Prosto z Intela:

The PCI 2.1 bus works with two different types of cards: 3.3 volt and 5
volt. These two different types of cards cannot be accidentally plugged
into the wrong slot, as the "keys" for the cards are on opposite ends of
the slot (most currently shipping motherboards have 5 volt connectors).
Of course the 3.3 volt and 5 volt cards won't work in the same slot,
with the single exception of cards which can operate with either voltage
(this is covered in the PCI spec). An interesting trivia note is that
the connectors used for PCI cards are the same as those used for MCA.
