Sorry! Got confused with units, this is the real answer!
Computer 350 ~ 500W,

17″ TFT screen about 25W an hour. A CRT of the same size will probably be around 50W, though I am not too sure on that.

With the computer though the power consumption is based on the load, i.e how much hardware is inside and (To a lesser extent) how mcuh work the machine is doing. 300W should be a resonable number to use.
