    Hey guys, how much power does a series 3 and tivo hD use? I have looked all over the internet but cannot find an answer.

    Its gotta be much better than a HTPC? My mac mini is 25 watt idle and 110 watt full CPU though, i use that for movies/pictures/music

    Thanks

    Another thread said 30 watts. I've been meaning to measure mine, but just haven't had the time, and opportunity to unplug it.

    I measured my series 3 at 37W. With the stock drive it may be slightly different.

    The TivoHD is a few watts less than the Series3, IIRC.

    I measured my S3 at 38 watts when I first got it. The series 2 it replaced was 28 watts.

    At 38 watts, and using the calculators at http://www.energyguide.com, my S3 would cost 7.8 cents per day, or $28.47 per year.

    I measured by S3 at 40W (39W in standby), and TIVO HD at 34W (32W in standby).

    Would be nice if Tivo had a *real* standby mode (a sleep or hibernate mode that only consumed a fraction of a watt), which it could be woken from when it needed to record something...

    The idea of the TiVo is that it is always recording something - ie. the 30 minute live buffer. As designed, it cannot go into sleep/hibernate mode since it is recording something 24/7.

    Due to a disagreement with pepco, I'm on a measure everything kick...

    Stock Tivo HD
    Reordering Season Passes: 38w
    Normal usage: 36w
    Tuned to two channels I don't receive: 34w
    Standby: 33w
    Avg over 24 hours, normal usage: 35.932w
    Current Cost: $3.78/Month

    Stock S3
    Reordering Season Passes: 40w
    Normal usage: 40w
    Tuned to two channels I don't receive: 39w
    Standby: 38w
    Avg over 24 hours, normal usage: 40.358w
    Current Cost: $4.41/Month

    Except I haven't measured the external esata drive yet...

    With a 1Tb WD drive my series 3 (648) measures 41 watts using "Kill A Watt". In Hartford i pay a total of $0.18/Kwh so my cost is about $64/year or $5.40/month for each Series 3.

    Just FYI, I measured my DirecTiVo power consumption with a Kill-A-Watt and it was about 40 watts. So a THD uses about the same power as the old technology. Not bad, considering how much more capable it is.

    I have my THD and TV on a UPS which indicates 32W of output when the THD is recording/playing back and the TV is off.

    For an interesting comparison, my Verizon standard definition non-DVR set top box is 500 watts, pretty much confirmed via Kill-o-watt at 478 watts. Interestingly enough, I can't measure a difference between on and off. I think off just turns off the front LED display.

    Wow, that's 4200 kWh/year. At $0.18/kWh, my rate, that's $756/year.

    That's power hog. What model is it?

    So that is the cost without ever turning on a TV?:)

    That's insane. Are you sure you aren't missing a decimal point? Or maybe including the TV? (And I mean a BIG TV?) I know it has a pass-through power port...

    I just looked in one of the online manuals for the Verizon STB's and the picture of the back of the unit lists the specs as 500W / 4A max. That's pretty scary. :eek:

    I've been moving my kill-a-watt around the house lately checking things out and it's going on one of the VZ set top boxes tonight! Even if it only consumes half of what what ACVTHREE reports, I can replace all of my STB's (4 of them) with Tivo HD's and the Tivo's will pay for themselves!!

    Edit: I think the 500W/4A max has to be for switched devices on the aux outlet. See this Motorola presentation that shows some power consumption levels: http://www.energystar.gov/ia/partne...nloads/settop_boxes/Motorola_Presentation.pdf Based on this data, the SD STB should use less than a Tivo.

    Assuming his numbers are correct, at 18c/kWh, it would pay for itself and lifetime service in one year. (YMMV)

    Can someone give a Kill-a-watt reading of a DVR model... I only pay 4c/KWH, but still that is way high!!! My PC doesn't even run that much with the old style monitor.

    WOW
