So, our TV has:
2 HDMI inputs
1 VGA input
1 F-connector for RF input
1 combined component/composite input

Things we want to connect to our TV:

1 computer (HDMI)
1 SNES (composite)
1 PS2 (component)
1 Wii (component)
1 PS3 (HDMI)
1 Wii u (HDMI)
1 Xbox 360 (HDMI)
1 Nintendo Switch (HDMI)

...you can see the problem here

Additionally, this gives us:

1 TV
1 SNES
1 PS2
1 Wii
1 X360
1 Wii U
1 Wii U gamepad charger
1 Nintendo Switch dock
1 PS3
(also 1 bug zapper because that was the best place to put it)

that all need to be plugged into a power outlet in the TV area. Of these, there are two that require extra space for a wall wart: the Switch dock and the SNES.

Currently, all of these are plugged into one of two power strips that are chained off each other. We just ordered today a 12-outlet power strip to hopefully help with this mess.

@Felthry you can get (unofficial) USB cables for the Wii U gamepad, I charge mine through the Switch Dock's USB 2 port :D

@Felthry also you technically have a redundant console there :P

@noiob Which one? If you're talking about the Wii and Wii U, the reason we have the Wii is for gamecube games because the gamecube component cable alone costs like four times as much as a wii

@Felthry you can play GC games on the Wii U and have HDMI out, you can probably also use other gamepads, I'm not super familiar with Nintendont (the GC loader) on the Wii U
