I've read so many versions of the powering PCIE risers story.

I've read that a riser draws 75 watts

I've read that you can power two risers off a 54 watt Sata cable

I've read that you should never power a riser off Sata as they cause fires

I've seen people on YouTube power only the riser and not the GPU WTF

I assume the truth is that I can power two risers of a Sata/Molex cable, as long as I power the GPU with a good PCIE power source?

I plan to use an HX1200i to power four GPUs for now, as it's the PSU I have. We will likely go to 12 GPUs and three smaller PSUs eventually. Assuming the profitability makes sense.
