Do antminers use power when on but not connected to the internet?

Let's say the internet goes out for a few days. Will the antminers still be using significant power or would they barely be using any (just enough to power the fan and standby mode)

I think the miner will keep restarting(for antminer) if there is no internet connection so the miner will still continue to eat power.

You will need awesomeminer to automate the miner to turn it to sleep mode if there is no internet connection which will consume very little power.

Read the awesomeminer rules from here Rules - Detect mining issues and automate tasks.

Yes. Antminers run the boards with a certain amount of power even when not mining. The clocks are on as well, meaning it's pretty easy to find bad chips, but you also can't leave a board out of an antimer with +12 connected for a length of time otherwise it will get very very warm (BTDT with an S7 board)

If anyone's bored I can check the values but I recall it being about 200 watts per board.

Dragonmints do NOT do this, which makes finding bad chips a real pain in the ass.

Bitmain products not only keep using power, they use MORE power. Beware of overheating when you see all 3 pools "Dead".

Would be great if they had the power saving features any brand of cpu or gpu have nowdays, but they don't.

Do the test: disconnect the lan cable and observe the temperature values and fan speeds. Look at power usage too if you happen to have a kill-a-watt or such around.
