Wiring a graphics card to a generic PSU - sufficient power wires on plug?

[Tommygunn]

My brother in law has a got himself a free computer to which I am going to donate my old Sapphire X1950GT graphics card. The problem is, is that I can't easily wire it in to the computer as it has a crappy generic PSU with only one Molex and several Sata power plugs.
What I do have, without slicing and dicing and getting out the soldering iron, is the adaptor cable below. What I don't know is whether this has a sufficient amount of wires I.e. 0V and 12V to provide power to my G/Card.
Any ideas?

Tom.

System power consumption with a Sapphire X1950 GT is less than 250W. I think you will be fine with the splitter mentioned above. You probably don't need much extra power to run the card. I assume there is at least a 300W PSU or greater in the system.

The PSU is only a 250W. However, the computer will only be used by his son for cartoons/films and maybe the occasional children's internet game. Nothing, I presume, overly stressful.
