I've been thinking about getting a Raspberry Pi to become a downloader/smart TV solution, given it's low price and low power consumption. Can anyone tell me how much power it will actually consume if plugged in and downloading via Ethernet? I don't understand all the power statistics that I've found on the Internet as they confuse me.

Can anyone tell me what the costs could be, or what the power consumption is compared to other electrical devices, such as a light bulb, router, homeplugs, etc?

Also, what's the normal power consumption for homeplugs and a normal router?

Well the Raspberry Pi is a 5 volt device drawing roughly half an amp, so thats about 2½ watts. And thats about 1/24 of a normal 60 watt filament bulb. Its comparable to a single Homeplug, which typically will draw about 3 watts. My router has a 12volt 1½amp power brick, so thats a maximum of 18 watts. It won't make very much difference whether the Pi is downloading over ethernet or not.

I have a Pi running 24/7 as a SqueezeServer (Logitech Media Server). It isn't making any noticable impact on my electricity bill (especially after the cold spring in the UK).

the power requirement for model A is very low. maybe 200mA. if you start powering peripherals with model B it can go up to 700mA.

but using the 200mA figure @5V you are looking at 1W. less than a tv on standby. 100th the power of a desktop.

about £1.50 a year.

That's great. I only planned on using it over night, or an hour or two on an evening, so it should be even less. Thanks for the replies.

I have been wondering about this as well, mainly to provide iPlayer, 4OD etc at my TV rather than at my desktop PC (which is not easily linked to the TV because of the distance).

I will be interested to hear how you get on if you decide to go for it, particularly in respect of programming it for those functions.

You don't have to program it for those functions. It runs Linux, just, you know, Google iPlayer. Install xmbc, whatever you would do with your computer.

I ran a series of tests on Model A and B raspberry Pi boards to test current usage and the Model B (one with ethernet) used 405mA when downloading a file via a wired network connection and 311mA while idle. When it was put in shutdown mode it used 111mA. The full test results are on http://briandorey.com/post/Raspberry...s-Model-B.aspx

Maybe except that, as yet, I know nothing about Linux, but interested to find out about it for this application.

I have enjoyed reading your website.

I know nothing about Linux either. I've only used it once or twice and didn't enjoy it, so didn't bother again.

I plan on using the default operating system that is recommended (Raspian, a derivative of Debian). I will install iPlayer, XMBC and a torrent client as a basic host downloader, such as jDownloader (or an alternative as jDownloader requires Java). I don't know when I will be buying this, as funds are low at the moment.
