SSnack Posted January 22, 2020 Share Posted January 22, 2020 I'm asking here since I can't seem to find it anywhere on the packaging or website but I have a new machine with a Corsair CX650 power supply that does not power its usbs down when I shutdown my pc for the night, leaving my room lit up with my audio interface's leds. Many similar threads on other forums have suggested enabling ErP in my motherboard's bios, which exists but I'm not sure if this power supply has ErP support and if there are any known issues with it. My motherboard is the Asus rog strix b450-f gaming if it helps. Thanks. Link to comment Share on other sites More sharing options...
Vegan Posted January 22, 2020 Share Posted January 22, 2020 Try the feature in the BIOS and see if it works or not. Link to comment Share on other sites More sharing options...

If the USB is being powered while the system is off or in sleep that is going to be motherboard related and if there is an option to disable this it will be in your BIOS. You should reach out to Asus for assistance with your inquiry as they are going to be the ones who can assist. Link to comment Share on other sites More sharing options...
