OK, I have read that it is best to use 2 seperate lines to power the Ultra. How do I determine which are unused? Is there something inside the power supply I should check? Or should I just use lines that have nothing connected to them already? I only have 1 HDD and 1 CDRW-DVDROM combo drive, I run these on one line with 2 molex plugs on it. I have at least 2 lines with nothing connected to them, should I just use one molex from each of these to power the Ultra?
