I have an HP Z600 workstation. And I use A GTX 750ti for gaming on it. yes, I know it isn't an ideal gaming setup. But I don't have any other system to play on. I have connected the 6 pin power connector to a three pin connector which was coming from the CD Drive so does that mean I'm getting power from the drive or am I giving power to the CD drive should I connect the 6 pin connector to the connector that's coming from the PSU?
