This is my first time posting here so I apologize if this is in the wrong forum.
I recently purchased a EVGA Geforce GTX 660 ti as an upgrade for my Dell XPS 8300 and need advice on upgrading the power supply. My computer has a 460W power supply and the recommended power supply for the 660 ti is a minimum of 450W. I have been reading a number of threads on these forums that seem to have conflicting information. Some state that the power supply needs to upgraded while others state the Dell 460W power supply is fine because of conservative estimates.
I installed the card and it seems to be running fine - temperatures are 60-70 degrees when running games. However, I do worry that I may burn up something if I don't upgrade as it's so close to the recommended minimum.
Also, I was wondering about the 2 6-pin connectors needed to run the 660 ti. The Dell power supply has power cord that ends in a 6-pin connector. About 1 inch before the end of the cord, a second connector comes out of the cord. Is this sufficient to power the card or does it need two separate cords to properly power the card? It is obviously getting power but I have never done anything with power supplies or upgrading and while I have tried to read up on it, it's not that clear to me.
If I do need to upgrade, I have been looking at this:

Or would going with a modular power supply be better for my Dell case?
Thanks you.
