Not sure if you meant "doesn't matter" as in you don't need to know anymore :P
The wattage your board will take all depends on what cpu you use (and graphics card) and what you plan on doing with it (OC'in, etc.)
Per se - boards will not determine what psu size you will need in total, so you have to take everything you want to use or add into account.
Best deal look at a site like this Linky Hurr~
that can help you calculate wattage.
If you no longer needed this information - then oh well x)
