Asus X870e Hero Front Type-C Charging Issue

[ROGn69afyhm6ijs]

Hello,
I am currently using the ASUS X870E Hero motherboard in combination with a Cooler Master HAF 700 Evo case. I am encountering a persistent issue with the front panel USB Type-C port.

While the port is able to charge my smartphone without any problems, attempting to charge a power bank triggers a “Power surge on the hub port” error in Windows. The issue consistently occurs only with power banks, not with other USB-C devices.

To troubleshoot the problem, I have already:

• Reinstalled the operating system from scratch,
• Reset the BIOS to default settings,
• Verified the front panel Type-C header connection to the motherboard,
• Reinstalled all chipset and USB drivers.

Despite these efforts, the issue remains unresolved.

Could you please provide guidance on whether this may be related to a hardware limitation, USB power delivery behavior, or a known compatibility issue? Any assistance or insight would be greatly appreciated.

Hi..

Have you plugged in the 8 pin pcie cable into the motherboard (Below the 24 Pin atx connector ) ??

Yes, the cable is connected. So, should I plug the cable into a different port on the power supply instead of the PCI Express port?

Hi, don't think changing the port on the power supply would make any difference, I think your power bank is pulling more power than the port can supply, the usb c port specs are :

Hello,

The technical specifications of the power bank show a maximum of 20V and 1.25A, which corresponds to 25W. That’s almost one-third of what the port provides.
