How many watts does a computer needs to work?

Answer 1

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?

Answer 2

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.

Answer 3

That depends on what computer you have. And what you are using the computer for.

Answer 4

Depending on the size/specification of the computer it could need anywhere between 100 and 800 watts.

Answer 5

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.

Answer 6

That varies widely from computer to computer.

Answer 7

0.5 watts it take
