At 600 watts running continuously wouldn’t that be 432 kWh a month?

Assuming you didn’t mean you were running your gaming computer as the server.

At 100 watts that comes out to 72 kWh, in CT where I live rates are waaaay higher then what I calculate your rate to be (around 2.5 cents per kWh)

For me a 100 watt server is about ~$22 a month to run.

Are you sure your paying 2.5 cents per kWh?
