AMD · Zen 3 V-Cache · AM4
The AMD Ryzen 7 5800X3D is a 8-core Zen 3 V-Cache processor for the AM4 socket, rated 105 W with a 142 W boost ceiling. What matters for a motherboard is the middle figure: it settles at about 120 W in a sustained all-core load, which is a moderate load for a VRM.

Every AM4 board in this database runs the AMD Ryzen 7 5800X3D without throttling it. At 120 W sustained it simply does not ask enough of a modern VRM to matter, so choose a board on its ports, memory support and price rather than on its power stages.

Zen 3 V-Cache parts share a memory controller and a power-delivery contract, so a board that handles one of them handles its siblings at the same power level. The number that changes between models is sustained draw, and that is the number the ranking above responds to. Released in 2022, the AMD Ryzen 7 5800X3D sits at 120 W.
