Hello everyone, I wanted to ask a technical question about how PSUs work, my question is why my gpu's (vega 56 strix) power LEDs (the ones above the 8pin pcie connectors that tell you if the GPU is powered properly or has no power) keeps shining even after the PC is completely shut down? They always shine when the PC is turned on (and this is normal because they tells me that the energy fed to the GPU is normal without any problems; but the question is how those LEDs keeps receiving energy when the PC is turned off? I'm not expert in those technical aspects but I know that when PC is turned off, the only rail that keeps working is the 5v SB and the gpu should have NO connection to the 5v SB; so how do those LEDs keeps shining? (enabling ERP mode on bios solve the "problem" but was still curious about how does it work and if I'm missing something about this. (maybe other rails keeps staying on too or things like that) Thank you everyone and have a great day
