RTX 3080 PCIE cables are melting .

rtx 3080 pcie power cables are melting.

gpu – PALIT RTX 3080

psu – silverstone strider gold 650w 80+ gold power supply

i'm mining ravencoin and suddenly this happened . after the first time it happened , i replaced both pcie 8 pin cables (cables that came with the psu). And this happened for the 2nd time . the pcie cable connected to the left 8 pin connector seems to be more melted.i want to know if this is a graphic card issue ,power supply issue or a issue in the pcie cables .PLEASE HELP !!!!!!

edit – actually the cables weren't melted, the connectors of the cables have been melted.
