enough amps?

My project is running off of a stock Wii power supply (12v, 3.7A) and I was wondering if that would be enough to run the Wii plus a few other things attached. What it’s supposed to power: 7inch screen, 12v fan 60mm, Usb drive, Sd card, Wii while playing games, Wii to hdmi, And maybe an hdmi...
