    How much electric should a PC use if left on 24x7? I remember seeing a site somewhere that calculates consumption by ticking all its components, but I've lost the link. Does anyone know?

    how big is the power supply? say 400W PSU + 100w f0r monitor (and thats an over estimate)
    = 1 unit every 2 hours, 10 a day, whats a unit cost these days 5p?

    50p a day (with power saving more like 20p a day tops)

    It depends on the computer, the power supply rating is the maximum that the PS can supply, not necessarily its consumption.

    I have 2 PCs on constantly and both consume about 200 watts, but that will be more than most computers use. The main server has 11 hdds in it which will use about 10w each.

    I would expect an average computer to use between 70 and 120w with the monitor off, or about 2.5 units a day.

    Wyerd,

    Have you changed supplier at all ? We changed from British Gas Electric to Powergen Electric. Powergen supplied British Gas with a completely wrong reading and we ended up with a final bill of £310 from BG. Only just had it sorted and that has come down to a respectable £39.

    Same supplier since we moved in Aug '01 - Scottish & Southern. They've been round and wired another meter in parallel with the other. Looks like the only way to figure out what's eating it is by a process of elimination.

    Get in touch with your supplier, they can tell you exactly when/where you are using your power, it'll give you a clue anyway. have your bills always been this high or is this a 1 off?

    So are you running on the old or the new meter ? Or both !! Maybe they've added them together and multiplied by the house number :)

    Have you checked the readings on the bill with the readings on the meters ? They might have got them switched round.

    One thing to check is when you get home tonight, note the meter reading(s). Leave everything on as you would do and check the meter reading(s) again tomorrow night at the same time. This will give you a rough estimate on your daily usage. Then multiply that by 95 days for a quarterly bill and see if there is much of a difference.

    By the way, is your place gas or electric heated ? If it's electric, don't forget you'll have been working it overtime during winter.

    Richie.

    They've just wired another meter in to compare usage using both.

    We use LPG gas for heating and cooking using a duel fuel cooker. Electric oven.

    my parents had a new elec meter installed last year and then noticed a significant increase in consumption (may have been 50% but can't remember exactly).

    Still yet to hear ne outcome on it........

    The website u are after is possibly http://www.jscustompcs.com/power_supply/

    I've been measuring my electric usage after some massive bills, I'm using about 400 units a week, equating to £100+ a month bills.

    I have a couple of pc's that run 24/7, a server and music server, several amps and a few others pc's that were running all the time but have since been set to use power management, it only knocked about 3 or 4 units a week off. We have the usual gas water and heating, electric cooking, washing, dishwasher and tumble dryer, mainly low voltage lighting.

    I did a test with www.uswitch.com which compares suppliers against kwh used and Powergen came up £180 a year better than Scottish power which I was on. I'm in the process of changing now.

    I have a new style digital meter and did wonder if that might be the problem, its about £38 to have a meter tested. My next door neighbours have just had theres tested and the lady that came to check it said she only finds about 2 faulty meters a year (theres was fine). I haven't bothered to test mine yet.

    So do we. I'd prefer the old one as you can see the dial spin quicker when something starts eating into the supply.

    I used to run the Compaq PC 24/7, but for the last 2 months i've been turning it off at night, so it must be off for a good 10hrs, but has made no difference to the number of units used.

    As mentioned CRT monitors are the most energy expensive single computer items. Actual base units will not consume more than 80-100 watts depending on components regardless of the max wattage of the power supply.

    Little more then the cost of a light bulb on 24/7. If you have a CRT monitor at the least make it go into powersaving mode in a short space of time; either that or replace them with some LCD models using long term money saving as the excuse..;)
