Power delivery on AM5

The heaviest AM5 processor here is the AMD Ryzen 9 9950X3D at 225 W sustained, which is the number every board on this page is measured against. A board's socket tells you the chip will fit; it says nothing about whether the power stages behind that socket can feed it for ten minutes without heating up.

The useful question on AM5 is not which chipset to buy but how many Vcore power stages the specific board has and how big its heatsinks are. Two boards on the same chipset, twenty dollars apart, routinely differ by a factor of two in sustained core current, and that difference is what decides whether your processor holds its clocks.
