Why you shouldn't use a well made 4 pin molex to (6+2)8pin pcie adaptors

Why you shouldn't use 4pin molex to (6+2)8 pin pcie connectors , specially if they are well made
This is a great example of a person that bought a quality adaptor that took the beating , but sadly the single 12v pin in the back of that psu couldn't , because its not made for a sustained load greater than 8A , Ironically he might have been better off buying a crappy adapter that would melt before the pin in the psu
