molex is like 100+ watts up to 134w before really stressed..
sata you would be lucky to get away with 75watts.. i believe its like 54w safe limit.
6pin connector is safe to 200w.
be sure you discard those adapters they include, or repurpose wisely.
You're way off.

Molex is max 60W, but depending on rail it's connected to.
SATA is max 54W, but depending on rail it's connected to.
6 Pin is max 75W
8 Pin is max 150w
well that's the internet for you.
do you really think your molex is only drawing 60w from RX series cards at the riser while mining?
have you heard any news about sata connectors burning up with RX series cards at the riser when used for power sources?
i used to run my GAW Black Widow script miners off two 6pin power connectors and so long as i didn't go crazy with overclocking it was safeish and stable drawing over 200W from each connector.
