What's the problem? Cant seems to troubleshoot.. Front port and back usb port also same. Happens with 2 of my external HDD.. But pendrive doesn't shuts it down. USB hard disk powered dock doesn't shuts it down. Another hard disk adapter to usb also won't. What could be the problem? PC is fairly new including power supply.. Any ideas?
Forgot to add that if plugged in before turn on computer, the portable hdd works fine.

All pendrive or some pendrive only?
Sound like your pendrive have voltage issue which cause it to suck power causing your pc to shit down.

Kindda same like usb killer mechanise

Only 2 of my portable HDD! Pendrive no problem. Even USB HDD DOCKING with power plug also won't shut down my pc.

usually that happens when it detects a short. Can change cable for your USB HDD and try again?

Forgot to add that if plugged in before turn on computer, the portable hdd works fine.

likely there isnt much power supplied thats why when it try draw power it shut down

do this..

get a connector with DUAL USB head ; plug first the cable to the PC ; then only connect the HDD

I suspect sudden spike in usb power draw from the power supply's 5V line cause the PSU to shut down, indicating the weak PSU issue.

Psu only 5 months old. Cooler master gold 550w... can’t be right??

change cable

Sound like a bad cable problem

sounds like weak motherboard usb circuitry.
i have experienced that on laptop before. when portable usb hdd is plugged in, the laptop power is cut.

still unable to find out what is the issue. is my mobo bad?? my windows 10 is running fine though but my hackintosh has become super laggy and slow. could it be something is wrong with the mobo?

tho i not know whats the problem really is, but yeah ur mobo(a320 series) is in the trash category

B450 ok? its cheaper now.. can B450 overclock?

if u want cheapest but still ok = asrock b450m pro4
Ok = asrock b450 pro4 / k4
Good for OC = msi b450 tomahawk max

avoid asus for b450 series

asrock b450 pro4 also can OC right?

light oc is fine.
im using r5 2600, b450 k4 (which is actualy same as pro4 but different color scheme) . 3.8ghz @1.2v , dont want to push 4.0gz coz voltage required too muc for me.

Lazada selling RM295. worth?

If PC shutdown after plugged some USB drive, somewhere is short circuited especially the 5V + and -,
most likely the USB drive, usb cable, or the usb port short circuit.

This is one of the protection feature iirc.

TS mentioned "Front port and back usb port also same"
