Power delivery
The ASUS TUF Gaming B850-Plus WiFi carries 14 Vcore power stages rated 80 A each in a doubled arrangement, under medium heatsinks. Derating for the design and the cooling, our model puts it at roughly 1134 W of sustained core power, which is enough for everything up to the AMD Ryzen 9 9950X3D at 225 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 AM5 processor in this database runs on the ASUS TUF Gaming B850-Plus 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.
