CPU power

288 W

Sufficient · 1.2x

Wired for about 288 W, enough for every processor on this socket including the top Ryzen 9 chips at their 230 W ceiling, without a lot left over. The figure comes from its 2x4+2+1 power-stage (VRM) layout and 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.
