Electricity usage.

[Desperate D]

Can anyone tell me what is the approximate usage of current for a computer both fully logged-on and on standby? Also the same for a 32" TV

no ... but you can look

the label on the back will give you the power rating

a pc (crt or lcd) ... 120 - 500+ watts depending on all sorts of factors - big games machines eat lekky.
and it's not going to be on a label either ... but the PSU rating will give an idea if it's a guzzler (320w - 1Kw are common)

your telly could be 10-180+ watt - lcd plasma
depending on all sorts of factors
the only way to tell is look at the label

one of these will tell you exactly

Thank you ACtheTROLL

I had already looked on both appliances for power rating without success. I am 87 and a total fool where electricity ratings are concerned. I am also not very mobile. However after searching the backs of both items and crawling round the floor with a magnifying glass,
all I can find is a rating of 50/60 khz on both TV and power unit of pc. No wattage whatever.
I may well get one of Maplin appliances, though I have found an article on web giving guidance on which domestic items are the power guzzlers and I believe the heaviest in my case are the fridge-freezer and the other chest freezer.
Thank you for your help and advice anyway - I'll continue my research.

You could buy something like this from Maplin � and measure the power consumption yourself:-

I would not recommend using ACtheTROLL�s method to give a reliable indication of energy usage (rating plate figures). Most manufacturers list a peak power draw on their products, not the average.

I have a similar device (as above), currently monitoring the power consumption of my PC system, which includes a printer & scanner (on standby), together with cable modem etc. The PC is rated at 300W and I have a 22 inch LCD monitor, all powered via the monitoring device � which is indicating a power draw of less than 160W.

Thanks Hymie -that's a great help. My PC is on for about 12 hours a day and I only switch the printer on when I want to use it, which is not often, so I reckon I'm using about 2 units per day.

[Hymie]

I would agree with your analysis, and at about 10p per unit � having your computer on for 12 hours is costing you around 20p in electricity.

However if you have an old-fashioned CRT rather than LCD display, your power consumption may be costing you up to 30p per 12 hours � even a fairly small CTR will be consuming around 100W, continuously.
