The following list is based on facts, ranked on power delivery and known problems. The list will include boards that support CPU overclocking available at retail from different brands.
There are still differences in performance among boards of the same tier. As a result, those that barely made it into that tier will be in orange while those that are better than others in the same tier are in blue. Unless specified, boards sharing the same name and chipset in different form factors are ranked the same.

All current draw figures are based on Prime95 small FFT with AVX unless otherwise specified, in other words the worst case scenario.
Only often recommended sku of CPUs in the same generation and core/thread count configuration is named, others share the same rating.
Zen scales down frequency and voltage according to EDC (current limit) and TDC (thermal limit) settings of the motherboard so in theory you won’t cook the VRM of any board at stock, you just lose frequency.
For tier A and above, due to lack of feasible CPUs that allow testing of the boards at higher current ratings, there are some level on guessing in terms of how much more power the VRM can take.
AM4 (Athlon, Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9)
B550 and X570S Speculation: If you cant find the board above, then it should be here. If it's already up there, then ignore what it's placed here
TR4 (Ryzen Threadripper 1xxx and 2xxx) X399
sTRX4 (Ryzen Threadripper 3xxx) TRX40 (largely guessing since there's little data)
