Power delivery
The ASUS Prime B860M-A WiFi carries 7 Vcore power stages rated 80 A each in a teamed arrangement, under light heatsinks. Derating for the design and the cooling, our model puts it at roughly 417 W of sustained core power, which is enough for everything up to the Intel Core Ultra 9 285K at 245 W. That figure is published here rather than a marketing total because the phases that feed the SoC and the integrated graphics carry none of the CPU's core load.
What it throttles
Every LGA1851 processor in this database runs on the ASUS Prime B860M-A WiFi without throttling. Its power delivery is not the constraint on this platform, so pick your processor on price and core count and move on.
