Hello I'm building a rig and everything works when I mine without risers just with my GPUs in pci 16 slots in motherboard. But I am trying to expand and use risers. I tried sata adapters to 6 pin that come with risers and usb gets too hot, I tried using 6 plus 2 pin splitter connected to one of the 8 pin cables that powers gpu and usb got even hotter and bubbled. I did some research and people say that I need to use 8 gen risers and not 6 gen risers that I use. So I just ordered 8 gen risers that have sata upfront without any adapters, will those work? My psu only has 2 gpu slots which I already use, ready are sata, and 2 cpu 8 pins and 2 unmarked 8 pin slots. Does anyone have 3070 rig that uses risers and my type of psu? How do you power those risers?? Thanks a lot)
You really shouldn't be using SATA based risers as you're setting yourself up for a potential fire. SATA's power handling and gauge of cable isn't up to the task to supply enough power to the riser for it to perform at spec.
You should be using 6 Pin preferably as it supplies more than the 75W of power that the riser needs to perform.
Only use the 6Pin's on your risers and use the VGA 6+2Pin's for your GPU's!
Yup I got these risers which don't have sata. I'll be using 6 pin to power them:
