    Power Meter / Watt Monitor - Where to buy?

    I've heard a few people mention about testing their PC with a power meter to find out how many Watts the PC is using... I've heard of these power meters that you plug in between the socket and the appliance on TV shows, and most recently on the BBC Breakfast show, they said that B&Q sell them for £9.99, but I went to 2 B&Qs local to me, and I couldn't find it: When I asked about it, they didn't even know what I was talking about! I know maplin sell 1, but it's a stupid price at £25!

    I saw on some forums that B&Q had them for £4.98.... Strange - I was planning on checking B&Q out tommorrow.

    ebay has them for around £14 delivered. Search for Energy Monitor
    I saw them in Maplin and yup they are quite expensive although they have been on offer once or twice before for around £10-£15.
    I think B&Q, homebase or even Woolies might have them. Also try Robert Dyas, they tend to sell all sorts of household stuff.

    I got mine from Maplin for £9.99. Seems to be £14.99 now.

    Remember to check the accuracy by testing a standard light bulb with it.

    Was your accurate with a lightbulb?

    I bought mine from Maplin. I don't use it long term; I was just interested in seeing how much power my equipment drew - especially my computer. I just plugged in a lamp with a 50W rated bulb and got the following: ~244 Volts @ 49.8Hz drawing 55W.

    They won't be 100% accurate since they're only budget devices but they're good nonetheless. Just don't show the results to whoever pays the bills! lol

    Thank you for the tips on how to test the meter. I need to test the one I bought from Lidl (it's been gathering dust as it gave weird results when I plugged it in to a surge protector).

    The idea of a tesco value keyboard and mouse is scary!

    ...even moreso when you know that the value range is normally the old version used for the regular range, which is normally the old version for the 'finest' range. Which means somewhere there may well be a "Tesco finest keyboard and mouse" o.O

    I have two of these monitors, one was a tenner and is rubbish, the other is the Maplin one which is the one I actually use. I got mine on a half price offer for 12-50.

    Check that the monitor has a "power factor" indicator. The cheapest ones have no concept of power phase, and assume that the load is resistive. That is fine for lightbulbs, but not for anything with a modern PSU in it.

    I bought some cheapo £7 speakers from Tesco, and they are superb for the money - they sound good, and best of all are weighty so don't fall off the desk every time the cables get dragged. Many other cheap standard PC speakers are just so lightweight and I really don't want to spend more than a tenner to hear my PC beep at me or play the occasional youtube video
