If Intel's TDP figures aren't actual power consumption figures, how do I go about sizing a PSU?

How close do you want to get? Budgeting about 200W per socket for “normal”-ish CPUs and 400-450W per socket for latest EPYC should get you in the right range.

In that case, just copy someone else’s homework. Look up what Supermicro is using for wattage in 1U non-GPU servers, and use those numbers.
