Wait, so I'm seeing posts/comments saying use SATA because Molex is dangerous, and some saying Molex is best because SATA is dangerous, and be sure to avoid SATA to 6-pin ... so what is the thing to use that won't burn your house down?

I've currently got risers with Molex connectors being powered by SATA using SATA to Molex adapters. I presume it's a miracle my rig hasn't just burst into flames yet? EDIT: Using these: https://www.amazon.com/gp/product/B01GU94QSQ/

Why have I never heard any of this before?
