true! my 850w PSU does not shut down, but the PCI-e cables become very hot (especially near the PSU connector). I am worried that such huge current will make the cable/connector melted.
I just come across an idea: many graphic cards have a 6pin-to-double-molex cable.

If we have two molex cable connecting to the PSU, and then connect to this cable, will it solve the problem?
anyone is using a 6pin-to-molex adaptor to distribute the current to prevent overheat? does it work?
