I just upgraded my system to an i7 730 and the above mobo. I have a USB audio interface connected to my system. When I power down the system my interface stays on. Nothing else is on, mouse, fans etc. I have to turn off the switch on the PSU or unplug the interface. I checked some other post that have problems with the system restarting after it's shut down but I'm not having that problem. I tried moving from the front to back USB ports but same thing. Any thoughts?
More aboutasus shut down
I still haven;t resolve this. I don't see anything in the BIOS that refers to USB Power Settings. I'm obviously missing something.
So the speaker system (or whatever) is still on and drawing power while the PC is soft off?
Check to see if your speakers support "Low Standby Power"
