SUB 3.0 Type A internal pin

[xuvv]

Hi all, I have an asus strix h270i board, and its internal 3.0 pin header broke off, VBUS to be precise (next to the no pin), will it work if i plug it in? or is it better to try and fix it?

Vbus gives 5v to the usb 3 port that's on that vertical row of pins.

If you look at the picture, you'll see each vertical row of pins belongs to one of the USB 3 ports, they're just offset by one pin for keying purposes (so you don't plug the connector the wrong way around)

 

So yeah, you can plug it in, just one usb port won't work. You can try to insert a pin or a wire in the plug and connect the other end of the wire to that other Vbus pin with lots of care to not touch the other pins in the row.  This way you'll get power in both usb 3 ports.

 

An alternate way to fix it is like this... see picture below :

Basically, use some fine strand wire, one or two strands of wire from let's say some power cable or some network cable, and insert them between the two holes. In the picture, the yellow is the fine strands of copper.

 

Where you have the broken pin, insert some broken pin or some bit of solid core wire into the hole, so that the thin strands of copper are fixed and making contact with the metal inside the hole.

On the other hole that has pin on the motherboard, when you insert the connect in the header, those fine strands of wire will make contact with the header pin and the tiny strands will be thin enough that they won't damage anything... so now power will be sent through those fine strands of copper into the other usb port's 5v power

The fine strands of copper will not be able to carry a lot of power, but the length of the wire is short enough that it should be fine ... worst case scenario the thin strands will act like a fuse and simply break if the usb device consumes too much power.

sorry for necroing, just wanted to say thanks. It works quite good for USB or Phones! At least the port usable again! cheers and bless you, mate.
