Mind blank vs Words of power

[Chalys Probus]

Hello everybody,
coming from 24 years playing D&D, we had this doubt playing now Pathfinder for some months: does Mind blank protect against the Words of power (Power word blind, stun and kill)? In D&D 3.5 it does, but in Pathfinder the spell changed a lot and now it just gives a +8 bonus to the saving throw, that means against spells that allow a saving throw and not spells which don't allow that

Thanks in advance

Seems pretty straight forward to me ... by RAW Mind Blank will not protect you (i.e. prevent or allow a save) against the Power Word 'group' since they do not allow a saving throw.
