New motherboard throwing sparks at I/O shield

Hello, today I've set up a new pc using Gigabyte B550 Aorus Elite AX V2 motherboard and I've noticed that when I turn on the PSU, motherboard throws sparks behind I/O shield at usb ports. However the PC runs fine.

I've never met with something like this. Should I be concerned and return it? Or what could be the problem? I'm sure I plugged everything correctly.

That is a fire hazard. Stop turning the machine on. Unplug it. Take it apart. And return or RMA the motherboard.

Ok, let's assume for a moment you did, but did you install all motherboard stand-offs?

With manual in hand  check, double check, triple check all your connections, it's easy to make a mistake. Dittos to what @Mark Kainesaid... is the board touching the case and causing a short? Or perhaps you dropped a loose screw or something under the board and it is causing a short.


Otherwise, RMA it.

For those who are curious, I also had other motherboard from Asus and when I tried that one, no sparks anywhere. So I can safely assume that it was faulty motherboard.

Don't worry, I checked everything, and yeah, of course motherboard was placed on the stand-offs (they were already preinstalled to the case). Sparks were coming from the boxed I/O shield panel.


However I'm kinda sad from this new build overall, because the Asus motherboard has misaligned I/O shield with the ports, and after some testing GPU has quite loud coil whine.. So much for silent PC. I think I'll be returning the parts back stick with what I have for now.


Edit: I read however that you should put you gpu under some heavy load for 24 hours to see if it goes away, so that's what I'm trying now.
