Review on Dual 6 Pin Female to 8 Pin Male GPU Power Adapter Cable - Braided Sleeved, 9 inches - TeamProfitcom by Keith Montague

Connected to two 6-pin source cables, tried to turn on the PC, won't turn on. After a little checking (tightening the cable, etc.) it turned out that this connector gets very hot. immediately turned off the computer and tried to disconnect the cable. It fused to one of the 6 pin connectors and required pliers to disconnect. Not sure if there was a short circuit or something, just one of the 6 pin connectors got hot.
