She's toasty now.

So, how you all doing? Good? I hope so.

 

My PSU cable just melted down and caught fire. 

 

Seasonic m12ii or something like that iirc.

 

My question. Likely hood of the rest of my PC being deader than a doorknob? Likely hood of my PSU being dead? Unless you guys respond with a "nah PSU will be fine, throw a new cable on her." I'm just gonna but a new PSU. But it was a catastrophic short in the cable, happened so quick I couldn't hit the kill on my surge protector fast enough. So do PSUs have protection in place to prevent total system killing in those cases? Is there a sliver of hope? Or am I building a new PC most likely?

-stares at mine that's laying on the floor- 

 

did the fire burn anything? was there a bad kink in the cable?

it's hard to say if anything is affected because we dont know which part is shorted

Nah, it's just the cable the caught fire. Smelled some slight ozone right before, if it would of clicked I'd of hit the kill early. I have everything cable managed onto the desk, so the desk is slightly singed but nothing else got burned up. Cable insulation is straight melted through.

 

Was scary af tho, ngl. Computer went dark, got really quiet for half a second, then the cable sparked and caught fire.

Which cable? the mobo or a component?

the cable

the external cable that's connecting the PC to the wall?

not internal cable?

[SupaKomputa]

specifically what cable?

[Cb2394]

External, from the wall to the PSU. Sorry, I thought I specified that

oh, then your computer is most likely fine

unless that's what caused the fire in the first place

Replace the cable. Switch the pc back on. 

Most likely the cable shielding failed or something of the like. 

 

Suggestion, watch the new cable, IF the PSU is over-pulling (over-drawing) then yeah the PSU could be at fault and may need to be replaced.

This will hit the PSU first, your part will probably ok.

The cable might not be good to handle the current, you should replace it with a better one.

Most PSU have a build in fuse, so if anything happens outside the fuse will take the damage.

Replacing the fuse would bring the psu back.

Ok, thank you guys. I think I have a spare PSU cable that paired to a 700w+, so I can try that. As for the fuse, any advice? Should I bother with that or just buy a new PSU?

I ask this cause I've never replaced a psu fuse before and if there's soldering my skills are very rusty

Try changing the power cable first.

Fuse is easy to replace, probably cost $10 for the technicians.

Don't replace it yourself, when in doubts get a new one.

Oh my Lord, thank you guys, saved me from dropping good money on a new PSU, new cable brought her back to life. Def keeping an eye and nose open for any potential issues

[BlueChinchillaEatingDorito]

Do you have any rabbits around? They love to chew cables

don't worry there's no soldering involved if the PSU is somewhat new

some are soldered btw.

make sure it's properly plugged, use a good terminals.

On full load, touch the cable, make sure that it's not warm or hot.

If still hot then probably there's something off with the psu.

This is one of those Holy Shit moments. Read your comment and this song came to mind. Might I suggest keeping a fire extinguisher near your computer from now on.

It's on the "immediate buy" list now. Essential PC hardware, RGB Class ABC Fire Extinguisher.

Kill-A-Watt may be in order to see if things are too out of line.  @SansVarnic

Good suggestion.
