I see people selling USB riser using the 3 pin- SATA connection to deliver 75W that normally run though molex. I know normal manufacturer have molex-6/8pin PCI-e convertor so molex is safe to use but SATA is for HDD which normally use 3W-5W. Is that safe to run on the long term? will the SATA power delivery enough wattage, or wont overheat/ melt
