Lookin to buy a light and have a question about power consumption

[antic]

This may seem kind of silly but I was thinking that my two cpu's both have 600w power supplies and they are on all the time. Do they pull the same kind of power a 1kw lamp would?
Something that seems to good to be true usually is. Turning off my p.c.'s to avoid a power spike just seems to easy.
So do you guys think that they would be similar if not the same?

You should go and buy one of those power usage meters. It will tell you straigh up what your PC is using.

I have a 500watt power supply on my PC and my power usuage meter is currently showing 170 Watts. I'm also playing music through my 70Watt monitor speakers and I have a mixer plugged in. I reakon if you booted up some games the usuage would go up a fair bit.
