power surge on usb port unknown usb device needs more power, i tried every solution, tried to reinstall the drivers, 5 mins ago replaced the keyboard and mouse and i'm still getting it, not sure why, maybe i need to update bios or something, i tried literally everything, it shows from time to time, it's really annoying, if anyone knows the solution, please let me know
It might be a little difficult coming up with a solution unless we know a little bit more about the circumstances, so I have a few questions but also some things to check.
1) You mention that the message happens from time to time, but does it seem to be related to any particular activity? For example, does it happen you plug in a particular USB device or power on some USB device?
2) Devices like keyboards or a mouse draw very little power, whereas something like an external HD that has no AC adapter and draws all of its power from the USB port use a lot more power. Do you have anything like this plugged into a USB port?
3) If you do have any devices that draw more power from the USB bus, are they plugged into a USB 2 port or into USB 3+? If you have have any such device(s) plugged into USB 2 ports and you have an available USB 3+ port, try moving the device(s) to those ports.
4) If you are using a USB hub that is bus powered (in other words, it does not have a seperate AC adapter), then try plugging in your devices to a self-powered USB hub (a hub that DOES use an AC adapter). Remember, with a bus powered USB hub the power for ALL devices connected to that hub plus the hub itself comes from the single USB port that you are plugged into. If you don't have self-powered hub, try moving one or two devices off of the hub, if possible, and connecting directly to a USB port on the PC if you can do so. This is most important for devices with higher power requirements.
5) If you have an add-on USB card in your system, check the card to see if it has a power connector that needs to be connected to the power supply. Some PCI add-on cards can potentially draw more power than the bus itself will provide and require a seperate connection to the power supply.
EDIT:
Adding one more item to check:
6) Jiggle and flex all your USB connections both near the USB port on the PC or hub and towards the end of the device itself. You are checking to see if there are any problems with the cable, such as a short. If you can trigger the warning when you manipulate a particular cable, you may have a problem with that cable.
I agree with hsehestedt but would also say a Surge is too much power, can burn out electrical/electronic circuits. Not enough power would be like a brownout. Power bumps, quick off then on, can also cause damage.
When I get that power surge notification, my mouse and keyboard are still working fine, I flashed my BIOS to latest version and installed latest AMD Chipset Drivers and it's not happening anymore, I also replaced keyboard and mouse, old mouse had damaged cable and that was probably the reason, it was also 5 years old, regarding the AC power thing, yes, I have HDD external rack and inside of it I have an actual HDD, but it was plugged out and I doubt it was him, since it already has AC power cable which goes into the HDD rack and such, anyway, if I get this notification again, I will notify you, but for now the problem seems to be fixed, I also ran sfc /scannow and it finished within 10 seconds and it didn't find any corrupted files
Good. Sounds like good news for now, but if it happens again, do let us know. We're all here to help!
PSU in sig causes a red flag. Looks like you have a potentially PC-damaging PSU.
It's not bad PSU overall, bought it brand new a year or two ago from a certified vendor for around 45$, currently it costs around 50$ in my country, it's reliable but I did plan on upgrading my PSU (I was thinking to do it two months ago, but....) - just waiting for the best deal because most of the good PSU's are currently sold out and they're generally deficient. I was planning to get Corsair RM650x, I was also thinking about Seasonic and other brands, but Corsair is just the one I would go with due to a lot of recommendations and the popularity of the brand and this sole model.
