here's what I found for you:
most likely variable here is the move to a new case: high probability of a physical grounding issue.
Check if a small metal tab from the motherboard’s backplate (I/O shield) is accidentally poking into a USB port. If that metal touches the data or power pins inside the port, it will cause an instant shutdown to protect the motherboard.
Also check your motherboard standoffs: Ensure you didn't leave an extra brass standoff in the new case that doesn't have a hole in your motherboard. An extra standoff touching the back of the board can cause "phantom" power draws and instability when the board is under load.
Your motherboard has a feature that shuts the system down if it detects a power surge on the USB rails.
front and rear USB ports connect to the motherboard's circuitry differently.
Since you just moved to a new case, the Front Panel is actually the more likely culprit. the front USB ports are part of the case, not the motherboard. This introduces several potential points of failure:
You had to plug a cable from the case into the pins labeled USB1112 or USB1314 on your motherboard. If those pins are bent or if the connector is offset by one pin, it triggers the Overcurrent Protection immediately.
Case cables are often tucked behind the motherboard tray. If that cable is pinched by a screw or the side panel, the insulation can tear, causing a short against the metal.
some cases have poorly soldered USB PCBs. A single stray solder blob bridging two pins on the front port will cause the "USB Device Overcurrent Status Detected" error.
The rear usb ports on the other hand are soldered directly to the motherboard.
Check if the plastic "tongue" inside the blue (USB 3.0) or black (USB 2.0) ports is snapped. If the pins inside are touching each other, the board won't boot.
How to Isolate the Problem
suggested action:
Unplug the Front Panel: Turn the PC off and completely unplug the USB headers (the wide 20-pin blue one or the 9-pin black ones) from the motherboard.
Test Boot: If the PC boots fine without the front panel connected, the issue is your new case or the cable.
Inspect the Rear: If it still happens with the front panel unplugged, the issue is almost certainly the I/O shield or a stray standoff behind the board.
Also look closely at the USB 3.0 header (the big blue one). The pins are extremely thin. If you plugged it in at an angle when building in the new case, you might have crushed a pin.
