PSU Cable Fried

[marcusdunn]

So my computer PSU cable obviously overheated. Oddly enough though this happen while the computer was asleep. There was no smoke or sparks that I could see or smell. It must of happened when I wasn't home. I changed out the cables and the computer is still running. Just want to know if anyone had an idea as to how this happened before I keep it plugged up again.

Here are some photos.

I noticed the plug won't seat correctly in the outlet anymore.

The PSU prongs, one is burnt. But is still working with other cables.

Cable is obviously done.

You need to have the cord fully plugged in or you will risk damaging the power supply/motherboard, or other components. What brand and model of power supply do you have?

It was seated correctly before but now that something happened they won't seat all the way in the outlet. The power supply is a extreme gear 800w psu.

So if you have a new power cord then the power socket is shot inside. Are you using a new power cord?

Thats the earth lug right? That means you have current running to earth, this is a sign of a short circuit. Replace the PSU.

Yeah the computer runs with the new power cord. So should I still need to replace thr psu?

 

[Okedokey]

If its working then good, but usually these things don't happen without something else being wrong.

Dont plug it back in. This can potentially start a fire, so replace the PSU. This is what happens when there is too much current for the wire to handle and it overheats, a short somewhere as okey said or bad connection. Make sure you get a good quality psu from a known brand.

Well I did have a space heater pluuged up, but they have been running together all winter. I was thinking maybe my girlfriend knocked the cable out like in the picture and that caused the short. But I'll get a new power supply anyway.

Thank you for your input .

Running a space heater is bad on the same circuit/outlet as your pc. Those heaters pull a lot of juice and can burn wiring easily.
