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?

Your hard disks probably would not even spin up and I would be surprised if the system even POST'ed with less than 10v on the 12v line. | Report abuse Reply to smeezekitty jnkweaver Motherboard Expert January 18, 2013 8:16:37 PM I would agree that it is not likely 6.8V on the 12V line. Seems like a bad sensor. Of course that doesn't mean that the 12V line isn't bad. | Report abuse Reply to jnkweaver Ask the community Post an answer Tom's Hardware>Forum>Motherboards>Serious +12v drop> Related ressources: Forumserious voltage drop from my PSU ?
