I was just wondering how much power does it use?
I've got a CRT, plus my computer which uses, according to this (http://www.extreme.outervision.com/psucalculatorlite.jsp) uses 285W of power.

How much would it cost in dollars and cents terms in both these scenarios:
Downloading stuff with the crt on standby.

Per hour would be preferable.
I did use google but did not come up with and dollars and cents terms.

Thanks guys.

Find out how much power CRT uses. Documentation will tell you that.
Take the power figures (with or without CRT as the case may be) and multiply by the hours they are running. Divide by 1000 and then look at your powerbill for the cost of a unit. here in timaru about $0.14. So example for 285W on for 5 hours. 285 x 5 = 1425. 1425/1000 = 1.425 * .14 ~ 20cents.

I think

Try Googling for "pc Kill-A-Watt" and you might find a pc with similar specs to yours that has been measured for actual load with a plug in Kill-A-Watt or similar meter. Then do the timaru2007 calculations. Your PC case will probably be using around 120-150W.
