CPU power
576 W
Overbuilt · 2.5x
Wired for about 576 W, roughly 2.5x the 230 W that the top Ryzen 9 chips pull, so nothing on this socket will run it short of power. The figure comes from its 2x6+2+1 power-stage (VRM) layout and 8+8 EPS connectors. It is a rating of what the board is built to deliver, not a measurement, so treat it as headroom rather than a guarantee.
