I heard that SATA can only provide 54 watts max and molex can provide more wattage. Tons of these pcie risers on ebay have sata to pcie x6 for the actual pcie slot that the GPU plugs in to. If I have an rx 580 (I think it's a 180 watt card), and it is plugged into the x8 pcie connection on top, as well as the 16x on the bottom, will the GPU draw the power from the top first, then any residual from the bottom, making the SATA safe to use, or do I absolutely need molex, or does the GPU draw from the 75 watts on the riser first then anything else comes from the 8x connection on top?
The most GPU I would put in here would be the RTX 3080 when those prices come down, but for now I will likely get a few RTX 3070 cards, or some 2080 cards, maybe a radeon V11, or some rx 570's.
Am I overthinking this? Should I just use the SATA or buy molex to x6 adapters for the bottom PCIe riser?
Thank you!
