Many people have wondered how much power a TiVoHD consumes, as did I, so I measured it.

In 1720 hours (71.7 days) the TiVo consumed 33.7 kWh, so an average of 19.6 Watts.

In a year it would use about 172 kWh, at 20c/kWh that would be $34.

That's actually really interesting, I wonder what it's like compared to other hdd recorders.

It appears TIVO doesn't have a real standby mode, it just turns off the video output only!

Correct. It is always recording from both tuners, even in standby mode AFAIK, though I have never tested that. We never use standby mode.

FYI 'peak' power draw was 54W, probably during bootup I would guess.

Thanks for this info. Very interesting. Would be interesting to see how this stacks up against other players. Doesn't seem like a lot of power usage for a year.

Thanks for that - just what I wanted to know as, I mentioned in another post, the TiVo manual doesn't give the figure. That's lower than what I've read for the US model (c. 30w), and low enough not to make me feel too bad about having a PVR that is on continuously.

Trouble is it's all cumulative. Neither the Tivo, or any other kit alone, may seem that significant. But when you add all the devices you may have continually sipping power (Tivo, Sky box, DVD recorder) then the collective draw can start to get up there.

Maybe less, as it only has two tuners, while the sky has 3. I wonder how it stacks up against a media pc.

Yes it sure can. When we are away on holiday we still 'use' 6 to 7kWh per day, which is 250-300W! I would turn the whole house off, but then my wife would miss some of her precious reality TV shows, and the neighbor wouldn't be able to see when feeding the cat at night. EDIT: and, we would have to empty the fridge...

Know the feeling. We went away on holiday at the beginning of the year. Having recently moved to Powershop I was in a power-saving mode so suggested to my wife we turn the power off at the mains while we were away. I then remembered the alarm wouldn't work; it took her brains to remind me the fridge and freezer may be of more significance! The alternative I went with was turning off every plug in the house bar the essentials.

At least appliances are generally becoming more energy efficient with each generation, both in stand-by and while in use. And power consumption isn't generally enough to sway me for or against a purchase - I'd still choose plasma over LCD any day.

Do you know what those appliances were, and how much each was using. I suspect fridges and freezers use alot.

No, I haven't worked that out yet. They would include fridge/freezer, TiVo x2, Dreambox, network switch, router, modem, clock radio x2, microwave, solar hot water pump. I agree re fridge. Things on standby don't use much these days - eg heatpump, xbox, TV, PC.

I brought a power use meters from Dicksmiths a couple of weeks ago. Generally use was as expected including as I had suspected the Telstraclear STB which uses ~9w regardless of it being in standby or on. The one unpleasant surprise was the Velodyne sub which uses 15w when on, standby or off (of course more when in use) :(
Someone asked how the power of the Tivo compares to a HTPC. Unfortunately I do not think you can say as it comes down to what the hardware is which low power system at one end and a gaming type system at the other and of course what it is set to for instance our HTPC sleeps when not in use but some are left on all the time and I am sure some are shut down.

Just googled it ..

According to that post, MySky HDi uses 28W when on, 26W in standby. 

So if TiVo is using only 19W, is not only cheaper in terms of subscription, it saves you about 20% on power usage as well. Money Mouth
