Automatic voltage regulator for computer set

Question

QUESTION: Is my AVR or small transformer consumes to my electric bill? even when I unplug my computer from it (even the AVR or transformer still left plugged to outlet). I'd be thankful to you.

ANSWER: AVR is what? The transformer and diode or rectifier set that may be in an enclosure on the power cord?

If so yes, even with no load, if you energize the transformer, it will consume power, not much but it will use power,

Answer

Oh OK there are a lot of different names for that device, Power Conditioner, Voltage Conditioner, but I know what you are talking about,

Yes it is using some power, how much I have no idea, they are rated in KVA, and while there is no "load" on the unit, it is running, electronics are energized, leds are working, so yes there is power being used, you would need an amp meter to measure just how much, I would think not much, but I have been surprised on other devices, just how much they do consume,

There are many plug in meters on the market, you plug the device into the meter, and it tells you over time what in KVA or actual power is used, they are fairly inexpensive, maybe $50.00 but you can measure your freezer, washer, anything you plug in, to give you an idea of the energy hogs in your home, great investment, I have one, I got the cheapest kind and wish I had not, for a few bucks more, the next model up, has a battery and stores the data, mine has to be read live, as once it is unplugged the data is gone, so get the one that holds the data, if you go that route, they used to call these SMART METERS, and were hard wired in the home, so that a home owner could pay attention to the more energy using devices and keep them off as much as possible,

But to your question yes it is using power, but without being able to measure it, how much I cannot tell you, again, I think not much, but it is always best to know exactly,

Why not put a mechanical timer on it? I am guessing you are disconnecting your PC so no problems with spikes and such, so that leaves your AVR there plugged in, you can get an easy adjustable mechanical timer, which uses NO POWER, and set it for when you are away, or if you are not using the pc, why not just unplug it all?

Hope that helps,
