you may or may not see melted plastic. if you do see melted plastic, then yes you will need to replace the motherboard and psu.
the psu is not the culprit! you only need to replace the psu if the atx connector is melted.
the problem is the gpu is drawing too much power through the pci slot, which is causing the board to draw too much power through the 12V, which is tripping the surge protection in the PSU. this is very common with dual-gpu cards. the solution is to replace the motherboard with a high-end board that has molex connectors specifically to supply extra power to the pci slots, or pick up an EVGA Power Boost.
