Serious +12v drop Tags: Gigabyte Connection USB Motherboards Last response: January 18, 2013 8:16 PM in Motherboards Share p0gits02 January 18, 2013 7:10:01 PM Is this a motherboard problem or psu problem? My system is at 90% load. BTW, my usb ports doesn't work properly if I connect 2 or more usb devices. Is this the cause of my malfunctioning usb ports?
