molex to 6 pin ?

[bro]

building the pc parts my brother bought i found out i needed a molex to 6 pin adaptor,,the psu has one but the graphics card needed two,,anyway i bought this one as it was all that the guy had

looking on the internet most have two,,,would this be sufficient for this graphics card VTX3D 1GB Radeon HD 6870 with Dirt 3 Game- microdirect.co.uk


EDIT,found one with two molex connectors but out of interest would it have drawn enough power from one

yes i am sure one would have done but its down to the voltage rails
as some psu are made to look high wattage when really the 12v rail is weak
