The new power supply is rated for 12 V at 1.083 A. This is a modest bump up from the 0.917 A power supply in the Apple TV 4th Generation.

Again taking a design lead from its older sibling, the Apple TV 4K eschews internal wiring between the power supply and logic board.

The use of conductive posts in lieu of wiring probably saves internal real estate, and it eliminates the possibility of pinched or bent wires during assembly.
