I've got new PSU, it have only one molex connector but there are some spare sata power connector on it. So I have two options:
1) Use molex splitter then use 2 molex->8pin. On one side, max currency for molex is 11A so 12V*11A=132W while PCI-E specification claims max usage 150W on 8pin. On other side, gtx970 power consumption ~170w, some of that goes via slot (up to 75W) so it shouldn't fully utilize 150w, right?
2)I have my hands on pretty rare sata power to molex adapter. I may use it to have second molex for 8pin adapter. On one side, sata power gives 1.5A per pin so 1.5A*3pins*12v=54W; 132W+54W=186W which enough based on specification. On other side, electricity won't work that straight forward, moreover, 3 sata pins are in parallel (?) so I guess it's possible that much more than 54W will be going through sata power due to its (possibly) lower resistance and melted wires usually are no good, huh?
So which option should I choose?
Changing PSU is not an option, there are no powerful flexATX PSU on my country's market at all.
