I don't know your cards specifically but overheating is a common problem when you use multiple video cards in a single machine. Usually, the one sitting on top is drawing the heat from the others and overheat. Here's a couple of tips:
1) Put the card with the best cooler on top.
2) Spread your cards to help with the air flow if you can. Don't use contiguous PCI-express slots if you have more than 2.
3) Make sure you have a good air flow in your case.
4) If you have double slot cards, make sure that if your card has a rear exhaust on the second slot (where there are no video connector), that the case metal piece that block the slot is removed.
5) If you can, use water cooling. It makes a HUGE difference.
6) I am not sure that the power supply is a problem but the melting cable is definitely not normal.
