The amount of power it consumes depends on your components and if you're using them at full power

Welcome to Linus Tech Tips!

 

The rating on a power supply is how much the power supply can give. If your PC uses 600W, a 1000W will have room to spare, but a 400W will not be enough.

 

1000W means how much power it can give to your PC's parts. If you're pulling all 1000W from it, it will be pulling more then 1000W from the wall.

 

If you could list us your specs then we can recommend you a power supply on here.

As above, a 650W power supply won't always draw 650W.

Watts is a measure of Joules per Second.

You don't need a 650W power supply for a 350W system.

A 1000W power supply that is say 80% efficient when delivering 1000W will pull 1250W from the wall, lose 250W as heat and deliver 1000W to the system.

 

What are your components? Budget? Location?
