CPU power
360 W
Sufficient · 1.4x
Wired for about 360 W, enough for every processor on this socket including the top Core Ultra 9 chips at their 250 W ceiling, without a lot left over. The figure comes from its 2x5+1+1+1+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.
