I have a wifi usb wingle plugged into one of the usb ports on the motherboard. Where I am from there are sudden power outages. The whole shuts down immediatly but the usb wingle stays powered on before turning off. Is this harmful for any componets?

Mobo: Aorus elite b560m
Cpu:i5 11400f
Ram: Xpg 8x2(16gb)
PSU:fsp hydro g pro 750W
Gpu: RX 6600

Likely some capacitor just providing power and then as it "drains down" the LED fades.

As for power outages, sudden and continual power losses will take their toll on affected electronics.

Files will get corrupted sooner or later.

Be sure to make continual backups of all important data. At least 2x copies saved to locations off of the host computer and off of the power grid when not being used for backups. Verify that the backups are recoverable and readable.

Consider a UPS if at all possible. One that will a few minutes time for you to gracefully shut down the computer when power outages occur.

And perhaps with some surge protection (Joules) for additional protection. However, that protection does not last forever.

UPS and/or Surge Protector - invest in a well known and well rated product available in your area.

Does the Usb wingle LED stay on permanently or does the LED eventually fade out before power returns?

Power outages prevent Windows from properly shutting and may also cause file corruption leading to more problems.

What, within the contex of your build, does the lit LED mean?

The led stays on for a few seconds and then fades out.
Power outage lasts for about an hour and for file corruption. Thank god never had that issue.

Pc's that are plugged in are Not Off, unless physically turned off at the psu, or unplugged.

Depending on which Windows On Timers (in power plan) are active, the motherboard, USB, and sometimes mouse, keyboard and even Wi-Fi/ethernet can and are usually still powered. The pc is technically still On as long as the psu can pass power through. Only the OS is technically Off.

So your USB dongle will always have power, unless the psu is fully Off and not in Standby mode (Windows Off). Just as you can plug a cell phone into a USB when the pc is 'off' and still charge the battery. You can turn that option off in Windows power plan and/or bios by changing USB ports to Selective or Off (not recommended).

USB and hdmi and DP can require a 'handshake' to activate the port. This always happens when a USB item is first plugged in, windows goes through a recognition process and allows the USB to function. If you power 'off' the USB in bios, Windows may or may not recognise the USB as present when you push the power button, requiring you to unplug and replug the usb item. That gets tedious, especially with a Wi-Fi dongle. Best to just let it be, it's not harming anything since it's operating according to design.
