I just replaced my power supply, Roswell rp600v2 s sl with a used one, same type. The one I got has a 6pin PCI express cable and a second 6pin cable with no label but no 6+2(8) pin connector as it should. Can I get an adapter for the unlabeled 6pin connector to 6+2(8) pin PCI express to plug into the video card? I also have a cable with 2 plugs with 4 large pins, I assume this is the Molex connectors, one plugs into a strobe light and has another plug also with the 4 large pin set up, could I use a 2*4 pin Molex to 6+2(8) pin PCI express converter instead. Which would be the best route if so? Thanks in advance. Oh the video card is a geoforce gtx280.
