You don't need a tv for the PS4, a Vita will do.
You can run a sneaky extension cord from your neighbour'a house. So the power consumption conparison is redundant.
The switch has an additional cost of vaginal rejuvenation for non-virgins, because that is a requirement of playing Nintendo games.
Don't forget to add the expense of maintaining all the friendships of the people that you'd like to play online with. Birthday and Christmas gifts, eating out, alcohol etc.
And lastly, you'll need to add the cost of therapy from all the abuse you receive from chatting online with the PS4 elites and Xbone dudebros
