Purchased a Seasonic PRIME 1300W gold PSU recently for my system (Ryzen 9 5900, msi tomahawk x570 ,rtx 3080 suprim x), intending to take advantage of the hybrid mode for silence at idle/low load. However, when the PSU is placed in hybrid mode the fan spins up every 10minutes or so for about 5-7 minutes when the system is idling creating a rather disruptive experience, given the rest of the system is effectively silent,case is lian li 011 dynamic,what i have notice that in the box was only 1x8pin cable (8 wires) and 6x 6+2 pcie cables with 6 wires,my last gx 1000w from seasonic has pcie 3x8pin 8 wires,i used that 2 pcie 6+2 cables (6 wires+1x8pin cable 8 wires for the gpu,could that cause the fan spinning in idle because of some issue with the power on pcis slots

You didn't need a 1300W unit for your build unless you're looking at a multi GPU setup. As for the cables, they look about right;

When you're system is idling, bring up Windows 10's Task manager and keep an eye on resource usage. On that note, it's a good idea to have HWMonitor opened up as well. You will need to mention the rest of your specs as well in order for us to see the bigger picture.

Welcome to the world of Seasonic pseudo-high-end PSUs with a dumb fan controllers and not very quiet fan curves unless you go for Platinum\Titanium models, whereas everyone else in this price range already uses an MCU for fan control so you can program it whatever you want.
