D975XBX2KR + power connector confusion

[craftech]

I was wondering if one of you could help me out.

I am building a new system (been awhile).

I have an Intel D975XBX2KR motherboard
http://support.intel.com/support/motherboards/desktop/d975xbx2/

A MSI RX1950PRO-TD256E X1950 PCI Express Video Card

A Fortron Source Blue Storm 500W Power Supply http://www.newegg.com/Product/Product.asp?Item=N82E16817104934

The power supply came with a six pin connector for PCIe cards but the MB doesn't have a header for it.

The main power connector on the PS is a 20 pin connector + 4 pin connector. Both plugged right in side by side. The +12v power connector on the PS was connected to the MB via a 2 x 2 to 2 x 4 adapter supplied with the MB as explained in the manual. No problem there.

The confusion is over the 4 pin (1 x 4) molex power connector header on the MB near the LAN/USB port on the back of the MB and the 4 pin (1 x 4) molex connector on the video card. I can't figure out whether both get connected to a 4 pin molex power supply plug or only ONE of them.

Any ideas?

Thanks in advance.

the 6 pin connector is to plug into a card that has a 6 pin connection on it . it does not plug into the motherboard
and the 4 pin molex on the motherboard is to supply extra power when using a PCI express card that consumes up to 75W other wise you dont need it.
I don't have it plugged in for my card.
