Ausus PQS SE2 problem

Hi @ronarany

Disconnect any USB devices connected to the motherboard and check if it starts up OK without the message appearing.

The message is indicating that a USB device is drawing too much power from one of the USB ports.

If you have more than one USB device connected you may have to reconnect them one at a time and check if a). they cause the error message and b). if not if they work OK when connected

Hi @ronarany

Turn off the PC and disconnect the power from the PSU and then use a magnifying glass and a strong light to visually inspect all of the USB ports i.e. the ones on the back of the motherboard and also any of the front or back of the PC case (if the motherboard is in a case) that may be connected to the motherboard via a cable¹.

In the port check if any of the pins are bent or broken and are touching each other. The pins should all be straight and parallel with each other and not touching.

Below is an image showing what it might look like.

If you do find a faulty USB port, then if it is in the case connected via a cable to the motherboard, you can disconnect the cable from the motherboard to solve the problem, although this may put some other good USB ports out of service as well.

If it is a USB port mounted on the motherboard itself you will either have to remove the broken bent pins from the USB port, so that it will no longer be working or unsolder it from the motherboard. Either option will render then port unusable.

Alternatively, if you do unsolder it, try to find a compatible USB connector and solder it in its place.

¹Here's a link to the user manual that will help with locating where the USB port connects via a cable to the motherboard. Download the manual and then go to p.1-23 Sect. USB.connectors.(10-1.pin.USB78,.USB910,.USB1112 to see where the header pin location is onthe motherboard.
