Ryzen 5 7600 BOX
ID-Cooling SE-214-XT cooler
MSI Pro A620M-E (lastest BIOS from MSI)
Jazer 2*16GB 4800/6400MHz (XMP, EXPO)
M.2 Netac NV7000 2TB (4x4)
RTX 3080 10GB
PSU 1100W AeroCool (and Zalman Acrux 1250).
Wireless combo (keyboard+mouse Logitech) and Wi-Fi TP-link in USB.

This system works fine only one week. I was playng World of Tanks, when system hangs up. After reboot i saw "Over current have been detected on your USB device. System will shutdown after 15 seconds to proteсt mainboard".

Reset BIOS, removed battery, used jumper for safe boot, removed all USB devices, m2 and 3080, used another PSU - nothing helps. Checked all ports for shortage - all fine. No symphoms and no damages on board.

You used the right positioned standoffs in the case? The IO-shield was not twisted “inside” the usb or lan port? This can happen easily, and I don't want to jugde you.

Could you try the usb device, aka ur mice/keyboard and the wlan one by one?

No case used. All USB devices works fine with my old system 5700X/B550.

Well it was a one time thing I guess? Could be a tiny surge but my suspect would be the wifi dongle.

Wi-Fi is working fine with my old 5700X/B550. I wrote it above.

It doesnt really matter if it worked with your old setup, it is just a way to figure out the culprit and best way to do this is checking one by one.

So what I found for today:
Board can run with a COLD START (after full disconnect from PSU, with removed battery, shorted CMOS CLEAR jumper and waiting 10-15 minutes).  Today I entered in BIOS and than I leaved the board working. For 30 minutes in BIOS it works with no hangs. I have flashed BIOS 1.40. So the HOT START (after reboot) is still "Over current in USB".

Okay that's one more step, could you still test it one by one?
