not really a general Watt power supply that you should look for.
Conversion from gas to electric should be 750 watts/hp So 7.5*750=5625 watts These are running watts so that is a bare minimum. Depending on the application it needs much more starting watts (up to 3 times for a compressor). Generator should be no less than 8000 watts, maybe more if you work it hard.
The certification that one needs to work at a computer help desk is lots of knowledge on computers and how they work. You would also need to know how to fix common computer problems.
A computer needs at least a BIOS and an Operating System.
Sandisk have a range of products many of which will work on a Macintosh computer.
Work and Time; Power = Work/Time
Any computer needs electricity to work. Laptop computers have an internal battery that powers the computer when you are away from your work desk. If you are return to your work desk or the battery is running out of charge you can still attach the laptop computer to mains electricity.
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.

There are many types of work that can be completed on a computer, including payroll. Research for projects and hiring can also be done on a computer.
