Unlike the 2013 model, which topped out at 165 W, this PSU dishes out 289 W of power (1.5 A @ 4.8 V +23.5 A @ 12 V).

For comparison purposes, we lined up the PSU from the PS4 Pro (left) and the original PS4 (right). While there's only an 74.2 g difference between the two units, the requisite heat pipe and fan add a bit more bulk to the Pro to wick away excess heat generated by the additional graphics power.
