AMD Ryzen 9 3900X on the Gigabyte B550 Aorus Elite AX V2
The AMD Ryzen 9 3900X holds its clocks on the Gigabyte B550 Aorus Elite AX V2: the board's 12 Vcore stages carry about 574 W and the processor asks for 140 W in a sustained all-core load, which is 24 % of capacity and an estimated 54 °C at the VRM.

Power delivery
This pairing is not close to any limit. 140 W against 574 W of capacity leaves the Gigabyte B550 Aorus Elite AX V2 running its stages at 24 % load, and our model puts the VRM at 54 °C in a closed case. Nothing about the AMD Ryzen 9 3900X pushes this board into the region where clocks start dropping.
The Gigabyte B550 Aorus Elite AX V2 carries 12 Vcore power stages rated 50 A each, teamed in pairs off a shared controller channel, with a solid block across both banks. That works out to about 574 W of sustained core power once the design and the cooling are accounted for, which is the number the AMD Ryzen 9 3900X's 140 W is measured against.
Buy it on the rest of the specification rather than on power delivery, because at 24 % of capacity the VRM has stopped being the interesting variable. Count the M.2 slots you need, check the rear ports against what you actually plug in, and let the Gigabyte B550 Aorus Elite AX V2's 12 stages get on with it.
