  • GTX 1080

The title says it all, when the case's front side usb c cable header is plugged into the motherboard I can't get any power to the PC. With it powered down, my PSU gives off power because I can see the LEDs light up on the mobo even before powering on.

It all started today when I wanted to finally get around to seeing why my front usb c port never worked, I wasn't sure if it was a Windows problem or if I just plugged something in to the incorrect port.

So I took it open and just looked around, didn't touch a thing, noticed that everything was where it should be. I thought maybe it wasn't sitting correctly in the port, so I took it out, inspected it, saw that it looked clean, and plugged it back in. Then the problem started.

 

Well I just found out if I don't have it plugged in my PC gets power no problem.

Its just the USB-C thats not working?

Are you sure you are plugging the connector into the correct pins?

Any chance you can post pics?

 

It does sound like that USB-C connecvtion is cause a no power/post, however its easy to plug things into the wrong place sometimes.

Correct, JUST the usb-c front side port.

Yes I am correct its the proper port as it's the only one on my motherboard for it.

Sure can, give me a few minutes to edit this post with pics.

The connector is probably damaged.

Ugh, I just would love to know which connector, the mobo's or the cable

Yeah. You would have to try a different mobo or case to narrow it down. Odds are its the case.

 

Just to be 100% sure are you plugging the cable in the right way. I know its keyed but sometimes they still can be forced in wrong

My first thought was maybe buy one of these to test without having to take a pc apart.

They both look ok physically.

Are you sure you are plugging it in the correct way?

It only goes in one way.

 

If so, can you pull the cable/panel out and plug it into another system for testing?

Since all works fine with it unplugged, i would be its the cable, or front panel connector itself.

Unplug it and leave it?

 

I think plugging it into another mobo for testing is your best bet to narrow it down. Assuming it wasnt being plugged in the wrong direction. 🙂

ashamed to say

No shame, most everyone has done it at some point.

Thats why we suggest the tsing step.

 

At least you were big enough to admit it. 🙂

And fixed is fixed, good job.

Just to add to this, because I had the same problem and found this thread while searching for a solution:

 

In my case the connector on the cable was labelled incorrectly, so it didn't work because I put it in as the little arrows on the motherboard and the connector suggested. Putting it in the "wrong" way solved the problem. It's a Phanteks case.

I signed up just to reply to this topic as I can confirm the same issue AND same resolution on an ASUS Tuf Gaming Pro WiFi II where the header had an arrow that I matched with my front panel cable. When plugged in it would keep the board from powering up. I found this thread and revered the connection at the header and sure enough, the board powers up and I have USB-c use on my front panel.

 

I also own a Phanteks case Enthoo 719

 

Crazy but true.

 

THANKS!!!
