I have the 100Mbps 16 port unmanaged version of these Zyxel
ones. It just connects to mains, no separate PSU. It is quite small and for a while it lived under my ADSL router.
I bought it some time ago. I now wish I had bought the 1Gbps version but at the time I did not have anything that ran at 1Gbps and my ADSL broadband connection was good for maybe 1.2Mbps. I would only buy a managed switch if it did not cost much more.
If you want PoE perhaps for a camera you can just add another PoE switch. There are various options.
