I think it was 66~ watts for my Layer 3 8 port 10Gb switch, and Router in use.

they do make some good hardware, just this one they cheaped out on and used 16MB’s of Storage, it really hobbled the device.

The one i linked is both a router and or switch, you can get cheap switches for like $300 that do really well.

many people just buy junk like this https://www.amazon.com/Mikrotik-Router-Switch-CRS305-CRS305-1G-4S/dp/B08437RDM1 it’s cheaper in the long run.

You will need a good 10Gb nic, I have been using Intel nic’s if you use a Intrusion Prevention System that can eat away at the CPU, also more RAM helps like 8GB’s or more for IPS, I use 16GB’s for IPS + ZFS and a nice Switch can help a lot as it can do DNS and the works, more or less i use a firewall box to a Switch and use a Layer 3 Switch for routing, some can do 20+Gb’s routing.

this is what i do, i look it up on the firmware selector and go from there.
