How much does a ac-dc converter consume?

Hello everyone. I am duped on how power supplies work as I am not an electrical engineering but rather a hobbyist or a DIYer. I a, looking for cooling solutions and discovered the inverter technology. If I understood it correctly, the compressor is run by DC, running at variable speed for which whatever the system needs. 
    If I want to assemble a phase change system, using a DC compressor and I have a AC power source (residential) and convert it using a AC-DC converter, I do not know how much electricity I am consuming.

This is what I am thinking, and these are just examples for simplification. Supposedly that I use a Switching Mode Power supply,rated 10A, connect it to 220V AC the watt consumed is 2,200W. If I connect it to a load, DC, for example it outputs 12V, and the load uses 5A, so that is equal to 60W..
My question is, how much electricity I am consuming, and consequently have to pay? Is it 2,200W or 60W? 

Hi,

So here is something that might explain what a "SMPS()":http://bit.ly/2eDjifa does. Now if you understood it, it would tell you what? I think what you would want to determine is what is the power efficiency and the maximum power transfer of the supply.

Firstly, a SMPS doesn't consume power to any large extent, the load does, which is why they are used.
So as a first approximation, it is a simply a matter of calculating the power in the load, and figuring out the kW hours knowing the volts on the load, and the current.
The rating you mention, the maximum load current the unit can supply, relates to thermal stress and current limits in the components within the SMPS.
If you want to delve into the issue in more depth, there are usually efficiency versus load power figures (or even graphs) supplied by the SMPS manufacturer, they will typically be between 70-90%.
This means that 10-30% of the power will be dissipated in the SMPS, the balance in the load, obviously the kWhours are greater to that extent.
Additionally, there is an issue around Power Factor, real power to apparent power,,
cheers,

Thank you for the answer. This is also the reason why I chose a SMPS because it is more effecient than a linear type power supply. So to answer my own question, the power that I will ne consuming is load dependent.
