V12N is pin 14 of the 20-pin ATX connector, and is supposed to be the  
blue wire, running at -12 VDC.  It was used by ISA cards and an  
optional part of PCI bus interface, but is not normally used by  
anything.

V50N is / was pin 20 of the ATX connector, running at -5 VDC, but has  
been removed since ~2003; the -5V rail was used ISA cards, but is now  
obsolete, and pin 20 is prohibited from being present in modern PSUs.
