    They can run 24h-7d for years

    Edit
    If you mean how long would a computer run off the battery, then we have to know how much the computer draws in watts, and if the monitor is connected, what it's watts are.

    Typically it is only minutes to less than an hour with a monitor attached, and is really only meant to shut down the computer safely, in a power failure.

    So does this mean with the computer and monitor on at the same time is about 600 watts give or take.
    in normal operation with a supply 250-450 your power supply must be at least 225

    the electrican apprenticeship is a 4 year thing but with this class it nocks a year off but if you were to sponsor an apprenticeship who would you take some one off of the street or someone with this class even if it didn't take a year off.

    This is also a good link for specifications of the wattage and amperage of any cpu

    sorry but I don't have that cpu to test it.

    send me one and I will be happy to run the test on it for you.

    LOL

    How do you figure that??? The INTEL 3.2C uses more power than any CPU out there at the moment. Its also the hottest running CPU as well.

    um...this is interesting, nerver thought about how much power my computer uses :P

    I was wondering the same question so I did a little expirement on my own with a multimeter... I hooked it up to the power cord and checked to see what the current draw was. I tried to stress the computer as much as possible in order to get the maximum amount of power usage out of it. My system specs at the time were:

    EPoX 8RDA+ (nForce2)
    Barton 2500+ @ 3200+ (178x12.5@1.7vcore)
    2x512MB PC2700 @ 2.77v
    5 PCI slots used
    GF4 Ti4400
    WD 80GB 7200RPM 8MB Cache HDD
    CDRW
    DVD
    6 case fans + HSF
    2CC Lights

    What I did to ensure maximum power usage was turn on UD, play an MP3 to get the sound card in the mix, started a cd burning session at maximum speed, and ran Aquamark benchmark to get the video card active.

    The maximum amount of current draw was 2.1amps, the voltage at the time was fluctuating between 117-118 volts, which means the PC was using about 250 watts of power, which includes whatever inefficency that the PSU may have as well.

    This however does not include any other equiptment such as the monitor, powered speakers, cable modems, pritners, etc etc... Strictly the box itself.

    ballpark guess for the extreme gamming rig how many watts might this use (no speakers)
    this set up will perform just fine with a 500 watt generator, just be sure that you only have a ups plugged into the generator and a power strip plugged into the ups to run all the computer things.

    I have tested this setup and is great for when the power goes out

    great for you, look into a apprintice program.

    I am a certified electronic tech.

    works like a charm....you can test anything that plugs into 110. this topic comes up quite a bit [how much does it cost to run a computer] curiousity got the best of me so i bought one.

    .

    i run three xp2100 and on xp2500 24/7 ... the monitor is on the xp2500 about 4 to 5 hours a day. i bought a meter http://store.yahoo.com/ahernstore/p4400.html and it cost about $6.20 a month for each of the xp2100's havent check the xp2500 but will do so in case this topic comes up again.

    Sorry I have to butt in here and say this but I have done a LOT of research in this area. The only one of you who are remotely close is bailey.

    First of all, it does all depend on what cpu you are using and how many components you have in your system so the ONLY accurate way to find out is to hook up a watt meter. I have found that a typical pre-pentium 4 system will use between 60 and 90 watts depending on how much cpu is idle (the more idle the less watts being used). 17Inch CRT monitors tend to use 60-80 watts depending on how lit up the screen is (the whiter it is, the more watts being used). If you just turn on the CRT monitor, it sucks up about 300 watts for a second or two.

    Pentium 4 processors seem to use 80-100 watts alone on the tests I have done so MAYBE the whole tower would consume 10 watts max.

    Typically, if you leave your computer AND CRT on all the time with no standby or anything, your looking to spend about $20 a month on electricity per workstation. ($10 for comp, $10 for CRT)

    Plan on about 1000 watts, or perhaps a tad more to allow for peak loads. Both the monitor and the PSU has a very high surge current when first turned on.
