Hi @halpac,

All power information is included in the product information on the TP Link Web site so have a look there to compare power requirements.

The oc200 uses a 5V 1À power supply, so the controller's power consumption would not exceed 5 watts.  True consumption may be a little higher due to power loss converting from AC to DC.

If ~5w is too much, you don't even need the controller if you get an unmanaged switch or configure your devices individually using their web UI.

  @D-C Thank you very much for the answer.

1) For the OC200, is 5W the maximum power consumption or does it consistently consume 5W during operation?

2) Similar question; I've read switches specifications and the only relevant data I have found is "Max Power Consumption". But max should be the highest possible, how do I know for an average use or when I am not using any device connected to the switch how much is the consumption?

3) I have compared two switches max power consumption and I've found there is an huge difference in power consumption. The SG2210XMP-M2  has 180.1 W max power consumption while the SG2008 has 6.4 W max power consumption. How can such a large difference in power usage exist for switches of similar size?

5W would be the maximum.  I assume it's actually lower because the engineers wouldn't want zero tolerance on the power, but I've never tried to measured mine.

I haven't seen any documented idle power consumption or estimated averages for these types of devices.  I've only seen this type of info on TVs or other large appliances.  Average use is going to be different for everyone, so max is probably the only value that reliably means anything.

Power consumption is based on all the features and not just the number of ports.  Have a look at the specs in more detail and you'll see that these devices are nothing alike.  The sg2008 is about the most basic Omada switch you can get.  The sg2210xmp-m2 has a 160W power budget for POE devices and there are other power consuming upgrades as well like having 2.5GB ports and SFP+ ports.
