[H] Power connector Sapphire Radeon X1950 PRO

[Winterlight]

I just picked up a Sapphire Radeon X1950 PRO 512MB AGP on Ebay

It has two power molex connectors on the tail. Unfortunately the 
manual doesn't mention these.

I am not concerned about the power as I am running a PCP&C 510. But 
do I need to plug both of the molex connectors  in individually to 
the power supply, or is one is one of the molex  some kind of a  pass through?

I assume this would use regular ATI drivers?
