So my old nVidia 9800 Gt finally crapped out, and I purchased a GTX560 Ti to replace it (the EVGA 01G-P3-1561-AR GeForce GTX 560 Ti, to be exact). Whereas my old 9800 GT required only one 6-pin power connection, the 560 GTX requires two. Unfortunately, the adapter for the second 6-pin connector has two P10 male connectors, while the ribbon from my tower's power supply only has one P10 female receptor on it.
My question is whether there is some sort of adapter that would allow me to convert one of the other female receptors on the ribbon (P7, P11, etc.) into the second P10 receptor that the GTX560 requires? Or do I just need a new tower with a more up-to-date power supply?
