Hey guys, so recently i bought the EVGA 500B 500W 80+ BRONZE PC Power Supply for my PC. When looking at the 24 pin bit I noticed a pin missing. Since I am new to this, I was hoping someone could tell if this pin is supposed to be missing or I should get a refund/exchange. I have attached a picture of it.

Thanks!
 
That specific pin was used for the -5V rail. Since that rail was only used for old floppy diskette controllers and some ISA bus cards that are completely obsolete, complete reference to the -5V rail was removed from the ATX12V specifications back in June, 2004.
