So i have encountered an issue with my system recently which i have been running for about 8 months, it started with my keyboard and mouse turning off randomly or keyboard not coming on when pressing the power on and having to restart, Thursday night the system shut down and then came the usb over current issue.

So i teared down the system so only keyboard and mouse and the same thing occurred. So i tried without any attached and still the same error. So i suspected a faulty board which is the asus b350 flashed to support ryzen 3. Ordered a new board asus b450, which runs on a ryzen 5 2600x and 16gb ram, and the exact same thing happened!! That's 2 boards busted.

The only thing i can think of is the psu which is an artic blue 850 watt, which ive been running for the last year. Would a faulty psu cause the same fault on 2 seperate boards? Im guessing that the psu has a fault which is causing the surge but having never seen this error. Would ram or cpu cause this issue? The case i have is a lian li pc 011.

So i have purchased another board msi b450 tomahawk and a egva 600 watt, i can see that the psu has over current protection.
 
I think you made the right choice replacing the power supply, I've never heard of that brand and it doesn't seem to come with any safety protections or any efficiency rating.

Thank you, it doesnt have ocp protection from what i see, even though the EGVA w1 600psu isnt the top tier psu it does offer ocp protection and a better known brand than artic blue and from ive read the 850 watt isnt used for high gaming systems as im running 5700xt, so not sure why they even state a 850 watt tbh
 
no idea what said:
Have you unplugged the case USB headers too?

Yeah i took the usb headers off too, strangly enough when i plug the keyboard in it states 2 keyboards!!, when you plug the from usb it states 5 keyboards and that was on both mobos. Something is definitely frying my board, even tried resetting cmos

Let us know how you get on.

Im hoping so , I've not gone for an asus this time apparently the asus mobo have the usb over current issue, there is no jumper on the asus board for the usb to regulate current, but cant see it being the ram or cpu as surely they would show up seperately from led indicators. First time ive seen this error so running out of options
 
Have you tried running the system outside of the case? Have a look inside of the USB ports to check for any damage too.

Tried both the old board and new one outside the case, checked all the usb ports even on the new mobo. Tried a seperate psu and same error. I think the old psu has failed causing the short to the board thats the only thing i can think of as the artic blue isn't even a graded one 80 + but illl find out tomorrow when i get the new mobo and psu third time lucky.
 
Update :

So after 2 motherboard changes it was indeed the PSU, my system is back up and running.

these are the steps i followed for anyone that encounters this issue.

1. Make sure all USB devices are removed from the motherboard, that includes any case USB hubs (normally labelled usb on the wire which is connected to the motherboard). Switch on the Computer and see if the error still comes up
2. If the error still occurs you will need to test bench the motherboard (outside the case on a non-conductive surface). There could be a short from the case to the motherboard so having outside the case removes that possibility.
3. Check all USB ports on the motherboard preferably with a torch for no bent pins or anything that may short the motherboard. if the USB ports look clean check the back of the motherboard as some have the backplate attached to the board so it's worth checking no metal parts are hitting the board.
4. Turn the system on again if the error still occurs and system shut down after 15 secs. Try removing the CMOS battery for 1 minute and try again.
5. If your at this point very likely your motherboard has a fault, I would also recommend not using the same PSU on a new board (as i experienced the hard way and the same fault occurred on a brand new board!).
6. When assembling the new board with a different power supply start up slowly i.e. one stick of ram and CPU with heatsink & GPU, See if it boots, if it does with no error, insert the next ram and test again. Then one by one start attaching usb devices only keyboard and mouse. At this point the motherboard should boot up and ask you to update the bios, at this point you should be good to go, but the same process should be applied when putting the motherboard into the case. Take your time don't rush and the system should work smoothly.

I would not recommend buying a cheap PSU and the price you pay for is the quality you get i.e. if you buy a PSU 850 watt that's £40 it's very likely rubbish and does not provide over current protection, therefore if the PSU fails it will take your motherboard with it. I learnt the hard way and £160 down because i brought a PSU thinking it was up to the job only finding out after that the 850 watt psu is not for gaming!
