I'd bet the power supply is just rated at 185W. No fucking way is a router actually drawing that much power.

Carrier grade routers do. https://www.juniper.net/us/en/products/routers/mx-series/mx304-universal-routing-platform/specs.html https://www.juniper.net/us/en/products/routers/mx-series/mx3... Random example from a search. According to a calculator I plugged a few values in, it's 2880 watts, but not sure I computed it correctly.

  P=I * E 2880w = 60A * 48VDC It checks out.

  I mean this is hacker news, but no one is talking about that beast. "My vehicle has 3000 horsepower." "That doesn't sound right." "Ackshually trains do. Maybe he drives a train." "..."

    Man I hate to be that guy... but I do in fact have a blade chassis in my basement that can pull 6kW. I didn't even blink at 185W for a router, one of my switches can pull 125-200W alone. Some of us really do have that stuff just sitting around.

      The post clearly says ISP provided. So sure you have that, but you're doing the train thing. They weren't talking about that class of device.

My fairly beefy laptop's PSU is rated at 135 W. It includes an entire GPU. My own router's PSU is rated at 36 W, for comparison.

I've seen people running routers on beefy machines that can certainly pull down hundreds of watts. Even more if it's an older machine.

You are correct. The input on the wall wart is 100-120vac 1.5a (150watt to 180watt) but the output is only 12.0vdc 4.6a: 55.2 watts The "xFi Advanced Gateway (XB7)" router is definitely warm to somewhat hot on the outside. The AC here varies from 118vac to as high as 126vac (maximum rating.) Right now it's at 122vac. I think my 185 watt number might have been 123.3vac x 1.5a, or maybe it was the previous "xFi Advanced Gateway (XB6)" which was also a chimney. I am not an ISP. We work remotely — there is no fiber here yet.

  Yeah so that means at most it can pull 1.5A. So realistically it probably runs at like 20W or likely even less.
