So how do you connect the cables with no manual showing which end goes to motherboard and which to power supply? This is regarding the 8pin CPU cable. Both ends have different shapes. Both ends can be swapped either way. One end says CPU and the other Type 4. What on earth is TYPE 4??? Second part, there is nothing on the power supply showing where to connect on PSU. It only says PCIe & CPU for 4 ports. I can only guess it's the 4th because the CPU was written after PCIe.

I'm looking to buy the quieter PSU. the 750 watt seems like it should be quieter. But I'm not able to find any proof. With a 8700K and 1080ti, I'm guessing the power usage will be somewhere around 450-500 watts so either one should be fine. Is there a real side by side chart showing the exact dB for certain wattage?
