Using UPS to power most networking equipment at home; does introducing a CAT6 connection via Powerline adapter open up risk of surges?

I'm a hobbyist at best when it comes to networking at home, and I currently have two rooms in my home that are joined by a powerline adapter. (these, if it makes much of a difference: https://goo.gl/FMD9LD)

Recently in the prime day sales, I picked up two UPSs. I knew I probably ought to have had these with my equipment much earlier on, but I took advantage of the cost savings. This is the model I picked up: https://goo.gl/dWsKzU

Up to this point in my research, the RJ45 ports on those UPSs do not support 1000Mbps speeds, and are only 10/100.

My office network "node" is based on an unmanaged gigabit switch which connects to the main router via the powerline adapter. On this switch, I have my primary computer, as well as a basic NAS.

My current concern, is that for these devices, even if the computer, NAS, switch, and related peripherals are plugged into the UPS, the fact that the switch is connected via CAT6 to the powerline adapter straight into the wall presents exposure to surges. Would this be the correct way of thinking?

I do have other doubts about the setup, i.e. if a poweroutage did occur, the powerline link would be severed anyway, because the powerline adapters would not have power. Eventually, I plan to run CAT6 through the wall to replace these. But I was interested in what risks I am open to in the short term.

TL;DR: Would CAT6 from a powerline adapter introduce risk of surges to devices powered via an UPS?
