So I'm finding it a little difficult to figure out how I should be powering my setup. I'll have Waveshares IO board here: https://www.amazon.com/gp/product/B08VJBGD1Q/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 along with the Compute Module 4 (8GB) and I'd like to have the capability of fully powering one of those PoE ports and at least 1 USB port.... plus the Pi of course. So assuming both the PoE and USB device are drawing power at the max, what does that result in? I started reading about voltage, amperage etc and realized I don't want to blow anything up (Pi 4s are rare and very expensive these days) because of my misunderstanding so I tried looking up some power supply calculators but all seem to be for PC desktops. I'm pretty confident that this: https://www.waveshare.com/ord-psu-12v2a-5.5-2.1.htm is enough, but I wanted to check with you Pi folks first. That would provide enough power, right? Please feel free to link any good calculator sites out there as well, already got a nice collection for my new Pi 4 rolling :)
