Power surge on the USB port

BrandonR · 2025-03-06T06:45:10-0500

Hello,

I've been having this issue power surge on the usb port or usb not recognized along with not having my ethernet not working. recently had to re-build my PC .. got it up and running but only can use like Wifi and bluetooth at the moment for my headset and just my keyboard and mouse.

what is connected by usb?

Just keyboard and mouse on the front panel running as a test. I'm also checking to see if any lose connections on psu

Looking at the manual for your motherboard, I see that there is a mix of USB 2.0 and USB 3.2 headers on the board.
I note from the Corsair website that your keyboard requires a USB 3.1 or better port type.
Perhaps it would be good to take a look and make certain that the USB motherboard header that feeds to your case front USB port(s) is in fact USB 3.2.

Hope this helps

Already have it plugged into a USB 3.2 on my front panel USB. I forgot to update my specs on the website so I just did that if that helps with anyone wants to help diagnose this.

In general, rear/back usb ports have more power than front ones.

Tried to plug my keyboard into the back and it immediately prompted me with the power surge on the USB port. Any other ideas?

Do you have another USB keyboard to try?

This will help to (hopefully) narrow down the problem area to keyboard, USB port front/back, or something else...

Here is another idea that may be helpful-->

Was your system hit with a power surge?

Was there a bad storm or anything recently?

If your ethernet is not working (was this sudden?) and your usb ports are complaining about power.....

No storms or power surges have happened. I just tried what the video above recommended.. same error popped up. going to try a new keyboard in a second and see what happens...

No other keyboard? Kind of looks like the keyboard could have an issue and trying to draw more power than the specs say it should.

tried another keyboard.. wouldn't even power on with one of the usbs in the back. tried another port and it powered on.. so i tried to plug in another USB device i haven't plugged in yet and sure enough.. surge error popped up again. and still no ethernet connection.

Is it a new motherboard?

BrandonR · 2025-03-06T09:45:59-0500

Not a new board. I've had this board since mid last year.
