6 there is 5V and there is -5V.
8 5V is needed for io stuff (like the drives), -5V was used for the ISA slots.
10 When the ATX standard was created, one of the 20pins/21cables was -5V.
12 Since -5V is not needed anymore, it was dropped some time ago. The connector
13 is still 20pins 'wide', but one of them is empty.
