    So I ran across the article below which says that "a set-top cable box with a digital recorder can consume as much as 35 watts of power, costing about $8 a month." I was just wondering if anyone knows off hand how much electricity a TiVo Roamio Plus consumes/costs to run in comparison.

    ~20w for 6 tuner model. 9w for each mini.

    I am probably using 120w right now between my htpc and 360 extender.

    not only are they still maybe giant energy hogs, but they also continue to be giant pieces of junk in terms of usability. I hadn't used an Xfinity based box in YEARS. It was junk then. I recently was at a family member's house who has a newer X1 DVR box. Looks like nothing has changed as its STILL a giant piece of junk :thumbsdown: :p

    it also depends on your electrcity cost. Mine is around 11.5 cents per kWh. A 35 watt, 24/7, device costs under $3 a month for me.

    Same here. If you're paying $8/month for that much power it's because of poor planning and/or political choices (e.g., NIMBY) that were made in your region.

    CT is the highest in the CONUS at around 18 cents a kwh. And I'd much rather have our grid than just about anyone else's. We have 40% clean, green, low-carbon nuclear power, and the remainder of our grid is less dirty than most others, with a relatively high renewable requirement (not sure exactly what it's up to at this point). I don't think we have any coal left.

    I live in West Hartford CT and my biggest CL&P bill (about $150) was at 15.8 cents a Kwh, my smallest bill was $116 at about 16.5 cents a Kwh, I guess with a fixed $16 charge before you use your first Kwh you can get to 18 cents a Kwh with a low use of power. The incremental cost per Kwh for me is 14.2 cents per Kwh, that what I use when trying to find out what any hardware is going to cost me in electric cost. I had an older flat screen HDTV that used 25 watts when off, that cost me $2.5 per month, the TV is now in a guest room and not plug in unless I have people using that room.

    Just did the calculation: $8/mo for 35W 24/7 is 31 cents per kWh. :eek:

    So it costs me about $3 per month to run the box with all the features? Seems like a bargain to me. I can turn the AC off for a couple of hours in a month and save that.

    Then there is the Cisco (Scientific Atlanta) TA which runs so hot I suspect it uses more power than a TiVo, especially the later model TiVos.

    Interesting. I had noted that the **input** rating of the power supply is 1.2 A (at 120 V), which is well over 100 W. Presumably this is a peak rating unless the unit is very inefficient. All I can say is the TA sure produces a lot of heat for a 15 W device!

    The cable and satellite television industry agreed to reduce the power consumption, but the article states that "...the agreement has no penalties for noncompliance." It sounds like many of the companies may ignore the agreement. It may be up to the customers to force the companies to do something about it or to shut the box off (disconnect the power) when not being used.

    TiVo uses less power than many of the boxes from the cable companies, but a significant portion of the problem is the nearly constant full power usage all the time and the multiplication of this by all of the users that keep their boxes on all the time. The cost of having a DVR on all the time is more than the kWh used by the DVR. A DVR is a heater, and it will potentially slightly increase your cooling costs if you use an air conditioner (unless you are doing something unique to avoid the increase). Also, a gateway or modem and router are needed by the box that are also often left on all the time. Tivo Inc. should also do something about the constant nearly full power usage such as having the box go into a very low power state at night. Also, there is no need to have six tuners buffering all the time. According to the post at the link below, there is also a reason not related to power savings to not have all tuners buffer all the time.

    I got slammed on this Forum for telling people that I have one of my TiVos on a timer. The timer turns off the TiVo at about 4:30am and turn it back on at about 5Pm as I do not record anything in that time slot, I think it will reduce the total power and increase the hard drive life, has worked for me and the updates still will get put in as the re-boot for updates takes place at 2am and don't last more than 2.5 hours.

    Power cycles and heat are hard drive killers.

    It's your box. You can do what you want with it. Although personally I don't have that option. Since I have recordings going on every day and almost every hour of the day. I typically have six concurrent recordings six days a week a t some point.

    Plus the power usage of the Roamios are much lower. There are other things I can do to reduce my power usage before I turn off my TiVos. Like I could have my game systems all shut down instead of use standby. My two XBOnes use 12 to 16 watts each while my PS4 uses around 9 watts. Then I have my external drive cases for my unRAID setups. They draw a couple dozen watts just sitting there, but it makes it easier for me since they automatically come on when I hit the power switch on each main unRAID box.

    I did recently switch all my CFL bulbs out to LED(47 bulbs) which does save me on a lot of electricity and less heat output(I'm using around 60% to 70% less electricity with my LED lights). I have noticed that my A/C needs to run less now to get to the set temperature since I don't have the CFL bulbs putting out 130F temps. The LED bulbs are only putting out around 90F to 95F.

    Does that apply to SoCal. Our rates are tiered. At the beginning of the month I pay 13 cents, then 16 cents, then 30 cents and finally 33 cents for each KW in the top tier. They jigger around the number of KWH needed to reach a tier depending on the season so it is very hard to predict exactly. My average for the month, gotten by dividing my full bill by the total KWHs for the month was just under 18 cents a KWH.

    I don't know about poor planning and political choices, though both are likely true. I think we are helping Southern California Edison pay for decommissioning of nuclear plants among other things.

    We have more clean green nuclear power here in Illinois than anywhere else. ComEd soaked the ratepayers that the insane investment would result in "power too cheap to meter." Then pushed a deal through the state legislature to move the plants to their parent company and make local ratepayers pay "competitive market rates."

    So you get the power from our "too cheap to meter" nuke plants we built and pay what we pay.

    CL&P in CT is only 18% clean as you say or renewable as most people say, unless your referring to nuclear power as clean. You can get 100% renewable as an option if you want to pay an extra $0.025 per Kwh about 25% more than CL&P is charging per Kwh (10 cents vs 12.5 cents) The delivery rate is fixed and is addition to your Kwh charge, it amounts to about 6 cents per Kwh for the average home.
