Why are some of the USB 3.0 connectors green and not the usual blue color

motherboardusbusb-3

I just got a new computer from a local shop in town. On the back it has two black USB 2.0 connectors. Two blue USB 3.0 connectors, and two green USB 3.0 connectors?

Does anyone know why two of them are green? What does that mean?

Best Answer

According to Wikipedia:

  • Black or White = USB 1.x or USB 2.0.
  • Blue = USB 3.0
  • Teal blue = USB 3.1.
  • Yellow, Orange or Red = high current/sleep-n-charge ports.

Teal looks pretty green to me ;) And since there's no official color spec for USB, yours could be a different (greener) shade even.

I'm going to say your new computer has USB 3.1 on it, and those are the "green" ports you are seeing.

You can probably confirm that by looking at your system/motherboard user's guide.
