Which 24-pin connector port should i use?

My motherboard has two connector ports beside each other. One is white and the other is black. Both can hold house a 24-pin connector, (but i believe the white connector just grounds the extra 4 pins)
Which connector should I use and what are the benefits of each one?
From googling around Ive learned the white connector is used with most older systems but the black port i can't find nothing on.

    The white one is the ATX header for your psu 20+4/24pin.
    The 4pin 12v atx connector from your psu goes at the top left near your cpu socket.
    They both need to be connected in order for your mobo to post.
    The black one beside the ATX is a floppy header.
    It will all be stamped on the board.
